Production of helium nuclei in deuteron-deuteron fusion reactions
The main objective of this project is the experimental determination of the cross sections for the deuteron-deuteron fusion to the helium at the energy range close to the kinematical threshold for the production of the eta meson. Studies in this energy domain are interesting because of the large discovery potential of the new kind of nuclear matter in the form of the mesonic helium.The installation of the WASA detector at COSY opened a unique possibility to perform such a search with high statistics and high acceptance. Based on the successful test conducted in June 2008 by means of a deuteron pellet target and the COSY deuteron beam, the COSY Program Advisory Committee has recommended two weeks of COSY beam-time for the realization of this project. The research will be conducted in the framework of the WASA-at-COSY collaboration which is vice-coordinated by the consortium coordinator of the proposed project, and which constitutes part of the excellent collaboration between the Jagiellonian University and the Research Center Juelich. Five two-months research visits of the student in the group of Prof. Ritman are planned in order to prepare the experimental run, to take actively part in the measurements, to calibrate the detector components and to learn from the experts the data analysis and simulations procedures. The final analysis and the interpretation of the results will be carried out together with the world experts of the project field. For this aim the PhD student will visit for one-month the group of Prof. Quamrul Haider (who as a first have predicted the existence of the eta-mesic nuclei) and then the student will spend one month in the group of Prof. Satoru Hirenzaki.

Topic 9:

Study of the fusion process of heavy nuclei
The aim of this PhD project is to study the possibility of formation of hyperheavy toroidal nuclear systems in Au + Au collisions at 23 MeV/nucleon. The existence of nuclei with non-spherical shapes was first suggested by J.A.Wheeler, a pioneer in the development of the theory of nuclear fission. A proposal for a dedicated experiment was prepared in the Institute of Physics of the Jagiellonian University and has been approved by the PAC committee at INFN-LNS, in Catania. The experiment will be performed using the CHIMERA multi-detector system arranged in a cylindrical geometry around the beam axis at the superconducting cyclotron of INFN-LNS. Research tasks: PhD activities can be divided into following parts: Calibration of the collected experimental data (III-V reporting periods); Analysis of the data using different impact parameter estimators and shape sensitive observables (VI-VII reporting periods); Comparison of the experimental results with the predictions of dynamical models, such as BUU and QMD (VIII-IX reporting periods); Critical analysis of the accumulated results, writing the PhD thesis and project promotion (reporting periods X-XI); International exchange: Two 4-months research visits of the student in the group of Prof. A.Pagano at the INFN-LNS in Catania.

Topic 10:

Application of the Quantum Molecular  Dynamics to the description of the  fission, fusion  and spallation processes.
The aim of this PhD project is the investigation of the such heavy ion nuclear reactions (fusion, fission and spallation) that can have application in the energy production (fusion, fission) and the nuclear waste utilization (spallation). The main goal of the proposed thesis is to prepare the quantum molecular dynamics (QMD) code that will be used to describe results obtained from the future experiments conducted on the super separator spectrometer (S3, Ganil France). Preparation of the detectors and apparatus construction constitutes the experimental part of the thesis. The separator S3 will allow to study the isospin influence on the dynamics of the nuclear reactions. This separator is presently constructed in the frame of the Spiral2 project at Ganil. In order to describe the cross section of investigated reactions we propose to use the QMD-type model. Such models are presently ones of the most advanced tools used to investigate dynamics of the nuclear reactions. With help of this model one can study in fusion/fission phenomena such interesting quantities like the excitation functions, the coulomb barrier distributions and the cross section for the production of nuclear fragments in the spallation-like processes. Research tasks: Preparation and development of the QMD code (III-V reporting period); Tests of the QMD subroutines (VI-VII reporting period); Installation and tests of the scintillation ionization detector (SID) at the GANIL Lise3 line (III-V reporting period); S3 experimental program: test phase of the S3 detection setup (implementation/decay detector and emissive foil detector (VI-VII reporting period); Comparison of the experimental results with the predictions of the QMD model.

Topic 11:

Technologies for obtaining high radiopure materials and methods of low activity detection
In the framework of the project the PhD student will develop methods of low activity isotopes detection. To obtain a high detection sensitivity it is crucial, among others, to reach a very low internal background level of a detector. For this purpose, one has to use highly radiopure materials to construct the precise and sensitive radiation detectors and their shieldings. Additionally, it is important to utilize and improve signal processing and analysis procedures to further lower the background level. A wide cooperation with Professor Manfred Lindner from Max Planck Institut für Kernphysik in Heidelberg helps to improve argon, krypton and other isotopes detection techniques in the framework of collaboration with numerous experiments like Gerda, Borexino, DoubleChooz and Xenon to name a few. The PhD student will have a possibility to study behaviour of different radioactive isotopes under interest in gaseous and liquid environment. Very valuable for the student will be also a cooperation with Professor Schönert who developes novel techniques of radioactive gases detection in the framework of recently constructed experiments or those under development (Gerda, Borexino, DoubleChooz) which are placed in underground laboratories, e.g. LNGS in Italy, to ensure lowest possible level of background generated by cosmic radiation. Foreseen research tasks: Design of a Monte Carlo model of the LArGe detector, simulations of the possible background and detection efficiency (II - IV reporting period); Design of the online and offline analysis software for data acquisition system in LArGe. Adaptation for different germanium detectors (HPGe, BEGe, Segmented) (III - V reporting period); Measurements in radiopure environment, development of combined detection techniques (scintillations in cryogenic gases and interactions with germanium detectors), observation of rare events (VI - VII reporting period); Analysis and evaluation of obtained results; Adapting the techniques to other low background experiments (e.g. Gerda), preparing of the dissertation (VIII - IX reporting period). International visits: 8 x 2 months and 2 x 3 months visits in LNGS, Italy, to work with LArGe experiment. These stays are planned for III - VI reporting periods and VII, VIII respectively.

Topic 12:

Feasibility of such a detector has been demonstrated on a small prototype. The project will be carried out in a close collaboration with the Institute of Radiation Physics, Catholic University Leuven, Belgium, and Laboratoire de Physique Corpusculaire, Caen, France, which are among the leading laboratories in high precision experiments with nuclear beta decay. These laboratories are led by Prof. Nathal Severijns and Prof. Oscar Naviliat-Cuncic, direct partners in the consortium established for the described project. Research tasks: The Student will be responsible for the design and construction of a middle size MWDC prototype with about 40 sense wires and 10x10 cm2 active area. The MWDC will be assisted by a plastic scintillation detector used for energy measurement and as a trigger for the MWDC readout. The dimensions and surface finishing of the optical elements in the scintillation detector should be optimized using a light transport program (e.g. LITRANI package) (reporting periods IV-V); The Student should participate in the engineering work on the front end electronics, time and current digitizers and formatting of the data using FPGA technology (programming in VHDL). He/She should complete and test both on-line monitoring and data analysis software (reporting periods VI-VII); The Student should carry out extensive tests and optimization of the system and identify practical performance limits including the behaviour of the MWDC in a strong, non uniform magnetic field (~1 T) (reporting periods VIII-IX); With the complete middle size prototype the Student should perform the electron backscattering measurements from thick targets: Si, Ge, BC404 (plastic scintillator) (reporting period X). International exchange: Three 4-months research visits of the Student in the group of Prof. Severijns at the University of Leuven and at LPC Caen in the group of Prof. Naviliat-Cuncic.

Topic 13:

Applying  a novel C-GEM technology for ultra-light tracking detectors
The aim of this project is an application of a novel C-GEM technology for the three dimensional tracking of the ionizing particles. The Gas Electron Multiplier (GEM) detector covered by the recent patent of CERN is made by the thin (50 ?m ) kapton foil, copper-clad on each side, with high density of holes of bi-conical structure with diameter of about 60 ?m and so far was used only in a planar configurations. The GEM detectors technology was identified as the most suitable for the construction of the inner tracker aiming at the reconstruction of tracks from decay products of pairs of the quantum entangled kaons studied by the KLOE collaboration. In order to adapt the GEM detectors to the cylindrical geometry of the KLOE detector a C-GEM technology was developed in the Nuclear Physics Laboratory in Frascati (LNF). The C-GEM is a low-mass, fully cylindrical and dead-zone-free GEM based detector requiring no support frames inside the active area. Based on the well established collaboration between the Jagiellonian University, the LNF and the Rome-1 University, the PhD student will have an opportunity to take actively part in manufacturing and characterization of the full scale C-GEM detector which will be based on the large area GEM realized with the new single-mask photolitografic technique. This work will be conducted at LNF. The student will carry out tests and calibration of the detector in the laboratory conditions and will be engaged in its installation inside the KLOE system. Next task of the project will be the elaboration of methods for C-GEM on-line and off-line calibrations. In parallel the PhD student will carry out computer simulations in order to understand the operation of the detector in the environment with strong magnetic field and in order to estimate the resolution of the tracks reconstruction in a real experimental conditions.

Modular straw tube detector
The present project will include design, construction and tests of the tracker consisting of several straw modules equipped with the read-out electronics. The tests will be performed at the Cooler Synchrotron COSY-Juelich.For this purpose the tracker will be installed at the COSY-TOF experimental facility and will be used as a part of the detection system in measurements of the strangeness production in the proton-proton collision. The analysis of data from these tests will include study of the tracker performance as well as analysis of investigated physics channels of the strangeness production. The work will be conducted in collaboration with our highly experienced partners: Prof. Mauro Savrie from the University of Ferrara and Prof. James Ritman from the Research Center Juelich. They both have experience coming from construction of wire detectors for experiments at CERN and at COSY-Juelich. The Ferrara group will be especially engaged in the mechanical design of the tracker and in the tests with radioactive sources. In turns the Juelich group will be strongly involved in the detector tests at COSY and in the data analysis. In particular the Juelich group developed a new concept of pressure stabilized straw tubes which we plan to use in our tracker. The read out electronics of the straw detector should meet high requirements concerning the counting rates. We develop a read out system comprising three stages: (i) front end cards including preamplifiers and discriminators, (ii) digital boards with time-to-digit converters for drift time measurement and FPGAs for fast hit detection and (iii) concentrator boards receiving and merging inputs from several digital boards. The data from the concentrator boards will be transferred to compute nodes for event building and event selection.

Topic 15:

Cluster recognition in sampling electromagnetic calorimeter
The aim of this project is the elaboration of the reconstruction algorithms and its application for the determination of energy, time and position of entry of gamma quanta registered by means of the lead scintillating-fiber sampling calorimeter. The calorimeter based on the novel composite material solution has been build in the Nuclear Physics Laboratory in Frascati and it allows for the detection of the gamma quanta with the high energy resolution and, at the same time, it provides a high time- and position resolution over a large area of many square meters. A superior timing resolution of about 70 ps over a large distances of more than 4 meters makes this calorimeter unique in the world. Therefore, it is of importance to carry out the research of the possibilities of this kind of calorimeter also in view of the possible future applications in the medical diagnostic. The computer simulations will need to include the full process of the signal origin in the calorimeter including the energy deposits, light propagation in the scintillating fibers, charge collection of the photomultipliers and further digitalization of the electric signals. The procedure accomplished in the framework of this project will need to effectively identify split or merged clusters of energy deposits. The aim of this project will be also a study of the dependence of the shape of the energy deposits on the kind of the registered particles in order to establish possibilities of the particles identification. The validation of the functioning of the elaborated algorithms will be performed by the measurement of charged and neutral ejectiles from various reaction occurring in the positron-electron collisions realized at the DAPHNE collider. Research tasks: At the beginning of the project the PhD student is expected to learn the Monte Carlo simulation and reconstruction chain of the KLOE-2 experiment, the GEANT generator and the FLUKA simulation package. This stage should take about one year and has to be done in parallel with other tasks. The student should study cluster reconstruction algorithms and adopt them to the existing calorimeter. Detailed studies of the properties of reconstruction quality, reconstruction efficiency and algorithmic efficiency have to be performed. Special care is needed for investigation of systematic effects, e.g. cluster missing and fake reconstruction, inefficiencies coming from cluster overlaps, influence of the apparatus noise, signal cleanliness, etc. This is an analytic and time consuming task which should take about 18 months, till the end of the third year of the project. Final verification of the algorithm is going to be done during physics data analysis in one of the decay channels. As a good test ground for this one can use e.g. the ?decay. International exchange: This project assumes collaboration with the software group and code developers working mainly at the National Laboratory at Frascati in the group of Dr. Fabio Bossi. Therefore it is planned to spend there 4 months every year during the years 1, 2, 3 and 4 of the project. We plan 5 short-term visits of the student, 2 weeks each, during years 2, 3 and 4, to physics groups of Prof. Filippo Ceradini at the University Roma-Tre and Prof. Rafel Escribano, Autonomous University of Barcelona, to consult specialized topics on calorimetry and data analysis.

Topic 18:

Development of artificial neural network methods for complex multidimensional data analysis
The aim of the project is the development of Artificial Neural Networks (ANN) procedures for analysis of complex experimental data obtained with multi-detector systems installed at GSI Darmstadt and used in measurements of neutrons and charged particles at relativistic energies. The main and most challenging task of this project is to improve particle identification in the neutron detector LAND. The identification is particularly difficult when several neutrons simultaneously strike the detector in the presence of background signals induced by gamma photons and light charged particles. Such conditions were present in recent experiments performed to study nuclear multifragmentation (experiment S254) and spallation processes (SPALADIN). The resolving individual neutron and proton tracks is of crucial importance in the forthcoming experiment S394, which will be performed by the ASY-EOS collaboration in order to provide constraints on the symmetry energy at supra-saturation densities. Research tasks: Development of ANN procedures for the neutron identification and the impact parameter determination.

Topic 19:

Development of new hadron identification method based on Simulated Annealing
The aim of this PhD project is development of new hadron identification methods based on their energy losses in gas of large volume Time Projection Chamber detectors. The identification of these particles requires non-trivial fits which need advanced optimisation algorithms. One of possible approaches here is the Simulated Annealing Method, which is a Monte Carlo method for global optimisation problem. It could be combined with later, standard, Minuit package-based minimisation as well as with physics driven constraints, to get an unambiguous solution. Because of huge amounts of data, both the calibration and the analysis processes require automation. This could be achieved by means of parallel programming. One can also try to make use of pattern recognition methods. Hence, the student will have to study all mentioned computing issues and develop a dedicated software in the frame of the object oriented design. Reserch tasks: Development of new hadron identification methods (II-IV reporting periods); Application of these new methods to the analysis of experimental data collected for proton-proton collisions measured with NA61/SHINE detector (VI-VII reporting periods); Comparison of the experimental results with the predictions of dynamical models.

Fodor at the KFKI Research Institute for Particle and Nuclear Physics, Budapest. These stay is planned in the VI reporting period respectively.

Topic 20:

Development of the programmable electronics for the real-time complex analysis
The proposed project concerns upgrading of the triggering schemes of detector systems containing several thousands of elements to be read out. It involves use of modern Field Programmable Gate Arrays (FPGA) processors allowing for very fast and effective in real time rejection of not interesting events at an early stage of the data collection process. The focus of the project will be on the preparation of the new instant Track Finding System utilizing information from drift chambers at KLOE-2 and WASA detector systems. The system will utilize the existing information from 12-fold groups of wires and detect specified patterns, calculate number of tracks and perform other predefined parallel computations within less than 1 ?s. The information about hits in the detector will be transferred from 20 existing Amplifier-Discriminator boards (ADS) to Advanced Logic Boards (ALB). In order to diminish the number of necessary connections the information will be sent serially over optical links. All computations will be performed inside ALBs. The task of PhD will be to develop fast track finding algorithm to be implemented in the FPGA code. Research tasks: Development of track finding scheme(s) (IV reporting period); Performance of simulations testing the track finding scheme(s) (V reporting period); Implementation of the track finding scheme as FPGA algorithm (VI reporting period); Laboratory tests of the Advanced Logic Boards with implemented track finding algorithm (VII reporting period); Preparation of the trigger electronics in the WASA-at-COSY experiment with the Advanced Logic Boards (VIII reporting period); Data collection on rare decays of the eta and eta? mesons; data analysis and comparison with theoretical predictions; International exchange: The group from the Uppsala University is our current partner in framework of the WASA-at-COSY experiment.

Topic 21:

Development and applications of tracking of pellets streams
The concept of the cryogenic hydrogen pellets have made it possible to have bare high density hydrogen targets without any enclosing and disturbing material in internal-target storage-ring experiments. The pellets can be brought to the interaction region through meter-long thin pipes. This project aims at the development of the pellet tracking system (PTR) that could be used in the future PANDA experiment at FAIR and in WASA at COSY. This requires efficient detection and identification of individual pellets in a pellet stream of high intensity, typically 10k-20k pellets/s. The pellets have a diameter around 30 mum and a speed around 70 m/s and it takes about 60 ?s to pass through an accelerator beam with 4 mm diameter. The final goal is to be able to reconstruct the position (3D xyz) for pellets that are in the accelerator beam region at the time of a hadron reaction event with an accuracy of a few tenths of a mm. Pellet detectors can be placed at the pellet generator and at the dump at a distance of 1.5 2 m from the interaction region. A pellet trajectory can be extrapolated to the interaction region using the knowledge of pellet speed and direction. It needs a detection accuracy of better than 100 mum in transverse position (xz) and better than 2 ?s in time to reach the desired position accuracy at the interaction region. At The Svedberg Laboratory a unique experimental pellet station is located. It allows for production and monitoring of the pellets e.g. their regularity, granularity, stability etc. can be traced in real time be means of computer-steered set of photographic cameras. The experimental studies of pellet beam properties by the PhD student are therefore only possible in Uppsala. The application and test of the tracking system in a real experimental conditions will performed in the Research Center Juelich, where the developed PTR will be installed at the WASA-at-COSY target station. International exchange: Total of 12-months research visits of the PhD student in the groups of Doc. Andrzej Kupść at Uppsala University and of Prof. Hans Stroeher in Research Center Juelich; One month visit of the PhD student in the theory group of Prof. Johan Bijnens at Lund University is planned at the last stage of the project when collaboration with the theory group will be crucial for the interpretation of the results obtained in experiments done in Research Center Julich. Prof. Johan Bijnens is word leading expert in theory of low energy strong interactions in terms of chiral symmetry.

Topic 22:

Detector read-out system equipped with very large integration scale ASIC chip
The aim of this project is to developed and test the set of silicon tracking system (STS) which will consist of silicon microstrip sensors equipped with an advance self triggering large integration scale ASIC chip. The chip is actually under development in cooperation between Cracow, Heidelberg, India and Russian groups, and aims at fulfilling following requirements: (i) high integration scale allowing for parallel readout of about 120 channels, (ii) signal to noise ratio on the level of 20, (iii) self triggering architecture, and (iv) high level radiation hardness. The requirements of the read-out system under development are defined by the planned physical measurements in the field of high energy nuclear physics and there are no devices on the commercial market that could fulfil such requirements. Thus the R&D activities have been undertaken to developed ASIC blocs including dedicated support/readout boards. The proposed project is a part of this activity that will concentrate on the development of proper software procedures including read-out speed optimization algorithms that will specifically deal with architecture and the dynamic features of the chips. Research tasks: Study on the modern methods and programs used in simulation of the performance of the electronics devices (IV-V reporting periods); Simulation of read-out, data transfer and data processing from the STS detector (V-VII reporting periods); Implementation of the read-out algorithms using programmable devices like FPGA (VI-VIII reporting periods); Preparation of the prototype test line for STS detection modules for the CBM experiment (VIII-X reporting periods); Regular activities as a member of the CBM collaboration like: participation in STS working group meetings, participation in CBM collaboration meetings, providing internal documentation of the performed studies and obtained results using CBM Wiki Documentation Scheme (reporting periods VI-X). International exchange: Three 6-months research visits of the student in the group of Prof. P. Senger at the GSI/FAIR in Darmstadt; These stays are planned in the IV, VII and IX reporting periods respectively; Two 2-months visits of the student in IPHC Institute in Strasbourg (V and VI reporting periods) in order to get an expertise by the student from IPHC Institute ALICE people who build a silicon strip detection system for the ALICE experiment at LHC in CERN.

Topic 23:

Real time recognition of rear signals in large data streams using novel data processing technologies
The objective of the PhD thesis, proposed within this project, is to perform investigation of various possibilities of the off-line algorithm realization in real time in order to cope with a high multiplicity environment at very heavy (Au+Au) collision with expected data rates in the order of 250 MBytes/s with an average event rate of 20kHz. Data will be generated by several hundred of multipurpose boards (Trigger and Read-out Boards) equipped with local FPGA resources and optical Ethernet links for data transmission The successful implementation of such a trigger will allow to reduce substantially the data volume produced during the experiment. Certainly, the major part of the project will be the adaptation of the tracking algorithm into the trigger algorithm with special emphasis on its parallelization. There are currently several hardware possibilities considered for the trigger implementation ranging from FPGA implementation in dedicated Compute Nodes to commercial PC farm (with or without Graphics Processing Units) which has to be considered, too. The proposed solution should be verified with real data obtained by the HADES detector experimental runs. The work will be conducted in close collaboration and support of the GSI and Frankfurt University tracking and trigger groups. Research tasks: Simulation of HI reaction events. Studies of trigger algorithms using HADES analysis software (III reporting period); Studies of tracking algorithms and its parallelization possibilities (IV reporting period) ; Evaluation of best trigger strategy and concept of implementation in hardware (V reporting period); Implementation of the selected strategy of triggering; Performance tests with the data obtained by the HADES detector. Identification of problems in trigger and software optimization (VI-VII reporting period); Analysis of trigger performance based on collected data, conference presentations (VII? IX reporting periods); Critical analysis of accumulated results. International exchange: 5 x 3-months research visits of the student in the group of Prof. Stroth and Dr. M. Traxler at GSI Darmstadt. Consultations with tracking and trigger group at GSI. These stays are planned in the III- VIII reporting periods, and includes also participating in the HADES data taking periods. GSI is the host institute of the HADES experiment.

Topic 24:

Development of innovative detection techniques implementing fast pulse shape sampling and digital processing
The proposed project will be realized in frames of the FAZIA Collaboration grouping together more than 10 Nuclear Physics institutions. The most ambitious R&D (Research and Development) issues of the project concern the Front End Electronics (FEE) and the choice of the best Silicon material for the first two detection layers. Both issues are closely related to Pulse Shape Analysis, which has to be performed following a fully digital approach, treating the charge and current signals produced by our preamplifiers. New fast algorithms for on-line Pulse Shape Analysis and alternatively timing for ToF (Time of Flight) ought to be developed and studied. On the basis of the results recently obtained, a realistic goal to aim at is: charge resolution up to 70 and mass resolution up to 50, with low (1MeV/n) energetic identification thresholds well beyond the capability of the existing instrumentation. In order to design and implement a 4Pi array (over 10 000 of detecting cells) with such ambitious features, a great effort is to be dedicated to two main issues: the first one is to design a very compact FEE placed in vacuum next to the detectors and to optimize the fast link toward the on-line processing devices. To that purpose, amongst other solutions, ASIC (Application Specific Integrated Circuit) implementation of the FEE is applied. The second extremely important issue refers to the choice of the Silicon material. We have verified that known problems like channelling and non-uniformity of doping - which may limit (but not destroy) the performances in some standard applications (typically in ?E-E identification techniques) may render any Z and A discrimination technique based on Pulse Shape Analysis impracticable. The close cooperation with the industry may provide the necessary quality, also because our expertise in the field is expected to permit the necessary and prompt support for the in-field application-oriented tests of the material. Research tasks: Literature search on the general problem of the recognition of shapes: given as digital representation: the possible areas of conformity may be searched along following fields: (i) digital picture recognition, (ii) digital voice recognition, (iii) neural networks. Development of the Software for the detected particles identification, evolution of the mathematical approaches suitable to the problem (V -VI reporting periods); Running programs, analysis of the data from the data base accumulated until now during experiments, discussion, preparing publications, project promotion ? conference presentations (VII? VIII reporting periods); International exchange: Two 4-months research visits of the student in the group of Prof. Bougault at LPC/ENSI Caen, one 4-months visit in the group of Prof. Poggi at Florenze University. These stays are planned in the III, VI and VIII reporting periods respectively.
