Title: Characteristics of the J-PET detector simulated using GATE software

Abstract: Novel PET system based on plastic scintillators is developed by the J-PET collaboration. In order to determine performance characteristics of built scanner prototype, advanced computer simulations must be performed. These characteristics are spatial resolution, scatter fraction and sensitivity. Results of simulations of these characteristics will be presented during the lecture.

Thesis topic proposal

Study of the intrinsic 3D-structure of the proton at CERN

           The structure of strongly interacting particles, like nucleons and mesons, is provided by the theory of strong interactions – Quantum Chromo-Dynamics (QCD). In the framework of QCD the internal structure and properties of nucleons and mesons are determined by the interactions between their elementary constituents, quarks and gluons (commonly referred to as ‘partons’).

Title: Event Shape Engineering Technique in ultra-relativistic nuclear collisions

Abstract: The evolution of the system created in a high energy nuclear collision is very sensitive to the fluctuations in the initial geometry of the system. Utilizing these large fluctuations, one can select events corresponding to a specific initial shape. This method is called Event Shape Engineering. It provides an opportunity for the quantitative test of the theory of high energy nuclear collisions and understanding the properties of high density hot QCD matter. The technique will be illustrated on the grounds lead ion collisions in ALICE at LHC.

Title: Internal dosimetry in nuclear medicine treatment.

Abstract: Internal radiotherapy in oncology is therapeutic method of increasing importance. Despite many technical difficulties, possibilities which are given by this method, makes it extremely interesting. One of the most important tasks is prediction amount of radiation dose that patient will receive during treatment. That’s more important than determining the radiation dose that patient receives post factum. There is no reliable model to allow prediction of radiation dose as precisely as it is necessary for radiotherapy.

Title: Hydrodynamization of kinetic theory

Abstract: In ultrarelativistic heavy-ion collisions, hydrodynamics has been successfully applied to describe the evolution of the quark-gluon plasma. The applicability of hydrodynamics implies a significant reduction in the number of degrees of freedom. We study this reduction for a simple kinetic theory undergoing Bjorken flow.
