Research

The field of my scientific activity is nuclear physics. My research concerns the strong interaction between nucleons in systems with many degrees of freedom, constituting nuclear matter. The primary experimental method is to study the course of nuclear reactions and the mechanism of heavy-ion reactions covering the Fermi energy region (30-100 MeV / A) and ending with ultra-relativistic energies. A separate topic of my activity is cooperation in developing the Jagiellonian - Positron Emission Tomograph (J-PET) based on plastic scintillators.

The evolution of the mechanism from deeply inelastic to multifragmentation reactions occurs near the Fermi energy, i.e., when the velocities of nucleons inside colliding nuclei are of the same order as the relative velocities of the centers of mass of these nuclei. The description of phenomena in this area requires considering the interaction with the averaged potential, i.e., the one-body interaction and individual nucleon-nucleon collisions, i.e., the two-body interaction, with appropriate weights. Work on the experimental systems to study the mechanism of nuclear reactions at Fermi energies included three innovative research devices: a gas detector using the dependence of range on the type and energy of charged particles, a gas chamber to identify the recorded fragments in real-time, and a multi-anode gas detector scanning the Bragg curve of energy losses.

In the range of ultra-relativistic energies, research aimed at detecting the signatures of the state of nuclear matter called gluon-quark plasma has become the area of my scientific activity. As part of the BRAHMS collaboration, I conducted this research at the Brookhaven National Laboratory on the RHIC ultra-relativistic counter-rotating beams accelerator. By joining the collaboration, I participated in designing and constructing three complex detection systems based on drift chambers in Krakow. These detectors have become the primary measurement tool in the BRAHMS experiment, particularly in measuring high rapidity events. To illustrate the technical complexity of the prepared measurement systems, let me add that the average production is  a few thousands of particles during a single collision with an ultra-relativistic collision of two heavy ions.

The future of nuclear physics in the next dozen or so years will be determined mainly by the ongoing intensive development of new generation installations delivering beams outside the stability path (SPIRAL2, FAIR, SPES). The new generation of radioactive beams aims to increase the intensity by several orders of magnitude and shift the upper energy limit from a few MeV/nucleon to 1 GeV/nucleon. Research using radioactive beams is not feasible with the best detection systems available today, such as INDRA (GANIL) or CHIMERA (LNS-Catania), due to the lack of mass identification needed to register isospin effects. The FAZIA (Forward A and Z Identification Array) collaboration, in which I participated for several years, defined the technical conditions and measurement methodology, allowing to build a detection system with high angular and energetic resolution and low energy threshold (1 MeV/n). It resulted in charge resolution up to Z = 70 and masses resolution up to A = 50. Achieving such exorbitant system parameters was possible thanks to the development of innovative solutions. They include entirely digital signal processing technique, fragment mass identification through real-time digitization of pulses and pulse shape analysis (DPSA - Digital Pulse Shape Analysis) with original mathematical algorithms, the use of silicon detectors with high homogeneity of doping through reactions with neutrons (nTD neutron Transmutation Doping).
