Radiotherapy by beams of heavy charged particles has significant advantages in comparison with gamma therapy and electron beams. The main advantage of the use of proton and ion beams in radiotherapy is the possibility of the formation of spatial dose distributions, the region of maximum dose which most closely coincides with the shape of the irradiated target and falls sharply beyond its...
The performance of a single fast neutron detector was studied. Two different scintillators were evaluated, namely stilbene crystal and liquid EJ-301 (NEDA) scintillators. The efficiency and the calibration of each detector were done. Gamma rays and neutrons are well separated with both pulse shape discrimination (in single mode) and Time of Flight measurement of neutron-gamma particles...
Among theoretical approaches in unveiling the physics of ultra-high-energy cosmic rays (UHECR) one can distinguish the models assuming interactions of exotic super-heavy matter (including extra dimensions, Lorentz invariance violation, cosmic strings, dark matter particles or particles beyond the standard model etc.) and acceleration scenarios describing processes, in which the particles are...
In this presentation we report on the construction and performance of a gaseous detector with boron-coated blades in multi-grid configuration for fast neutron detection. The aim of this project is to adapt a solution originally designed for neutron scattering experiments[1] and use it for detection of fast neutrons by adding appropriate polyethylene (PE) shielding. Multi-grid configuration of...
The PPAC detectors are used for particle tracking systems in experiments with rare isotope beams in which particle identification is made in an event-by-event mode. The delay-line readout method allows measuring positions of beams. The serial placement of two detectors provides a possibility of determining a beam trajectory and a focus point. The critical factor for the proper operation of the...

Idea of the Multi-Wire gas-filled Electron Multiplier (MWEM) was proposed 20 years ago. Such type of detector was not widely implemented due to technological problems of it realization. At this moment new technology widely used for manufacture of MPGDs (GEM, THGEM, RETGEM, WELL, RPWELL, SRWELL, μ-RWELL, FTM). COMSOL simulation results are presented for 2 options of MWEM with single and double...
Gas Electron Multiplier (GEM) technology is widely used in many applications in nuclear and particle physics. It offers the potential to develop new gaseous detectors with unprecedented spatial resolution, high rate capability, sizable sensitive area, operational stability and radiation hardness.
The aim of research was to study the performance of GEM in two thickness: 50$\,\rm{\mu m}$...
The purpose of the current study was to investigate the effects of radiation on scintillators with SiPM senors and electronics elements. These components will be in the MPD detector which is one of the main parts of the NICA project and it's very important to know the sensivity level on radiation of these items. Therefor, three experiments were prepared in which the proton, neutron and heavy...
