Using of semiconductor detectors for spectrometry of heavy ions is known to have several methodological obstacles, which are necessary to be overcome. First of them is pulse-height defect (PHD), which is manifested in the form of apparently less energies than particles actually have. Second is plasma delay effect (PD), which prevents precise measurements (TOF technique) due to creation of...

This article describes the neutron detector based on a ZnS(Ag)/6LiF scintillator screen. The detector was designed for a purpose of astrophysical experiments. Light collection is performed via low-opacity polystyrene layer coupled with a PMT. The work includes numerical simulation data and experimental results obtained for MeV neutron fluxes.

The highly granular analogue hadron calorimeter was developed and constructed by the CALICE collaboration and intensively tested with both steel and tungsten absorbers. The active layers of the calorimeter are assembled from the scintillator tiles with the individual readout by silicon photomultipliers. The longitudinal and radial development of showers induced by hadrons in the energy range...

In the COMET experiment searching for the muon-electron conversion not conserving leptonic numbers, a scintillator-strip-based veto system will be used to prohibit the COMET detector from fake signals initiated by cosmic muons. In order to verify the efficiency of the system, we have built its computer model and carried out various simulations. To tune the model, experimentally measured data...
