Description
The exposure to high charge and energy (HZE) particles is one of major concerns for humans during their missions in space. Microdosimetry is a valuable tool for characterization of radiation quality. Measurements with Tissue-Equivalent Proportional Counters (TEPC) have been performed for several years in space for investigation of solar particle events and galactic cosmic-rays. The response functions of these devices are analysed using accelerators in ground-base facilities. Monte Carlo simulation is an alternative option for design of new detectors and investigation of radiation effects. In this study we apply the Geant4-based application MCHIT (Monte Carlo model for Heavy-Ion Therapy) [1] to simulate several sets of microdosimetric data obtained with walled [2-5] and wall-less [6] TEPCs. MCHIT/Geant4 is able to reproduce in general the response functions and microdosimetric parameters for nuclear beams from H to Fe with energies of 80-1000 MeV/nucleon. MCHIT/Geant4 can be applied for investigation of radiation effects and characterization of TEPCs in space research.
