Summary:The present paper reviews the Position-Sensitive Thermal Neutron Detector (PDS). The latter being based in gas-discharge counters or on scintillators doesn't achieve to realize high efficiency, good positional and temporal resolution at the same time. PSD using micro-channel plates and foil converter possesses good positional (dX < 0.1mm) and temporal (dT < 10ns) resolution, but low efficiency (Ed < 2% for Li converter). The Micro-Channel Converter (MCC) for detection of thermal neutrons and their actions are discussed here. The computer model of conversion thermal neutrons with Li-converter is studied with Monte-Carlo method and the obtain results are given. It is now possible to compare the predicted results with experimental measurements. Also various converter substances may be simulated with our computer model, B and Gd in particular.
