MICRODOSIMETRIC MODELING OF THE RELATIVE LUMINESCENCE EFFICIENCY OF LiF:Mg,Cu,P (MCP) DETECTORS EXPOSED TO CHARGED PARTICLES

Radiat Prot Dosimetry. 2019 May 1;183(1-2):172-176. doi: 10.1093/rpd/ncy272.

Abstract

Using a recently developed microdosimetric model based on the Monte Carlo code PHITS, the relative luminescence efficiency of LiF:Mg,Cu,P (MCP) thermoluminescent detectors to charged particles from 1H to 132Xe with energies from 3 to 1000 MeV/u has been assessed. The results have been compared with literature data showing very good agreement for particles from 12C to 132Xe in case of model calculations performed in a site size of 40 nm. For 1H and 4He ions, the model overestimates the experimental values by ~10%. An explanation of this deviation as a consequence of fading effects has been included.
