Nanoscale calculation of the relative efficiency of 7LiF:Mg,Ti (MTS-7) and 7LiF:Mg,Cu,P (MCP-7) thermoluminescent detectors for measuring electrons and positrons

Abstract

Abstract Using the Microdosimetric d(z) Model in combination with PHITS-simulated specific energy probability density distributions, the relative efficiency of 7LiF:Mg,Ti (MTS) and 7LiF:Mg,Cu,P (MCP-7) thermoluminescent detectors was assessed as function of the incident energy for electrons and positrons spanning from 2 keV to 1 GeV. Additionally, the effect of the dopant concentration on the determined efficiency values was carefully investigated. Finally, the results are presented in combination with calculated specific energy frequency mean values and possible correlations were discussed.
