The response of a thermoluminescent dosimeter to low energy protons in the range 30–100 keV

This study demonstrates the thermoluminescence (TL) response of CaF2 : Tm (commercial name TLD-300) to 30–100 keV protons which were generated by means of a Cockcroft–Walton accelerator. The phenomenon in which the total thermoluminescent output from CaF2 : Tm (TLD-300) decreases with proton energy from 30 to 100 keV (with increase of LET) can be interpreted by the track structure theory (TST). The analysis of the glow peaks: P2 (131°C), P3 (153.5°C) and P6 (259°C), of TLD-300 show the oscillatory decreasing phenomenon as a function of incident proton energy, which can be interpreted with the TST and the oscillatory emission of electrons in a thermoluminescent dosimeter (TLD) that is caused by resonant or quasi-resonant charge transfer in ion–atom interactions in this TLD-300.
