Response of Thermoluminescence Dosimeter CaF2: Tm to Low-Level Proton Beams Using Rutherford Backscattering.

Abstract

Low-level proton beams from a van de Graaff accelerator operated at 1-3MeV with proton dose from 1.48 to 94.56mGy using the Rutherford backscattering method were used to study the response of thermoluminescence dosimeter CaF2: Tm. The glow curves, TL output and sensitivity obtained were analyzed with respect to proton energy, dose and dose rate. The experimental results indicate that TLD CaF2: Tm may also be used as a proton dosimeter in the low energy range.
