Abstract

The possibility of using CVD diamond films as dosimeters in radiotherapy applications has been tested in both off-line and on-line configurations. The thermoluminescent and thermally stimulated current responses after 20 MeV electron and 22 MeV proton irradiation have been studied as a function of the dose up to 10 Gy. CVD diamond compares favourably with standard off-line LiF dosimeters. In an on-line configuration, detector-grade high-purity CVD diamond shows a sensitivity almost four order of magnitude higher than that of ionisation chambers
