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 20MeV 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 on-line configuration, detector-grade high-purity CVD diamond shows a sensitivity almost four order of magnitude higher than that of ionisation chambers.

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 20MeV 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 on-line configuration, detector-grade high-purity CVD diamond shows a sensitivity almost four order of magnitude higher than that of ionisation chambers.
