摘要

The possibilitiy 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 l0Gy. 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.
