Abstract

Chemical vapour deposition (CVD) diamond X- and gamma-rays detectors for dose and dose rate monitoring were fabricated and tested in the 1 mGy/h to 1 kGy/h range. They show excellent performances in terms of sensitivity and linearity and have been operated at temperatures up to 100°C. Low dose measurements have also been performed in the pulse mode. Further, radiation hardness measurements under ⁶⁰Co gamma rays have demonstrated long term stability for integrated doses up to 500 kGy. The presented results demonstrate the potential of CVD diamond towards radiation detection in harsh temperature and radiation environment
