摘要

制作了用于剂量和剂量率监测的化学气相沉积(CVD)金刚石X射线和伽马射线探测器，并在1 mGy/h至1 kGy/h范围内进行了测试。它们在灵敏度和线性方面表现出优异的性能，并且可以在高达100/spl度/C的温度下工作。在脉冲模式下也进行了低剂量测量。此外，在/sup 60/Co伽马射线下的辐射硬度测量表明，综合剂量高达500 kGy的长期稳定性。研究结果表明，CVD金刚石在恶劣的温度和辐射环境中具有辐射检测的潜力。

Diamond gamma dose rate monitor

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/spl deg/C. Low dose measurements have also been performed in the pulse mode. Further, radiation hardness measurements under /sup 60/Co 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.
