摘要: 利用神光Ⅱ激光装置,开展了化学气相沉积金刚石X射线探测器的相对标定技术研究。实验得到了金刚石X射线探测器与已绝对标定的平响应X射线二极管对X射线辐射的测量结果,计算得到金刚石X射线探测器平均灵敏度为1.19610-5 C/J,不同发次得到的灵敏度与平均值之间的偏差不大于13%。Abstract: The relative calibration of a chemical vapor deposited (CVD) diamond X-ray detector has been completed on the shenguang-Ⅱ laser facility. Signals of the CVD diamond detector and an absolute-calibrated flat response X-ray diode (XRD) for X-ray radiation were obtained. The average sensitivity of the CVD diamond X-ray detector is about 1.19610-5 C/J. The difference between average sensitivity and the sensitivities in different shots is no more than 13%.
