| 摘 要： | 软X光闪烁体功率计(闪烁体光电管系统)是阳加速器及PTS装置上进行Z箍缩实验获取软X光总辐射功率及能量等参数的主要设备,光谱响应灵敏度是这套设备最关键的物理参数。为获取闪烁体功率计系统的光谱响应灵敏度,在北京同步辐射实验室进行了闪烁体与光电倍增管系统的光谱响应灵敏度标定,而要将闪烁体与光电倍增管系统的光谱响应灵敏度转换成Z箍缩实验需要的闪烁体与光电管系统的光谱响应灵敏度,还需要进行光电管与光电倍增管相对灵敏度标定,为此研制了一套光电管与光电倍增管光谱响应灵敏度相对标定系统。应用此系统进行标定实验,得到了光电管与光电倍增管的相对灵敏度,进而推出了功率计系统的光谱响应灵敏度。

| Abstract: | In Z-pinch diagnostics, the soft X-ray scintillator powermeter is an important instrument which is applied in measuring the yield of soft X-ray radiating from Z-pinch plasma on Yang machine and also on the PTS. The spectral responsivity is a key parameter of the powermeter. We calibrated the spectral responsivity of the scintillator and photomultiplier tube system from 50 eV to 1800 eV on Beijing Synchrotron Radiation Facility (BSRF) for obtaining the spectral responsivity of the powermeter. There required another sensitivity comparison between the photomultiplier tube and the photoelectric tube for completing the spectral responsivity calibration for the powermeter. We designed a relative sensitivity calibration system for this job. In this paper, we present the configuration and working procedure of the relative sensitivity calibration system. The calibration method and calibration results are reported as well. |
