【摘要】 在北京同步辐射装置 3W1B光束线上 ,对天文观测用超软X射线( 0 .2keV— 3 .5keV)正比计数管探测器进行了系统地标定 .得到了正比计数管的死时间、计数率坪曲线、能量线性、能量分辨、窗材料透过比曲线 ;借助于已标定过的光电二极管探测器 ,测量了正比管探测器的能量响应效率 ,标定不确定度在1 0 %—1 8%之间 .另外 ,还对正比管系统在卫星上的六道记录和在实验室里的多道记录进行了对比 ,两种记录方式符合得很好更多还原

【Abstract】 A flowing gas proportional counter (FGPC) as the detector for astronomical observation in soft X-ray (0.2-3.5keV) range is calibrated on the 3W1B beamline at Beijing Synchrotron Radiation Facility (BSRF). The dead time, counting rate plateau curves, X-ray energy linearity, energy resolution and window transparency of the FGPC have been measured. By means of a calibrated photodiode (AXUV 100G IRD USA, calibrated in NIST) as a standard detector, the efficiency of the FGPC as function of photons energy has been obtained with an uncertainty between 10%-18%.更多还原
