摘要：

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%.
