  • In the spectral range from 5keV to 6.5keV,absolute calibration of the quantum efficiency of the AXUV-100 silicon photodiodes(as the transfer standard detector)has been derived from the filled Xe total absorbing ionization chamber used as absolute detector at Beamline 4W1B of BSRF.The calibrated efficiency of the AXUV-100 silicon photodiodes is spread to soft X-ray range as the efficiency of the AXUV-100 has a fine linearity from 50eV-6keV.The flux spectrum from Beamline 3B1A and 4B9B has been absolutely measured by the AXUV-100.The sensitivities of some soft X-ray detectors for inertial confinement fusion have been measured with the second standard silicon photodiode (AXUV-100).The measured results of XRD(A1 cathode)are correspondent with ones of LLNL in error range.

Abstract: In the spectral range from 5keV to 6.5keV,absolute calibration of the quantum efficiency of the AXUV-100 silicon photodiodes(as the transfer standard detector)has been derived from the filled Xe total absorbing ionization chamber used as absolute detector at Beamline 4W1B of BSRF.The calibrated efficiency of the AXUV-100 silicon photodiodes is spread to soft X-ray range as the efficiency of the AXUV-100 has a fine linearity from 50eV-6keV.The flux spectrum from Beamline 3B1A and 4B9B has been absolutely measured by the AXUV-100.The sensitivities of some soft X-ray detectors for inertial confinement fusion have been measured with the second standard silicon photodiode (AXUV-100).The measured results of XRD(A1 cathode)are correspondent with ones of LLNL in error range.
