摘要
Abstract
A method is described of measuring absolute spectral response for Au and CsI transmission photocathodes in soft X-ray streak camera,which is of great importance for the inertial confinement fusion（ICF） diagnostics.Transmission photocathode is conventionally employed as photo-to-electron conversion accessories.To derive quantity information of X-ray spectra,the absolute response of photocathode must be calibrated in a range of interest.Here Au and CsI transmission photocathodes with slits are calibrated respectively on Beijing Synchrotron Radiation Facility（BSRF）,in a photon energy range of 60 eV—5500 eV.This method has an uncertainty less than 10%and good feasibility.Calibration results are in good agreement with the calculation results obtained from the Henke’s photon emission model,with CH substrate effect revised.关键词
