Spectral response calibration of Au and Csl transmission photocathodes of X-ray streak camera in a 60-5500 eV photon energy region

摘要: 本文利用北京同步辐射光源（BSRF）,提出了对条纹相机Au和Csl透射阴极谱响应灵敏度进行绝对标定的方案,给出了在60—5500 eV能区的绝对谱响应灵敏度,标定不确定度好于10%.同时,基于Henke等人的计算模型,给出了透射阴极的相对谱响应灵敏度,并且进行了CH支撑衬底X射线透过率的修正.结果表明标定值与理论值符合较好.

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.
