Abstract
X-ray diodes(XRDs) have been calibrated on BEPC synchrotron radiation device. A simple model was used to describe the photoelectric emission of XRD photocathodes. Surface smoothness, oxygen and carbon contaminants were enough to explain deviations of calibrated sensitivities from the model's predictions for metal photocathodes.
