Abstract
The spectral efficiencies of energy dispersive Si(Li) photon counters have been measured using the storage ring BESSY as a radiometric standard source of extremely low photon flux of the order of 1 photon/(s eV). The detectors were irradiated with white synchrotron radia-tion when the storage ring was operated with only about 5 electrons stored. For energy calibration and measurement of the energy resolution X-ray emission lines excited by a 55-Fe source were used. Towards lower photon energies the efficiency is drastically decreased by the building-up of an ice-layer on the permanently cooled detector. By this surface contamination also the energy resolution of the detector is affected. The performance of detector can be recovered by a warming-up procedure.
