Performance of imaging photon-counting intensifiers

摘要

Abstract: The configuration of imaging photon-counting intensifier (IPCI) is introduced, and the differences between traditional II generation intensifiers and the IPCI are given. Based on the single channel photon-counting technique, the measurement principle and method of the IPCI's key performances, such as dark count and photon gain are discussed theoretically. The experimental system has been developed. Measurement work of the two performances mentioned above are carried out under the condition of different MCPs operating voltage and temperature. The experimental result and its comparison with traditional II generation intensifiers are presented. !5
