Paper Abstract

The microchannel plate intensified CCD (MIC) photon counting detector system was developed to replace a common user photon counting detector, the image photon counting system (IPCS), at the Anglo Australian Telescope and at the William Herschel Telescope and the Isaac Newton Telescope at La Palma Observatory. The IPCS incorporated magnetically-focused four-stage cascade image intensifiers. This paper discusses technological aspects of the design and optimization of very high gain microchannel plate image intensifiers for such photon counting systems and particularly the optimization of device detective quantum efficiency.
