Scientific paper

We present a progress report on the development of intensified charge coupled devices (ICCDs) used in both analog mode with CCD integrating the output of an MCP and in photon counting mode where single MCP events are centroided to subpixel accuracy by the CCD and readout electronics. Spatial resolutions of 36 lp/mm have been achieved using a 15 micrometer pitch MCP in the analog mode. In the photon counting mode, individual MCP pores with the same spacing have been easily resolved indicating spatial resolutions of less than 10 micrometer. A discussion of the centroiding algorithms are presented, as well as a description of the electronic designs that will increase the diffuse event rate of the photon counting ICCD to 50,000 events/sec.
