Paper Abstract

We present the first results from the successful fabrication of an optical imaging tube consisting of a pair of MCPs read out by a CMOS application specific integrated circuit (ASIC) developed for x-ray imaging called the Medipix2. The Medipix2 is an array of 256×256 pixels, each of which amplifies and counts individual photon stimulated events amplified by the MCPs. A multi-alkali photocathode installed in proximity focus above the MCP is used for conversion of incoming photons into photoelectrons.. The Medipix2 integrates these detected photons, and the binary values of these counters is read fast (~ 1kHz frame rate) and without readout noise. Initial imaging tests of this tube, including QE, resolution, background, dynamic range and microsecond shutter operation are presented..
