Paper Abstract

Photek manufactures a range of imaging photon counting tubes for resistive anode, centroiding CCD and wedge and strip readout systems. All three readout mechanisms have advantages and disadvantages. These are reviewed in this paper, by the way of examples of the various applications. All three systems can cover the electro magnetic spectrum from MeV photons to less than 1 eV and the means of doing so are briefly described. All three systems share similar limitations in count rate, counting efficiency and resolution. These limitations mainly stem from the micro channel plate structure and are the main area of development. Recent developments in the microchannel plate (MCP) tube technology have led to improvements in these aspects and are described in the paper.
