Paper Abstract

We describe the development of an imaging photon counting detector using microchannel plates and a wedge-and-strip readout system. Several detectors of this type have already been fabricated ranging from open face detectors for the Extreme Ultraviolet (EUV) (<1000 Å) to sealed tubes sensitive to Far Ultraviolet (FUV) (1000-2000 Å) radiation. Recently, we have developed a similar sensor to operate in the visible (400-800 nm) spectral region using a S20 photocathode. This device is compact and its construction is ruggedized and suitable for airborne and spaceborne applications. We will describe the results of our evaluations of the visible sensor in terms of their position resolution, gain, pulse height, quantum efficiency, non-linearity and dark count characteristics. Imaging applications of this sensor with a Fabry Perot spectrometer will be presented.
