Abstract

The photon address digital detector system (PADDS) in its current implementation represents a cost effective and flexible solution for photon imaging. The system is built of an image intensifiers, a position sensitive photomultiplier tube with crossed wire anodes and a digital signal processor (DSP). TO avoid the complexities involved in the development of special devices. All components used are available from stock so as to achieve reliable specifications and low cost. The evaluation of the photon events by a DSP shifts the problem of detection from hardware to software and enables an exchange of the image intensifier to match the wavelength of interest. Design considerations and the status of PADDS are presented, results of an observation of the crab pulsar are shown and future developments are discussed.
