Abstract :
To qualify for a good X-ray imaging detector of the next generation in space astronomy some basic features are needed. These include large active area, good spectral and spatial resolution, high count rate capability and robust structure. These requirements can be achieved with the gaseous electron multiplier (GEM). We have studied the applicability of the GEM detectors to X-ray astronomy in an operational environment of a satellite.
