A big advantage of hybrid pixel detectors is the possibility to use different sensor materials or radiation detector mechanisms. For X-ray, electron and other charged particle imaging and diffraction sensor materials like Si, GaAs, CdTe are possible. The last two materials have a high density and absorb more efficiently higher energy particles. For mass spectrometry, ions, neutrons and XUV micro channel plates (MCP) can be applied. With the MCP and a high voltage, single events generate electron avalanches that can be detected with the bare ASIC.
ASI has designed and offers solution for in vacuum detection of electrons and ions (mass spectrometry). For these applications, the detector is temperature stabilized with water cooling. Other possible applications are neutron detection, XUV and optical photon detection.
