Charged Particle and VUV Detectors
(Open MCP Detectors)

The open micro channel plate system (OMCP System) is designed to be used with a vacuum system at pressure levels <10^-5 mBar. The Application field is photon, electron an ion detection. The conversion of the detected “particle” to secondary electrons is directly done by the MCP. To enhance the sensitivity for special wave length it is possible to use coated MCPs. For example a KBr or a CsI is a suitable Layer on the entrance Surface of the 1st.

If highly energetic particles are to be detected, an energy discriminating foil or layer may be applied between the beam and the MCP detector system in order to increase the MCP´s sensitivity to these highly energetic particles.
