Gaseous detectors

The invention of Micromegas and GEMs has made possible the development of a new generation of gaseous proportional detectors. By using a pixel chip as active (anode) readout, Time Projection Chambers become available where all information of the ionization can be read out. With the MEMS technology, developed for the integration of Micromegas and the pixel chip, a new electron multiplier may be feasible. The combination of this multiplier and an Electron Emission foil would result in a new and light detector with sub-nanosecond time resolution.
