"MicroPattern Gas Detectors with Pixel Read-Out"

[ Full Article | Comments, Questions & Answers | Help | IIB Home Page ]


MicroPattern Gas Detectors with pixel read-out are position-sensitive proportional counters obtained by coupling a gas amplifying stage, provided by a GEM detector, to a charge collection plane patterned with pixel electrodes. Advanced PCB techniques, offering typical feature size of the order of a few microns, are used to construct both stages of these detectors, which show high detection efficiency, excellent spatial resolution and fast charge collection. In this paper it is shown how the design of the read-out system can maximize the intrinsic performance of these devices for two practical implementations, in the field of X-Ray Astronomy and Plasma Imaging.
