Principle of operation of micro pattern detectors

Microstrip Gas Chambers (MSGC's), Small Gap and Groove detectors with an optional GEM foil are a recent development of gaseous micro- pattern detectors providing a cost efficient solution for a tracking detector. They provide good spatial resolution (~35 mu m) and can operate in high radiation environments (up to ~10/sup 4/ particles/mm /sup 2/). The laboratory course on micro pattern detectors tried to give an understanding of the layout and basic functioning of these detectors. (6 refs).
