Özet

We have studied breakdown mechanisms in MSGCs. For comparison, ''microstrip detectors'' without dielectric substrates were also tested. We found that detectors without substrates can always operate at gas gains 5-10 times higher than those with substrates, and that these higher gains are limited by self-quenched streamers. In the case of microstrip detectors with substrates, streamers also occur, but have a very narrow (in voltage) self-quench region and then transit rapidly to a ''gliding'' discharge. We have tested new geometries of MSGC which allow high gains (> 10(5)) to be reached.
