我们研究了msgc的分解机制。为了比较，还测试了没有介质衬底的“微带探测器”。我们发现，没有衬底的探测器总是可以在比有衬底的探测器高5-10倍的气体增益下工作，并且这些更高的增益受到自淬流光的限制。在带有衬底的微带探测器的情况下，也会出现飘带，但具有非常窄的（电压）自猝灭区域，然后迅速过渡到“滑动”放电。我们已经测试了MSGC的新几何形状，可以达到高增益（bbb105）。
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 (>105) to be reached.
