Abstract :
MicroStrip Gas Counters (MSGCS) with strip patterns on bare and coated borosilicate glass as well as MicroGap Counters (MGCs) have been irradiated with 5.4 keV X-rays to investigate their high rate capability and ageing behaviour.
plication of semiconductive coatings under the strips of MSGCs results in an improved short- and long-term gain stability in comparison to counters with uncoated borosilicate substrates, for count rates up to 105 Hz/mm2. However, the absolute gain of a coated detector is significantly smaller than that of a conventional one. The MGC has high-rate characteristics, as good as those for coated MSGCs. Results on the ageing of MSGCs on coated and uncoated glass, and of the MGC, are presented.
