Abstract
MicroStrip Gas Counters (MSGCS) with strip patterns on bare and coated borosilicate glass as well as MicroGap Counters (MGCs) have been irra diated with 5.4 keV X-rays to investigate their high rate capability a nd ageing behaviour. The application of semiconductive coatings under the strips of MSGCs results in an improved short-and long-term gain st ability in comparison to counters with uncoated borosilicate substrate s, for count rates up to 10(5) Hz/mm(2). However, the absolute gain of a coated detector is significantly smaller than that of a conventiona l one. The MGC has high-rate characteristics, as good as those for coa ted MSGCs. Results on the ageing of MSGCs on coated and uncoated glass , and of the MGC, are presented.
