Abstract
We review recent work involving micro-strip gas counters with “advanced passivated” cathode strips. We present results from tests of a new variation of the MSGC, the planar micro-gap counter (PMGC), with very small (∼10 μm) anode–cathode gap. Gains of up to 3×104 were achieved and gain variations due to charging effects were less than 10% using an ordinary (uncoated) boro-silicate glass substrate. The PMGC showed no reduction in gain when subjected to an X-ray flux of 4×105 Hz/mm2 and survived exposure to alpha particles equivalent to 75 days’ running at LHC with no signs of strip damage.
