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 (similar to 10 mu m) anode-cathode gap. Gains of up to 3 x 10(4) were achieved and gain variations due to charging effects were less than 10% using an ordinary (uncoated) bore-silicate glass substrate. The PMGC showed no reduction in gain when subjected to an X-ray flux of 4 x 10(5) Hz/mm(2) and survived exposure to alpha particles equivalent to 75 days' running at LHC with no signs of strip damage.
