Abstract
The operation of MicroStrip Gas Counters (MSGCs) on a Upilex (polyimide) substrate is described. The surface resistivity of the substrate was reduced by ion implantation or by coating with a thin film of nickel oxide. Results are presented concerning the surface resistivity and its stability. The lowering of the substrate resistivity allows MSGCs to operate at very high rates and several devices were tested in a high flux X-ray beam. Substrates with optimum resistivity showed no gain changes whereas gain changes were seen on those with higher resistivity
