First Tests of Thick GEMs with Electrodes Made of a Resistive Kapton

Abstract

We have developed a new design of a GEM-like detector with single-layer electrodes made of a resistive kapton. This detector can operate at gains close to 10E5 even in pure Ar and Ne and if transited to discharges at higher gains they, due to the high resistivity of electrodes, do not damage either the detector or the front-end electronics. Gains ~ 106 can be achieved in a cascaded mode of the operation. The detector can operate without gain degradation at counting rates up to 10E4Hz/cm2 and thus it could be very useful in many applications which require safe high gain operation, for example in RICH, TPCs, calorimetric.
