Gas electron multiplier: performance and possibilities

Authors

Description

The gas electron multiplier produced with the polyimide film 100 um thick. The maximum gas gain obtained with gas mixture Ar/CH4(91/9) was 5000. No decrease of gas gain with rates up to 2\cdot10^4 1/(mm^2 s) was observed. The possibility of operation of GEM with and without MSGC is discussed
