Abstract :
Gas electron multipliers (GEMs) have been overcoated with a high resistivity 1014–1015 Ω/ □ amorphous carbon layer. The coating avoids charging up of the holes and provides a constant gain immediately after switching on independent of the rate. The gain uniformity across the GEM is improved. Coating opens the possibility to produce thick GEMs of very high gain.
