    "abstract": "Gas electron multipliers (GEMs) have been overcoated with a high resistivity\n10e14 - 10e15 Ohms / square amorphous carbon layer. The coating avoids charging\nup of the holes and provides a constant gain immediately after switching on\nindependent of the rate. The gain uniformity across the GEM is improved.\nCoating opens the possibility to produce thick GEMs of very high gain.",
