    "abstract": "We further study the performance of single, double and triple Gas Electron\nMultiplier (GEM) detectors in pure noble gases at high pressures, in the range\nof 1-10 atm. We confirm that light noble gases, in particular He and its\nmixtures with Kr, have the highest gain, reaching 10^6, and an unusual gain\ndependence on pressure. Effects of the number of GEMs, GEM hole diameter and\npitch are investigated in detail. In He, avalanche-induced secondary\nscintillations are observed at high gains, using the metal photocathode. These\nresults are relevant in the field of avalanche mechanism in noble gases and\nX-ray, neutron and cryogenic particle detectors.",
