Keywords: | Two-phase detectors; Gas electron muliplier | Issue Date: | 2007 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 580:1 (2007) 331-334 | Abstract: | Operation of Gas Electron Multiplier (GEM) in ultra-pure xenon was studied for gas at 25 °C, cold but not saturated gas at -90 °C and saturated xenon vapour at -102 °C. The most stable operation was observed at -90 °C for which the maximum visible gain of 150 was obtained from a single GEM. The maximum gain of [approximate]40 was achieved for saturated xenon vapour at -102 °C and of [approximate]25 for two-phase configuration at the same temperature. Continuous operation of a GEM in two-phase mode for periods of several hours was routinely achieved. | URI: | https://hdl.handle.net/10316/4360 | DOI: | 10.1016/j.nima.2007.05.168 | Rights: | openAccess |
