    "abstract": "We study the performance of two-phase avalanche detectors based on Gas\nElectron Multipliers (GEMs) and operated in an electron-avalanching mode in Ar\nand Xe. Emission, gain, energy resolution and stability characteristics of the\ndetectors were studied. Rather high gains, reaching 5000, and stable operation\nfor several hours were observed in the two-phase Ar avalanche detector using a\ntriple-GEM multiplier. The signals induced by X-rays, beta-particles and\ngamma-rays were successfully recorded. Preliminary results were obtained in the\ntwo-phase Xe avalanche detector: the maximum gain of the triple-GEM in\ntwo-phase Xe and Xe+2%CH4 was about 200. The results obtained are relevant in\nthe field of two-phase detectors for dark matter searches, coherent neutrino\nscattering, PET and digital radiography.",
