    "abstract": "We show that physics of multi-GEM structures is rather complex, regarding the\nnumber of phenomena affecting detector performance. The high-pressure operation\nin noble gases and the ion feedback are considered in more detail. It is\nproposed that the dominant avalanche mechanism in He and Ne, at high pressures,\nis the associative ionization. Ion feedback effects related to the dependence\non gas, pressure and gain and to possible avalanche extension outside the GEM\nholes are discussed.",
