  • Abstract
    We report on the efficient operation of a CsI-coated GEM photon detector. We describe its operation mode and the dependence of the single electron detection efficiency on the electric fields. Conditions for obtaining full efficiency of photoelectron extraction and their focusing into the GEM apertures, in 1 atm CH4, are presented. The quantum efficiency of the CsI-coated GEM is 35% at 150 nm.
