Abstract
ZWe report on the efficient operation of a CsI-coated GEM photon detector. We describe its operation mode and the dependence of the single electron de tection efficiency on the electric fields. Conditions for obtaining full ef ficiency of photoelectron extraction and their focusing into the GEM apertu res, in 1 atmCH(4), are presented. The quantum efficiency of the CsI-coated GEM is 35% at 150 nm. (C) 2001 Elsevier Science B.V. All rights reserved.
