Abstract
We present the results of our further investigation of the Gas Electron Mut
iplier (GEM) photomultiplier consisting of a solid CsI photocathode coupled
to a cascade of GEMs. It operates with mixtures of pure noble gases or wit
h noble gases having small additives of nitrogen or methane. The GEM photom
ultiplier (GPM) reaches multiplication factors of 10(5)-10(6), allowing for
detection of single photons. We discuss the limitations of the GPM, impose
d by ion feedback and charging-up of the GEM elements, and some phenomena r
elated to the avalanche development in such devices. (C) 2000 Elsevier Scie
