Abstract
We present the results of our further investigation of the Gas Electron Mutiplier (GEM) photomultiplier consisting of a solid CsI photocathode coupled to a cascade of GEMs. It operates with mixtures of pure noble gases or with noble gases having small additives of nitrogen or methane. The GEM photomultiplier (GPM) reaches multiplication factors of 105–106, allowing for detection of single photons. We discuss the limitations of the GPM, imposed by ion feedback and charging-up of the GEM elements, and some phenomena related to the avalanche development in such devices.
