Abstract :
The characteristics of prototype photomultipliers having high gain microchannel plates for electron multiplication have been investigated. Measurements are given of the dark current, quantum efficiency, anode pulse amplitude, electron transit time, single photoelectron time spread, and pulse height resolution of LEP HR 350 and HR 400 photomultipliers. The gain, the collection efficiency, and the single electron pulse amplitude as functions of the ambient axial and transverse magnetic fields have been measured and are discussed. Measurement techniques and descriptions of the measuring systems are given in detail.
