Paper Abstract

Results are presented for computational modeling an electron-optical system of the photomultiplier (PM) having time resolution of 0.5 ns at linear anode current of 0.1 A. Calculations are given for a cathode chamber, intermediate stages and anode unit of the photomultiplier. Calculations were performed with the help of a TAU application package. The developed cathode chamber assures a good focusing of photoelectrons on the first emitter. The configuration of the electron-optical system of the intermediate multiplying stage has a low spread of electron transit times and good focusing properties. The PM anode unit construction assures minimum waveform distortion of output pulses directed into the recording devices and a maximum linearity limit of the pulse light characteristic. Influence of a spatial charge in the anode unit on linear output current restriction has been discussed.
