Abstract

The main parameters of microchannel amplifiers – angular and energy distributions of photo- and secondary-electron emission – are determined by the emission properties of materials. These parameters depend on the type of materials, the thickness of deposited films and the technology of processing their surfaces. Data on the emission properties of materials can be obtained by means of experimental measurements or by calculation methods using molecular dynamics. In both cases, this is associated with significant resource costs. In the cases where some of these characteristics of the materials are unknown, a calibration procedure can be recommended to determine them. Details of this procedure are described in this paper. Comparison of numerical and experimental data for specific devices is performed.
