Description
The experience of computer-aided design of micro channel amplifiers as fast photo detectors of modern charged particle accelerators is generalized. All aspects of the design of devices from the photo cathode to the collector are considered, including the issues of thermal stability, the influence of noise, saturation effects, the influence of edge fields, dark currents and the operation of amplifiers in strong magnetic fields. A review is given of modern analytical, numerical and mixed mathematical models used in modeling amplifiers that detect signals in a wide range of radiation - from infrared to x-ray. Comparison of simulation results with experimental data for four major Russian and foreign projects in which the author participated.
