“…A large number of articles have been published on both theoretical (e.g., [5][6][7]) and experimental studies (e.g., [8,9]) of glass microchannel plates, widely used in image intensified and night vision devices. However, the fabrication of similar devices with lithographic precision and their operation in deep saturation as a controlled source of electron beams has not been fully explored.…”

“…In most detection applications, the intensity of amplified signal should be proportional to the intensity of incoming signal, while the MCA output should be very stable and uniform across the entire array. The latter distinction allows for the operation of the MCA in, or near, deep saturation, while in most detection devices the saturation of the output signal of channel electron amplifiers has to be avoided [5,6,8].…”

“…Amplification of input signals in microchannel electron amplifiers is a complicated stochastic process, which is usually simulated by the use of Monte Carlo (MC) methods ( [1][2][3][4]9,11]). However, the direct simulation of the entire amplification process by the MC methods require considerable computer time (for example, see [5]), especially for optimization problems.…”

Electron-optical devices with microchannel amplification have many advantages, except poor noise characteristics. In order to increase gain and reduce a noise factor a layer with increased secondary emission is deposited on the top of a contact conducting layer at the entrance of channels. Effects, arising in the channel amplifier with the high-efficiency emitter, are investigated in this work using the computational method, developed by the author. A computational method for simulation of stochastic processes of an electron multiplication is based on 3D Monte Carlo simulations and the theorems of serial and parallel amplification stages proposed by the author. The method provides a high calculation accuracy with minimal cost of computations. The computational model is used to investigate the effect on the noise factor of the incidence angle of the input electron beam, nonuniformity of the emitter surface, the depth and secondary emission yield of the high-efficiency emitter.Keywords Microchannel electron amplifier · Monte Carlo simulations · Nonuniformity of an emitter surface · High-efficiency emitter · Noise factor
