The parameters of a herringbone microchannel amplifier are studied as functions of the input signal intensity and the size of the microchannel-plate (MCP) working zones, i.e., the number of actually functioning channels. The sensitivity of the microchannel amplifier to overloads was found to be the higher, the greater the number of functioning channels, and the maximum count rate at the output of a single channel was obtained with the smallest MCP working-zone area (in this case, the channel dead time was similarly ordered 0.3 msec). The dead times of the individual channels can vary according to the irradiation conditions, which allows considerable expansion of the sensitivity dynamic range by changing the dimensions of the MCP input surface with variation of the input signal intensity.
