Abstract
Expressions are obtained for the noise figure of the photoelectric image intensifier type of tube using a microchannel plate in the linear gain mode, including effects of dark current and ionic or optical feedback in the MCP, and of the same device using the MCP in an electron-counting mode. Comparison shows that the latter should be a preferable mode of operation, if practical problems can be overcome.
