Abstract
A method for regulating a signal level in a power supply for a microchannel plate in a radiation detector is provided. The method includes receiving an input signal at a signal multiplier. The signal multiplier has an output terminal and a return terminal. An output signal is produced at the output terminal. The output signal is provided to the microchannel plate. A regulation signal is provided from the output terminal to the return terminal. A signal level of the output signal is regulated with the regulation signal.
