摘要：

We describe electronics developed for the operation of multianode microchannel plate (MCP) photomultipliers in a multipoint Thomson scattering system. A pulsed, digitally programmable high voltage power supply with current feedback and a built-in protection circuit has been designed to bias the detector in safe conditions, taking into account the nonlinear behavior of the MCP resistance. The 180-V photocathode voltage is switched by a fast, current driven, optically coupled metal-oxide-semiconductor field-effect transistor. Gating pulses with 10-ns rise time and 50-500-ns programmable duration are generated with negligible noise at the output anodes.
