Abstract

We will discuss our attempts to measure of the absolute gain and its variation across the face of fast gated multichannel plate [MCP] detectors for 4.75 keV x-rays. We found that some of the gated strips had variations in the gain along and perpendicular to the direction of travel, and significant variation along the time axis that requires these calibrations to obtain the correct time history of gated events. We will also present some of the results on the linearity of such gain with input x-ray signal amplitude.
