Paper Abstract

We describe a gated microchannel plate (MCP) based Quantitative X-ray Imager (QXI) developed by Los Alamos National Laboratory (LANL) and measure some of its performance characteristics. Such imagers use propagating electrical pulses along microstrips on the MCP to quickly gate on and off portions of the strip and hence provide fast framing capability (typically 100 ps frames with up to 1 ns time coverage). Three issues have been quantitatively studied using the QXI and another similar but older LANL gated x-ray framing camera, the GXI-T: QXI pulse shapes generated by its pulse-forming modules: GXI-T optical pulse widths as a function of incident UV energy on the microchannel plate: and the modulation transfer function (MTF) of the QXI intensifier.
