Gain variation with gold coating thickness in pulsed microchannel plate striplines
Technical Report
·
OSTI ID:6958967
We have built and fielded gated stripline microchannel plate (MCP) detectors since 1984. We have always coated the input (stripline) side with 1 ..mu..m of gold, and the output or ground plane side with 1.5 ..mu..m of gold. It now appears that this input-side coating thickness is excessive, significantly reducing the gain obtainable from the detector. The strong gain reduction is correlated with slight closing up of the 12-..mu..m openings of the microchannels in the input side of the MCP. 4 refs., 7 figs.
