Abstract

The quantum detection efficiency of photon-counting microchannel-plate detector channels can be increased by a factor of 2 in the extreme ultraviolet bandpass, from 256 Å to 1024 Å, by subjecting the input channel plate to a chemical solution treatment. The efficiency increase has proven to be insensitive to the exposure of laboratory atmosphere and is stable over the extracted charge lifetime equivalent of multiyear astrophysical observations. Chemically treated microchannel plates that are overcoated with opaque photocathodes of KBr and CsI show a factor of 2 quantum detection efficiency increase from 834 Å to 1100 Å in comparison with previous measurements using conventional untreated microchannel plates.
