ABSTRACT
The microchannel plate, delay line, detectors developed for the Far Ultraviolet Spectroscopic Explorer1
mission to be launched in 1998 are described. The two FUSE detectors have a large format (·184mm x 10mm
split into two 88.5 x 10mm segments), with high spatial resolution (9000 x 200
resolution elements) and good linearity (±25µm), high image stability, and counting rates in excess of 4 x 104
events sec-1. KBr opaque photocathodes have been employed to provide quantum detection efficiencies of 30-
40% in the 900 - 1200Å range. Microchannel plates with 10µm pores and an 80:1 pore length to diameter ratio,
with a 95mm x 20mm format have been used in a Z stack configuration to provide the photon amplification (gain
· 2 x 107). These show narrow pulse height distributions (
