Abstract

The FUSE (Far Ultraviolet Spectroscopic Explorer) instrument includes two large-format microchannel plate detectors with double delay line anodes. The generally good detector performance has permitted the collection of scientific data with high spectral resolving power, and has enabled the observation of fainter objects than could be easily observed with previous missions in this wavelength range. As with any complex instrumentation, however, there have been numerous challenges which have arisen during the mission. We discuss the on-orbit performance of the FUSE detectors since launch, and describe some of the lessons learned. This includes a discussion of their operation on orbit and the effects that detector performance has had on the scientific data collected. The strategies taken to minimize the impact of detector anomalies on the data will also be discussed.
