Paper Abstract

We present the results of the transmission calibrations of the seven sets of flight integration filters for the Extreme Ultraviolet Explorer satellite. Absolute transmissions have been determined over six orders of magnitude at 28 wavelengths using the Berkeley EUV Calibration Facility. Models for the filter transmission over the extreme ultraviolet wavelength range have been derived from these results and from calibrations of other test filters. Witness test filters composed of foils identical to the flight integration filters have also been calibrated as part of a lifetesting program. This program is designed to monitor changes in the transmission and mechanical properties of the EUVE filters over the life-time of the mission (assembly, launch and operation). Recent results from the lifetest filter calibrations are also presented, representing data accumulated over a four year period.
