Abstract

An extreme ultra-violet diffuse spectrograph known as the ultraviolet cosmic background spectrometer is scheduled for a 1996 launch on the NASA SSTI mission Lewis. UCB is one of three prime science instruments aboard the Lewis spacecraft and is schedules to conduct observations for 3 to 5 years. The spectrograph will obtain spectra of diffuse 550 to 1100 angstrom radiation with a sensitivity improvement of an order of magnitude or more in comparison with previous work. UCB incorporates new technology such as a special diffraction grating, an anti-coincidence guarded micro- channel plate detector system, low-radioactivity ultra low- noise micro-channel plates, and a chemical treatment for enhancing detector efficiency. The observations will contribute important new information about the Galaxy's local interstellar medium and about speculative scenarios regarding exotic nuclear particles in dark matter. We describe the instrumentation and the UCB science mission.
