THE BERKELEY EXTREME AND FAR-ULTRAVIOLET SPECTROMETER (BEFS)

Welcome to the home page of the Berkeley Extreme and Far-Ultraviolet Spectrometer (BEFS), a project of the Space Astrophysics Group of the University of California, Berkeley. Designed for high-resolution spectroscopy in the far and extreme ultraviolet, BEFS flew in space twice, in 1993 and 1996. BEFS is part of ORFEUS, the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometers, a joint project of NASA and the German space agency.

BEFS spectra from both the 1993 and 1996 missions are now available from the Multimission Archive at STScI (MAST).
