The Berkeley spectrometer aboard the ORFEUS payload achieved a variety of “firsts” during its inaugural mission in September 1993. The instrument utilizes spherical gratings with mechanically ruled varied line-spacing, and curved microchannel plate detectors with delay-line anode readout systems, to cover the 390 – 1200 Å band at a resolution of λ/5000. The instrument will be discussed, and its performance illustrated with calibration and in-flight spectra. Science highlights from the ORFEUS-I mission will be presented (oral presentation only). The payload will be available for use by guest investigators during the ORFEUS-II mission currently scheduled for late 1996.
