AbstractThe Space Astrophysics Group is currently fabricating a novel EUV spectrometer for the ORFEUS-SPAS mission. It uses a set of four varied line-space spherical diffraction gratings to obtain high resolution () spectra of point sources at wavelengths between 390 and 1200 Å. The spectra are recorded with two detector units, each containing curved surface microchannel plates and a delay-line anode readout system. An independent optical system detects the image of the source in the entrance aperture and tracks the source as it drifts during an observation, enabling a reconstruction of the spectra postflight. The overall system performance is discussed and illustrated by synthetic spectra.
