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 ( λ Δλ ≳ 7000) 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.
