Abstract

Sounding rocket observations of G191-B2B are planned for 1999 January over the bandpass 256-304 angstrom with a high resolution spectrograph. The optical system implements two diffraction gratings with broadband multilayer coatings in a Wadsworth mount. Since the spectral resolution of the experiment will be signal limited, preliminary reflectivity test on test gratings have been performed to determine how high the resolution might be.
