Development of a Slitless Spectrograph for X-Ray Astronomy
Published online by Cambridge University Press: 06 March 2019
Abstract
The soft x - ray slitless spectrograph is described, and its usefulness in making rapid surveys of wide spectral regions is discussed Fabrication of the 1μ thick gold-shadowed transmission gratings used in the instrument is described. Spectra taken in the laboratory and during a solar sounding rocket flight are presented. Because a simple absorbing strip model is inadequate to explain the distribution of intensities among the spectral orders, a phase-grating model must be adopted.
