Theoretical Performance of a Multi-Order Spectral Imager for the Solar Transition Region
Abstract
The 2006 sounding rocket launch of the Multi-Order Solar EUV Spectrograph (MOSES) provided simultaneous imaging and spectroscopy of the solar atmosphere through the use of 3 projections provided by a concave reflection grating. A new, more flexible instrument design has been proposed that allows the use of 4-8+ projections to obtain higher moments of the spectral line profile in a configuration that also provides increased sensitivity and improved manufacturability. The optical performance of this instrument is investigated and optimized with respect to grating design parameters, and its scientific utility is discussed.
