The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)

We present a novel design for a stigmatic grazing incidence X-ray spectrograph for flight on a NASA sounding rocket. MaGIXS is comprised of a Wolter I telescope, a slit, a pair of parabolic mirrors, a plano variable line-spaced grating and a CCD detector. This design and layout have been optimized to produce an optical system with peak effective area of 5 mm^2, a wavelength range of 0.6-2.4 nm, spectral resolution of 2.0 pm, and spatial pixels of 2.5 arcsec along a 5 arcminute slit. The resulting instrument will resolve the solar spectrum for features in the solar corona with a two orders of magnitude increase over previous soft x-ray spectrographs in spatial and spectral resolution.
