马歇尔掠射 X 射线光谱仪 (MaGIXS) 是一项拟议的探空火箭实验，旨在首次观察日冕的空间分辨软 X 射线光谱。该仪器采用纯掠入射设计，由一台 Wolter Type-1 扇形望远镜和一台狭缝摄谱仪组成。望远镜反射镜是一块整体式 Zerodur 反射镜，具有抛物面和双曲面。该光谱仪包括一对用作准直器和重成像镜的抛物面镜，以及一个平面变线距光栅，其反射面以 2 度的掠射角工作。这会在探测器上产生覆盖 6-24Å (0.5-1.2 keV) 波长范围的平坦光谱。该设计在 8 角分长的狭缝上实现了 20 mÅ 光谱分辨率（10 mÅ /像素）和 5 角秒空间分辨率（2.5 角秒 /像素）。该光谱仪目前正在制造为实验室原型。候选飞行望远镜镜子也在开发中。
The Marshall Grazing Incidence X-ray Spectrograph (MaGIXS) is a proposed sounding rocket experiment designed to observe spatially resolved soft X-ray spectra of the solar corona for the first time. The instrument is a purely grazing-incidence design, consisting of aWolter Type-1 sector telescope and a slit spectrograph. The telescope mirror is a monolithic Zerodur mirror with both the parabolic and hyperbolic surfaces. The spectrograph comprises a pair of paraboloid mirrors acting as a collimator and reimaging mirror, and a planar varied-line-space grating, with reflective surfaces operate at a graze angle of 2 degrees. This produces a flat spectrum on a detector covering a wavelength range of 6-24Å (0.5-1.2 keV). The design achieves 20 mÅ spectral resolution (10 mÅ /pixel) and 5 arcsec spatial resolution (2.5 arcsec / pixel) over an 8-arcminute long slit. The spectrograph is currently being fabricated as a laboratory prototype. A flight candidate telescope mirror is also under development.
