我们提出了一个新的空间观测太阳物理学的仪器，最近成功地在探空火箭上飞行，旨在提供高空间分辨率，时间分辨图像的太阳日冕在特定波长的极紫外线（XUV）。主要仪器采用多层X射线镜在一个新的几何形状，提供准单色成像的波长可调连续光谱范围从17.1到21.1纳米。辅助仪器还使用多层X射线镜，在三个固定的XUV波段提供高分辨率成像。这两种仪器都使用电荷耦合器件检测器和薄A1滤波器来抑制不需要的波长。我们描述了仪器的设计，结构和性能，并讨论了未来的前景。
We present a new instrument for space-based observational solar physics, recently flown successfully on a sounding rocket, designed to provide high spatial resolution, time-resolved images of the solar corona at specific wavelengths in the extreme ultraviolet (XUV). The primary instrument employs multilayer x-ray mirrors in a novel geometry that affords quasi-monochromatic imaging at wavelengths tunable continuously over the spectral range from 17.1 to 21.1 nm. The secondary instrument also uses multilayer x-ray mirrors to provide high-resolution imaging at three fixed XUV wavelength bands. Both instruments use charge coupled device detectors and thin A1 filters for rejection of unwanted wavelengths. We describe the design, construction, and performance of the instrument and discuss prospects for the future.
