We present a novel X-ray assembly of functionally related instrument blocks intended to measure solar flare and active region (AR) spectra from within the Russian instrument complex KORTES, to be mounted aboard the International Space Station (ISS). SolpeX consists of three blocks: fast-rotating multiple flat crystal Bragg spectrometer, pin-hole X-ray spectral imager and Bragg polarimeter. This combination of measuring blocks will offer an opportunity to detect/measure possible X-ray polarization in soft X-ray emission lines/continuum and record spectra of solar flares, in particular during their impulsive phases. Polarized Bremsstrahlung and line emission may arise from presence of directed particle beams colliding with denser regions of flares. As a result of evaporation, the X-ray spectral-components are expected to be Doppler shifted, which will also be measured. In this paper, we present details of the construction of three SolpeX blocks and discuss their functionality. Delivery of KORTES with SolpeX to ISS is expected in 2020/2021.

软 X 射线光谱仪旋光仪 SolpeX

我们展示了一种功能相关仪器块的新型 X 射线组件，用于测量俄罗斯仪器综合体 KORTES 内的太阳耀斑和活动区 (AR) 光谱，这些仪器将安装在国际空间站 (ISS) 上。SolpeX 由三个模块组成：快速旋转多平面晶体布拉格光谱仪、针孔 X 射线光谱成像仪和布拉格偏振仪。这种测量块的组合将提供一个机会来检测/测量软 X 射线发射线/连续谱中可能的 X 射线偏振，并记录太阳耀斑的光谱，特别是在它们的脉冲阶段。极化轫致辐射和线发射可能是由于定向粒子束与更密集的耀斑区域发生碰撞而引起的。由于蒸发，预计 X 射线光谱分量会发生多普勒频移，这也将被测量。在本文中，我们介绍了三个 SolpeX 模块的构造细节并讨论了它们的功能。预计 2020/2021 年将带有 SolpeX 的 KORTES 交付给国际空间站。
