AI 中文摘要
全球轨道软X射线偏振计（GOSoX）是一款用于软X射线波段的分光偏振计，基于NASA资助的探空火箭有效载荷——软X射线偏振计火箭实验演示（REDSoX）研发。与REDSoX类似，GOSoX包含NASA马歇尔太空飞行中心（MSFC）研制的Wolter I型X射线光学组件、麻省理工学院（MIT）制造的临界角透射（CAT）光栅，以及劳伦斯伯克利国家实验室（LBNL）制备的用于X射线偏振的多层（ML）涂层反射镜。图宾根大学（U. Tübingen）的团队将为焦平面适配商用sCMOS传感器。光栅色散与设置为45°的多层反射镜的横向分级相匹配，GOSoX可在0.2-0.4 keV全波段测量偏振，光谱分辨率E/dE约为100；预计在为期一年的任务中，可对十余个目标实现3%-10%的最小可检测偏振（MDP），该任务已被NASA选定，计划于2030年发射。
英文摘要
The Globe Orbiting Soft X-ray Polarimeter (GOSoX) is a spectropolarimeter for the soft X-ray band. GOSoX is based on the Rocket Experiment Demonstration of a Soft X-ray Polarimeter (REDSoX), a NASA-funded sounding rocket payload. Like REDSoX, GOSoX consists of Wolter I X-ray optics from NASA/MSFC, critical-angle transmission (CAT) gratings made at MIT, and multilayer (ML) coated mirrors from LBNL that polarize the X-rays. Colleagues at U. Tübingen will adapt commercially available sCMOS sensors for the focal plane. The grating dispersion is matched to the lateral grading of ML mirrors set at 45°. GOSoX can measure polarization across the entire 0.2-0.4 keV band with a spectral resolution E/dE $\sim$100. Minimum detectable polarizations (MDPs) of 3-10\% are expected for over a dozen targets in a one-year mission. The mission was selected by NASA for launch in 2030.
