软X射线偏振计火箭实验演示装置（REDSoX）是NASA资助的探空火箭任务，其有效载荷将测量0.2-0.4 keV波段的偏振强度和方向，为IXPE在2-8 keV波段的测量提供补充。计划于2028年进行的首次飞行将对该偏振计概念进行技术演示，该概念采用聚焦光学系统、临界角透射（CAT）光栅、横向梯度多层（LGML）反射镜以及电荷耦合器件（CCD）探测器的对准系统来测量偏振。本文将介绍该仪器在关键设计评审后的设计、飞行硬件测试状态以及有效载荷组装情况。
英文摘要
The Rocket Experiment Demonstration of a Soft X-ray Polarimeter (REDSoX) is a NASA-funded, sounding rocket mission. The rocket payload will measure polarization strength and direction as a function of energy in the 0.2-0.4 keV band, providing complementary measurements to those made by IXPE in the 2-8 keV band. The first flight, scheduled for 2028, will provide a technology demonstration of our polarimeter concept, which utilizes an aligned system of a focusing optic, Critical-Angle Transmission (CAT) gratings, Laterally Graded Multilayer (LGML) mirrors, and Charge Coupled Device (CCD) detectors to measure polarization. We will describe the design of the instrument post-critical design review, the status of flight hardware testing, and payload assembly.
