聚焦光学x射线太阳成像仪（FOXSI）探空火箭有效载荷于2014年12月11日第二次飞行。为了实现直接硬x射线（HXR）成像光谱，FOXSI利用掠入射复制聚焦光学与细间距固体探测器相结合。FOXSI的第一次飞行提供了第一张HXR聚焦的太阳图像。对于FOXSI的第二次飞行，对仪器进行了几次更新，包括更新光学和探测器，以及增加一个新的太阳面向和对准系统（SAAS）。本文概述了这些更新，并讨论了它们的测量性能。
The Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket payload flew for the second time on 2014 December 11. To enable direct Hard X-Ray (HXR) imaging spectroscopy, FOXSI makes use of grazing-incidence replicated focusing optics combined with fine-pitch solid-state detectors. FOXSI's first flight provided the first HXR focused images of the Sun. For FOXSI's second flight several updates were made to the instrument including updating the optics and detectors as well as adding a new Solar Aspect and Alignment System (SAAS). This paper provides an overview of these updates as well as a discussion of their measured performance.
