Abstract

The Lunar Environment heliospheric X-ray Imager (LEXI) is a wide field-of-view soft X-ray telescope developed to study solar wind-magnetosphere coupling. LEXI is part of the Blue Ghost 1 mission comprised of 10 payloads to be deployed on the lunar surface. LEXI monitors the dayside magnetopause position and shape as a function of time by observing soft X-rays (0.1-2 keV) emitted from solar wind charge-exchange between exospheric neutrals and high charge-state solar wind plasma in the dayside magnetosheath. Measurements of the shape and position of the magnetopause are used to test temporal models of meso- and macro-scale magnetic reconnection. To image the boundary, LEXI employs lobster-eye optics to focus X-rays to a microchannel plate detector with a 9.1 ${}^{\circ}\times {9.1}^{\circ}$ field of view.

月球环境太阳物理学 X 射线成像仪（LEXI）任务。

月球环境日光层 X 射线成像仪（LEXI）是为研究太阳风-磁层耦合而开发的宽视场软 X 射线望远镜。LEXI 是蓝幽灵 1 号任务的一部分，由 10 个有效载荷组成，将部署在月球表面。LEXI 通过观测外大气层中性物质和日侧磁鞘中高电荷态太阳风等离子体之间太阳风电荷交换发出的软 X 射线（0.1-2 千伏），监测日侧磁鞘位置和形状随时间的变化。对磁层顶形状和位置的测量用于检验中尺度和大尺度磁重联的时间模型。为了对边界进行成像，LEXI 采用了龙虾眼光学技术，将 X 射线聚焦到具有 9.1×∘9.1∘ 视场的微通道板探测器上。

期刊介绍： Space Science Reviews (SSRv) stands as an international journal dedicated to scientific space research, offering a contemporary synthesis across various branches of space exploration. Emphasizing scientific outcomes and instruments, SSRv spans astrophysics, physics of planetary systems, solar physics, and the physics of magnetospheres & interplanetary matter. Beyond Topical Collections and invited Review Articles, Space Science Reviews welcomes unsolicited Review Articles and Special Communications. The latter encompass papers related to a prior topical volume/collection, report-type papers, or timely contributions addressing a robust combination of space science and technology. These papers succinctly summarize both the science and technology aspects of instruments or missions in a single publication.
