Abstract

The Low Energy X-ray telescope (LE) is one of the main instruments of the Insight-Hard X-ray Modulation Telescope (Insight-HXMT), the first Chinese X-ray astronomical satellite. The scientific objectives of LE focus on scanning and pointed observations of the X-ray sources in the soft X-ray band (0.7–13 keV). LE consists of three detector boxes (LEDs) and an electric control box (LEB). The LEB is composed of data handling unit, monitoring unit, and power distribution unit, with functions including data processing, communication, monitoring, power supply, and distribution. All the functions designed in the LEB were verified during the operation in orbit. To improve the efficiency of astronomical observations and reliability of LE, onboard data processing is designed in the LEB. The results of onboard data processing are immediately transmitted to the ground as important housekeeping data and are verified by comparing them with the processing results of the data transmitted to the ground. In the six years since launch, the LEB has performed well, operated smoothly, and met all expected requirements. The LEB has participated in numerous scientific observations, transmitted a large amount of scientific data, and obtained several observational results.

设计并验证 Insight-HXMT 上低能 X 射线望远镜的电控箱

低能 X 射线望远镜（LE）是中国首颗 X 射线天文卫星 Insight-硬 X 射线调制望远镜（Insight-HXMT）的主要仪器之一。低能 X 射线望远镜的科学目标主要是对软 X 射线波段（0.7-13 千伏）的 X 射线源进行扫描和指向观测。LE 由三个探测器箱（LED）和一个电控箱（LEB）组成。LEB 由数据处理单元、监控单元和配电单元组成，功能包括数据处理、通信、监控、供电和配电。LEB 设计的所有功能都在轨道运行中得到了验证。为了提高天文观测的效率和 LE 的可靠性，在 LEB 中设计了星载数据处理。星载数据处理的结果作为重要的内务数据立即传送到地面，并通过与传送到地面的数据处理结果进行比较来验证。自发射以来的六年中，LEB 表现出色，运行平稳，达到了所有预期要求。LEB 参与了多次科学观测，传输了大量科学数据，并取得了多项观测成果。

期刊介绍： Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Furthermore, a vast amount of effort is being put into the development of new techniques for data analysis in order to cope with great streams of data collected by these instruments. Experimental Astronomy acts as a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields. Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.
