本文介绍Aditya-L1任务搭载的HEL1OS硬X射线光谱仪的调试、数据处理流程及观测数据，验证其可用于太阳X射线波段的时序与光谱监测。
AI 中文摘要
HEL1OS（高能L1轨道X射线光谱仪）是Aditya-L1太阳任务搭载的硬X射线光谱仪，在日地拉格朗日L1点（L1）的有利观测平台上，持续监测8 keV至150 keV硬X射线波段的太阳。HEL1OS于2023年10月底完成调试，2024年6月底完成所有性能验证后确定最终仪器配置。该仪器始终以事件模式运行，下传的数据通过自动化流水线处理，生成科学级产品，主要包括8 keV至150 keV能量波段的太阳光谱。2023年12月以来的观测数据（包括有效载荷运行性能验证阶段的数据）已在互联网上公开访问。本文讨论了调试与性能验证阶段的细节、全自动化数据流水线的所有阶段，以及HEL1OS的数据产品，还讨论了部分科学结果，以说明该仪器在X射线波段监测太阳的时序与光谱能力。
英文摘要
HEL1OS (High Energy L1 Orbiting X-ray Spectrometer) is the hard X-ray spectrometer on-board Aditya-L1 solar mission, monitoring the Sun continuously in the hard X-ray band of 8 keV to 150 keV from the vantage observation platform around the Sun-Earth Lagragian Point 1 (L1). HEL1OS was commissioned in end of October, 2023 and the final instrument configuration was set by end of June, 2024 after all the performance verifications. The instrument always operates in the event mode, and the down-linked data is processed in an automated pipeline to generate Science-ready products comprising mainly of solar spectra in 8 keV to 150 keV energy band. The data products of observations since December, 2023 are hosted on the internet with open access. This includes data from the performance verification phase of the payload operations. In this paper, the details of the commissioning and performance verification phases, all the stages of the fully automated data pipeline, and the data products of HEL1OS are discussed. Also a few scientific results are discussed to illustrate the timing and spectral capabilities of the instrument in monitoring Sun in the X-ray energy bands.
