AI 中文摘要
第5阶段光谱实验（Spec-S5）是下一代全天光谱设备，旨在解决宇宙学与天体物理学的基础问题。它依托暗能量光谱仪（DESI）的遗产，将两台现有4米望远镜升级为6米宽视场天文台，每台配备可同时测量13000条光谱的高复用摄谱仪。本文概述该项目的科学动机、系统架构与集成策略，Spec-S5将使光谱能力提升10倍以上，在鲁宾望远镜、DESI之后的时代实现变革性巡天，推进人类对暗物质、暗能量及宇宙结构形成的理解。
英文摘要
The Stage-5 Spectroscopic Experiment (Spec-S5) is a next-generation, all-sky spectroscopic facility designed to address fundamental questions in cosmology and astrophysics. Building on the legacy of the Dark Energy Spectroscopic Instrument (DESI), Spec-S5 will upgrade two existing 4-m telescopes into 6-m, wide-field observatories, each equipped with a highly multiplexed spectrograph capable of measuring 13,000 spectra simultaneously. This overview paper summarizes the science motivation, system architecture, and integration strategy of the project. Spec-S5 will deliver a more than tenfold increase in spectroscopic capability, enabling transformative surveys in the post-Rubin, post-DESI era and advancing our understanding of dark matter, dark energy, and cosmic structure formation.
