介绍了用于甚大望远镜的卡塞格伦U波段高效摄谱仪（CUBES）的基本概念设计。CUBES将为地面紫外线（UV）中8 - 10米级望远镜的光谱学提供前所未有的灵敏度，跨越≥ 100 nm的带宽，从300 nm开始，这是从地面可以到达的最短波长。该设计已针对端到端效率进行了优化，并提供了R ≥ 20000的光谱分辨率，这将开启太阳系，银河系和银河系外天文学的广泛新课题。该设计还具有第二个，低分辨率（R7000）模式，并有一个光纤连接到UVES仪器的选项，同时在更长的波长observations.Here我们提出的光学，机械和软件设计的仪器的各个子系统后，A阶段的研究项目。我们讨论了布局选择的预期性能，并强调了一些性能权衡考虑，以最好地满足仪器的顶级要求。我们还介绍了基于模型的系统工程方法，用于组织和管理项目活动和接口，在这种情况下，越来越有必要将这些工具集成在复杂的天文项目的发展。
We present the baseline conceptual design of the Cassegrain U-Band Efficient Spectrograph (CUBES) for the Very Large Telescope. CUBES will provide unprecedented sensitivity for spectroscopy on a 8 – 10 m class telescope in the ground ultraviolet (UV), spanning a bandwidth of ≥ 100 nm that starts at 300 nm, the shortest wavelength accessible from the ground. The design has been optimized for end-to-end efficiency and provides a spectral resolving power ofR≥ 20000, that will unlock a broad range of new topics across solar system, Galactic and extraglactic astronomy. The design also features a second, lower-resolution (R7000) mode and has the option of a fiberlink to the UVES instrument for simultaneous observations at longer wavelengths.Here we present the optical, mechanical and software design of the various subsystems of the instrument after the Phase A study of the project. We discuss the expected performances for the layout choices and highlight some of the performance trade-offs considered to best meet the instrument top-level requirements. We also introduce the model-based system engineering approach used to organize and manage the project activities and interfaces, in the context that it is increasingly necessary to integrate such tools in the development of complex astronomical projects.
