摘要
尽管极大型望远镜在UV/光学/NIR波段已然出现，当前一代8-10米设施在可预见的未来于地基紫外波长上仍可能保持竞争力。卡塞格林U波段高效光谱仪（CUBES）被设计用于在近紫外（305-400 nm为要求，300-420 nm为目标）以高于20,000的光谱分辨本领提供高效率（>40%）观测，尽管也计划了 R~7,000 的较低分辨率、受天空限制的模式。CUBES将在天体物理诸多领域提供新可能，可获取恒星光谱关键谱线：极为多样的铁峰与重元素、较轻元素（特别是铍）及轻元素分子（CO、CN、OH），以及巴耳末线和巴耳末跳变（对年轻恒星天体尤为重要）。紫外波段在河外研究中亦关键：遥远星系的环星系介质、不同源类对宇宙紫外背景的贡献、在相对透明星系际介质 regime 下 H2 与原始氘的测量，以及爆发暂现源的后续观测。CUBES项目于2021年6月完成A阶段概念设计，现已进入致力于详细设计与建造的B阶段。首次科学观测计划于2028年。本文中，我们简要描述CUBES项目的发展与目标、主要科学案例、仪器设计以及项目组织与管理。
