位于拉帕尔马岛加那利群岛海拔2250米处、直径23米的CTA大型尺寸切伦科夫望远镜（LST）是继MAGIC、H.E.S.S.和VERITAS之后的下一代切伦科夫望远镜。为实现对伽马射线暴的快速定位（18秒内转动180度），其机械结构被设计为超轻量级（110吨）。该空间框架结构由碳纤维、铝（碟形天线及相机桅杆）和钢材制成的细长支柱构成。望远镜设计用于承受拉帕尔马岛ORM天文台的极端环境条件，包括高达200公里/小时的风速、上举力以及高达30吨的冰荷载。我们介绍了为满足这些功能和环境要求而开发的结构设计。慕尼黑MPP与法国合作伙伴机构（LAPP）、西班牙合作伙伴机构（IFAE）共同负责该望远镜的机械结构。原型机LST-1自2019年起投入运行，另有三台LST目前正在建造中。
英文摘要
The 23 m diameter Large Size Cherenkov Telescope (LST) for CTA, located at 2250 m a.s.l. on the Canary Island of La Palma, is the next-generation Cherenkov telescope following MAGIC, H.E.S.S., and VERITAS. To enable rapid repositioning (180° in 18 s) for gamma-ray burst observations, the mechanical structure was designed to be ultra- lightweight (110 tons). The space-frame structure consists of slender struts made of carbon fibre, aluminium (dish and camera mast), and steel. The telescope is designed to withstand extreme environmental conditions at the ORM observatory on La Palma, including wind speeds up to 200 km/h, uplift forces, and ice loads of up to 30 tons. We present the structural design developed to meet these functional and environmental requirements. MPP Munich is responsible for the telescope's mechanical structure together with partner institutes in France (LAPP) and Spain (IFAE). The prototype, LST-1, has been operational since 2019, and three additional LSTs are curre1ntly under construction.
