AI 中文摘要
直径23米的大型望远镜（LST）是下一代切伦科夫望远镜阵列（CTA）中尺寸最大的望远镜。首台望远镜LST-1于2018年安装在拉帕尔马岛的罗克德洛斯穆查乔斯天文台（ORM），海拔2250米，自2019年起投入运行。其超轻结构（110吨）可实现极快的重新定位（18秒内旋转180°），并设计为可承受极端环境条件，包括风暴和超过200公里/小时的风速。为将相同的固体望远镜设计部署到智利的CTA南方天文台，该结构必须适配场地显著更高的地震需求。为应对这一挑战，马克斯·普朗克物理研究所（MPP）提出在经过验证的LST-1结构设计中集成隔震系统。这种方法大幅降低了地震荷载和动力放大效应，从而避免了大规模结构修改，使现有望远镜设计仅需微小调整即可转移至智利场地。在本研究中，我们介绍了所提出的隔震概念及其可行性研究。MPP负责LST的机械结构，并通过详细的有限元分析和长期结构寿命评估验证了该概念。
英文摘要
The 23-meter-diameter Large-Sized Telescope (LST) is the largest size telescope of the next generation Cherenkov Telescope Array (CTA). The first telescope, LST-1, was installed at the Roque de los Muchachos Observatory (ORM) on La Palma at an altitude of 2,250 m in 2018 and has been in operation since 2019. Its ultra-lightweight structure (110 tons) enables extremely rapid repositioning (180° in 18 seconds) and has been designed to withstand extreme environmental conditions, including storms and winds exceeding speed up to 200 km/h. To deploy the same solid telescope design at the CTA Southern Observatory in Chile, the structure must be adapted to the significantly higher seismic demands of the site. To address this challenge, the Max Planck Institute for Physics (MPP) has proposed the integration of a seismic isolation system with the proven LST-1 structural design. This approach substantially reduces seismic loads and dynamic amplification, thereby avoiding extensive structural modifications and enabling the existing telescope design to be transferred to the Chilean site with only minor adaptations. In this contribution, we present the proposed seismic isolation concept and its feasibility studies. MPP is responsible for the mechanical structure of the LST and has validated the concept through detailed finite-element analyses and long-term structural lifetime assessments.
