技術研修会「シミュレーション技術」　SuperKEKB最終収束用超伝導電磁石システム（QCS）の設計とシミュレーション手法

抄録

SuperKEKB is an electron-positron collider at the High Energy Accelerator Research Organization (KEK), which aims for a peak luminosity of 8.0×10³⁵ cm^－2 s^－1. In order to realize this high luminosity, the beam size at the interaction point is squeezed to ~50 nm in the vertical direction by the final focusing superconducting magnet system (QCS).When designing the QCS system, 3D simulation and optimization of the support system were carried out given the presence of external magnetic field and vibration. The simulation results were compared with measurements. In this paper, some examples of simulation results, such as structural analysis and vibration analysis are shown.
