论文摘要
目前的贡献报告了在Fermilab的PIP-II项目框架中开发的预生产单辐谐振2型冷冻模块（PPSSR2 cm）的设计。创新的设计基于一个结构，即强力，该结构从底部支撑冷剂，在操作过程中保持在室温下，并且可以相对于真空容器纵向滑动。 Fermilab风格的冰冷模块为单辐谐振器1型（PSSR1）和原型高β650MHz（PHB650）Cryomodules开发的是当前设计的基线，它为生产SSR1和SSR2 Cryomodules提供了PIP-II Linac的生产方式。该贡献的重点是进行的计算结果和有限元分析的结果，以优化冷冻模块的临界成分：真空容器，强背，热屏蔽和磁性屏蔽。
The present contribution reports the design of the pre-production Single Spoke Resonator Type 2 Cryomodule (ppSSR2 CM), developed in the framework of the PIP-II project at Fermilab. The innovative design is based on a structure, the strongback, which supports the coldmass from the bottom, stays at room temperature during operations, and can slide longitudinally with respect to the vacuum vessel. The Fermilab style cryomodule developed for the prototype Single Spoke Resonator Type 1 (pSSR1) and the prototype High Beta 650 MHz (pHB650) cryomodules is the baseline of the current design, which paves the way for production SSR1 and SSR2 cryomodules for the PIP-II linac. The focus of this contribution is on the results of calculations and finite element analysis performed to optimize the critical components of the cryomodule: vacuum vessel, strongback, thermal shield, and magnetic shield.
