本贡献报告了预生产单辐条谐振器类型 2 冷冻模块 (ppSSR2 CM) 的设计，该设计是在费米实验室 PIP-II 项目框架下开发的。该创新设计基于一种结构，即强背板，该结构从底部支撑冷体，在操作过程中保持在室温，并且可以相对于真空容器纵向滑动。为原型单辐条谐振器类型 1 (pSSR1) 和原型高 Beta 650 MHz (pHB650) 低温模块开发的 Fermilab 型低温模块是当前设计的基线，为 PIP-II 直线加速器的生产 SSR1 和 SSR2 低温模块铺平了道路。本贡献的重点是为了优化低温模块的关键部件而进行的计算和有限元分析的结果：真空容器、强力背板、热屏蔽和磁屏蔽。
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.
