摘要:

目前的贡献报告的设计预生产单辐条谐振器2型低温(ppSSR 2 CM),在费米实验室的PIP-II项目的框架内开发。创新设计基于一种结构,即强力背板,它从底部支撑冷物质,在操作期间保持室温,并可以相对于真空容器纵向滑动。为原型单辐谐振器1型(pSSR 1)和原型高β 650 MHz(pHB 650)低温模块开发的费米实验室式低温模块是当前设计的基线,为PIP-II直线加速器生产SSR 1和SSR 2低温模块铺平了道路。这方面的贡献的重点是计算和有限元分析的结果进行优化的cryomoplant的关键部件:真空容器,定位板,热屏蔽,磁屏蔽。

英文摘要:

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.
