论文摘要
Linac Coolent Light Source（LCLS）是SLAC国家加速器实验室的X射线科学设施。 LCLS-II项目（对LCLS的升级）处于调试阶段； LCLS-II-HE（高能量）项目是该设施的另一次升级，从而实现了更高的能源运行。使用内置在冷冻模块中的超导射频（SRF）腔加速电子束。计划为LCLS-II-HE项目构建24 1.3 GHz标准的冷冻模块和一个1.3 GHz单腔束捕获腔（BCC）凝聚器。计划在费米拉布（Fermilab）组装和测试这些标准的冷冻模块中的14个和BCC。标准冷冻模块组件的采购接近完成。在Fermilab组装并测试了第一个LCLS-II-HE冻模，称为验证冷冻模块（VCM）。费米拉布（Fermilab）完成了第二个冷冻模块的组装。本文介绍了Fermilab的LCLS-II-He-II-he Cryomodule生产状态，强调了基于从LCLS-II汲取的成功，挑战，缓解和经验教训所做的变化；通过出色的VCM结果验证更改。
The Linac Coherent Light Source (LCLS) is an X-ray science facility at SLAC National Accelerator Laboratory. The LCLS-II project (an upgrade to LCLS) is in the commissioning phase; the LCLS-II-HE (High Energy) project is another upgrade to the facility, enabling higher energy operation. An electron beam is accelerated using superconducting radio frequency (SRF) cavities built into cryomodules. It is planned to build 24 1.3 GHz standard cryomodules and one 1.3 GHz single-cavity Buncher Capture Cavity (BCC) cryomodule for the LCLS-II-HE project. Fourteen of these standard cryomodules and the BCC are planned to be assembled and tested at Fermilab. Procurements for standard cryomodule components are nearing completion. The first LCLS-II-HE cryomodule, referred to as the verification cryomodule (vCM) was assembled and tested at Fermilab. Fermilab has completed the assembly of the second cryomodule. This paper presents LCLS-II-HE cryomodule production status at Fermilab, emphasizing the changes done based on the successes, challenges, mitigations, and lessons learned from LCLS-II; validation of the changes with the excellent vCM results.
