Abstract

After shipment to the Daresbury Lab and return to Fermilab, the prototype HB650 cryomodule underwent another phase of 2K RF testing to ascertain any performance issues that may have arisen from the transport of the cryomodule. While measurements taken at room temperature after the conclusion of shipment indicated that there were no negative impacts on cavity alignment, beamline vacuum, or cavity frequency, testing at 2K was required to validate other aspects such as tuner operation, cavity coupling, cryogenic system integrity, and cavity performance. Results of this latest round of limited 2K testing will be presented.

跨大西洋运输后 PIP-II 高贝塔 650 冷冻模块的性能

原型 HB650 低温模组在运往达雷斯伯里实验室并返回费米实验室后，又进行了另一阶段的 2K 射频测试，以确定低温模组在运输过程中可能出现的任何性能问题。运输结束后在室温下进行的测量表明，空腔对准、波束线真空或空腔频率没有受到负面影响，但仍需要进行 2K 测试，以验证调谐器运行、空腔耦合、低温系统完整性和空腔性能等其他方面。将介绍最新一轮有限 2K 测试的结果。
