摘要

麦克风会导致腔体失谐。本文讨论了在CMTF测试的16个1.3 GHz低温模块的传声器，其中LCLS-II低温模块14个，LCLS-II低温模块2个。将讨论每个低温模块的峰值失谐以及均方根失谐。对于每个低温模块，数据是在足够的浸泡时间内获取的，以防止任何可能在失谐中出现的热化效应。每次数据捕获时间为30分钟或更长，采样频率为1 kHz。

LCLS-II AND HE CRYOMODULE MICROPHONICS AT CMTF IN FERMILAB

Microphonics causes the cavity to detune. This study discusses the microphonics of sixteen 1.3 GHz cryomodules, 14 for LCLS-II and 2 for LCLS-II HE tested at CMTF. The peak detuning, as well as the RMS detuning for each cryomodule, will be discussed. For each cryomodule, the data was taken with enough soaking time to prevent any thermalization effects which can show up in the detuning. Each data capture taken was 30 minutes or longer and sampled at 1 kHz.
