论文摘要
麦克风会导致腔体破裂。这项研究讨论了他在CMTF测试的16个1.3 GHz冷冻模块的麦克风，LCLS-II为14个，LCLS-II的麦克风。将讨论每个冷冻模块的峰值失调以及RMS的峰值。对于每个冷冻模块，数据都是在足够的浸泡时间中获取的，以防止任何可能在失调中显示的热效应。每个捕获的数据捕获为30分钟或更长时间，并以1 kHz采样。
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.
