  Mi­cro­phon­ics causes the cav­ity to de­tune. This study dis­cusses the mi­cro­phon­ics of 16 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.
