1L04 Cavities 3 and 8 Tuners

20 hours 12 minutes ago
Log Number: 4518902Logbook(s): Entry Makers: kernsBody: 

Checked tuners on both cavities to insure they were performing correctly and then checked tuning upstairs and they are properly tuning and set to resonance with cart. Checked probe cable connectors also due to not having any gradient on cavity 8 yesterday when we finally had RF and OLT. Replaced the RFCM in cav.8 and hopefully get it back when we are back in RF permit. Techs: C. Kerns and A. Shenenberger.
