Currently, RF believes they have isolated the issue to cavity 5, but still cannot find the leak. In discusson with RF and SSG group leaders, the staffing is not available to lock out the zone and plate out the waveguides. We do not have enough headroom to bypass the zone (currently have 23 MeV of headroom w 1L12, but 37 MeV in the zone). We are unfortunately unable to run tonight.

The leak has been isolated to 1L12-5 but no source of the leak can be seen upstairs. New tubing has been fabricated and attached but has not resolved the issue. Workers used Spotter to aid leak detection but could find no source of the leak upstairs. Both workers have been on the job as long as is allowed so work is being paused until morning when more support will be available.
