Unit test completed. CED parameters pushed - should bo good for LEM / General use. Cav. 2 may need to be derated on a 2-day time scale for cold IR faults (CWWT) from 16.5. The interlock trip point is already set to 4V.

2L25-2 derated a few times for cold IR sensor; some of the heat load limited cavities were biased very slightly to make up for the gradient. Zone at 95.2 MeV following unit test completion.

Turning zone off; SWlist 120408 going in to merge parameters into CED Ops workspace now.

Coordinated w/ ops to turn off RF in the SL. Plumbed in couplers to monitor SL MO signals without disturbing ops. Notified that I was done and that RF could turn RF back on in the South.

A lot of cavities in the SL started showing GLDER and PLDER alarms. RF suspects MO. We turned off RF in the SL to support that work.
