CED - Training (Work Smarter Presentation)
Network and IOC Power outage recovery in Hall B, W4 and W5
Put RF into Chopper 2X, 2Y and Buncher cavities. Incrementally adjusted the forward power to previous GSET levels while monitoring Chopper vacuum. Chopper 2X gave us a few minor burps on the way. Resonance adjustments are not yet optimized so we will continue tomorrow or Friday.
The panel upgrade for Bldg 87 (ACS) is complete. Let me know if there are any issues. We will begin Bldg 85 (MCC) tomorrow 12-11-25 after the 8am morning meeting. All doors will most likely be operational at the end of day 1. Day 2 we are planning to finish panel cleanup, labeling and testing.
Pre-job briefing held today in the injector with K. Jordan and J. Carucci. I submitted it to the management discussions portal, assigned # 12945. See attachment.
Upcoming tasks:
12/11: Jessica with move the chiller from LERF to ISB using a liftgate pick-up truck. She will also clean up the V-Wien magnet yoke.
12/12: Jessica will crane the chiller down to the injector using the ISB monorail crane. I will be her spotter.
12/12: Kevin will install V-Wien cooling plates. I will assist as needed. He has the rubber hoses laid out with all the fittings.
Many thanks to P.
In preparation for EM power being cut off in the South Linac tomorrow: https://tasklists.jlab.org/atlis/tasks/117885.
Ion pump power supplies have been temporarily connect to house power.
The following zones were moved:
2L02, 2L04, 2L05.
The following Turbo pumps were moved:
2L07 and 2L08.
Vacuum group will need scroll pumps to house power in the following zones downstairs:
2L07, 2L08 and 2L09.
We did our check list, turned off the ion pumps and started to flow gas. The ion pump at 1L11B tripped off at about 20 mTorr in 1L10. VIP1L11B was on the other side a closed beam line valve and it also has a turbo pumping on the ion pump. It tripped at 4e-6 Torr. We turned off the mass flow and stepped back. Pausing and seeking advice is a contingency that was in the procedures for just such an event.
Apparently the VBV1L11A has a massive leak. Frank Humphry and I discussed some options about what we might do. One of those options is that we do not process 1L10.
