MSSG relayed that they completed NLSB BoxPS flushing (Dog1E) and will proceed with flushing the two supplies (TSB5C, TAG5C) in the the Tagger ServBldg (B200) tomorrow, Friday 11/6.

For the work in Tagger SB, the 480VAC outlet is needed. Coordinated with F&O and Hall D -- outlet was in-use to power a temporary VFD for a pump for the Hall D Chiller system. There are two pumps, and given the current maintenance status of Hall D they confirmed no issue operating on one pump until flushing wraps up tomorrow.

The 480VAC outlet is ready for MSSG as of now.

Wired RF cables to the cross connect and made new, longer hoses for circulator LCW return. In the process of installing new LCW manifold fittings, some hard sediment buildup was noted on the removed fittings. Since things have been going at a good pace, we're taking the time to have the fittings that are staying in the machine cleaned to remove some of the gunk. We're aiming to have the water back on and leak checked by next week.
