1L06 is online and cold. 1L07 was punted last week due to excessive pressure buildup when attempting to install the return U-Tube.
This morning, a purge rig was installed on 1L07, and we have been flowing through the module since.

I activated the NEG pumps in the 1I beamline. This was last done when they were installed in 2021, so it was time for a reactivation anyway, and they saw a tiny leak due to the gun bakeout and a leak in the gun valve bonnet seal.

Since the pumps are distributed along ~10' of beamline, and I had a pump cart installed only in the upstream location, I activated them in a staggered start/staggered end, starting with the end farthest from the gun.

For reactivation, the NEG should be taken to about 75% of the temperature for full activation.
