Collinearity is pretty good! Viewer walk with A, B, & C. Now that I have a feel for it, I'll run through the procedure and mark things up tomorrow night.

2L25 is quiet but there have been two pressure bursts and the foreline pressure is up from yesterday evening, figures 1 and 2. SL 2K overview Figure 3.

SL helium total ~20000 liters versus 27000 nominal.

I don't understand why the RT readings on 2L23-25 are so low. 2L04 inlet and outlet temperature diodes were likely fried by radiation - the module has lots of field emission. 2L16 is also a C50.

Nowhere to go with RF HCO tonight, so I'll be practicing the chopper setup procedure with the V Wien soaking at 90.

We were unable to fill 2L03 completely, thus leaving the tanks slightly more filled than expected. With tanks 1, 3, and 5 online at around 10.3atm, we should be able to dump 2 tubes in the morning (raising tank pressure to around 13atm) without needing immediate liquefaction into the linac or dewar.

After the pumpdown while we were attempting to control cryomodule level and tunnel pressure, we discovered that 2L02 and 2L16 did not have remote electric heat control. We could not fix these issues tonight, but hope to be able to address them tomorrow (Saturday) as 2L16 is a cryomodule which has been given the go ahead for RF testing.

There have been RF heater problems all night. 2L16 is still an issue and maybe 2L06. Attempted contact with RF Primary and Secondary on-call with no success. Tried to contact d. Gehlaar and O. Garza with no success either.
At this point Cryo is going home for the night. They filled 2L04, 2L22, 2L23 and 2L24 and said I could turn on RF in those zones. Those zones are listed as do not turn on RF zones. Cryo will be in tomorrow to continue filling. I provided them with the list of zones we are allowed to turn on RF in for priority tomorrow.

So far everything looks fine with the LL at 88% and low turbo foreline pressure. If the leak opens up the turbo will trip. If that happens, lower LL to ~70% until Tuesday.

Figure 1: turbo screen.

Figure 2: CC and pressure at the tee. Only the last is on a second vertical scale.

Figure 3: LL and JT are on the displayed vertical scale. Foreline pressure is on 15-20 mTorr scale. Turbo power autoscaling so look at range.
