0L06 energy measurement

5 hours 41 minutes ago
Log Number: 4468325Logbook(s): Entry Makers: jhowardBody: 

Centered beam through the x-position as required. Tried sending to 4D, but couldn't find beam on the viewer. Did some vertical steering too. Turns out I just didn't lower the weaken the magnet enough to see it on the viewer.

Like swing had found, we are about 10 MeV short of MMS energy. I did phase on the spectrometer and found a bit of energy, but I was at a ever so slightly lower energy than what swing found. Probably user error.

Restoring to the previous all save, then we will let the Vertical Wien soak for the rest of the shift.

Laser Hut Temperature alarm

7 hours 3 minutes ago
Log Number: 4468323Logbook(s): Entry Makers: jhowardBody: 

We have started to get constant alarms regarding the laser hut temperature. Every so ofter, the temp will read a spike that pushes it just over the alarm limit. The average temp is showing as slightly elevated, just in minor alarm at 29 degrees. The ~1 degree spikes don't seem real.

This was found last year too, and the discussion points to the same we found here.

For now we will bump up the alarm limit so the spikes don't trip over it as often, but can be reset to 30 if needed.

Beam to ILD

7 hours 54 minutes ago
Log Number: 4468321Logbook(s): Entry Makers: jhowardBody: 

Picked up from swing shifts hard work. Beam was stuck at the start of the chicane, with too low energy to make it through. I spent some time trying to find some more energy, but RF had been phased and there wasn't more to be gained that way. I then tried steering the 0L region some more, but that did not get me any further into the 0R region either.

since I could not find anymore energy, I started to adjust the 0R01 dipole to make it through at the lower energy, weakening all of the chicane dipoles while trying to keep things balanced as best as I could.

1L19 All cavities tripping on arc test faults

8 hours 2 minutes ago
Log Number: 4468320Logbook(s): Entry Makers: jhowardBody: 

Over the course of several hours, 1L19 will slowly trip off all cavitieso n failed arc tests. It seems to start with cavity 2, but all of the cavities will trip off. We will leave them off as they trip for now.

0L03-8 Quenching at 7.7

8 hours 8 minutes ago
Log Number: 4468319Logbook(s): Entry Makers: jhowardBody: 

Cavity started to quench, and CWWT had a spike. We brought it down to 7.5 for now. It may recover the 0.2 MV/m, but for now we had adding some to 0L04-7/8 to make up the energy.

We will continue to keep an eye on it.

Injector Set Up: FC2 - 0Rish

11 hours 34 minutes ago
Log Number: 4468317Logbook(s): Entry Makers: bschaumlBody: 

Piggybacking off of Jerone's setup from 1/31, we started working on getting A beam from FC2 to the ILD. Collinearity did not restore well, partly because phases downloaded from the allsave for the warm RF didn't take until one wiggled the slider, but even afterwards we struggled to get all four beams on top of one another. We decided to punt on optimizing collinearity and forge on with beam only from the reference laser.

Unfortunately, with a couple cavities missing in the pre-accelerator cryomodules, LEMi would only manage about 116 MeV.
