We initially centered through the buncher, then proceeded to fine tune dechopping, while making sure that all beams time of arrival to the booster was equal.
We checked D Laser bucket and verified 750 MHz timing on IPM1I02.
Then we checked booster phasing, and found that the 7 cell was on crest while the 2 cell had been on phase then 35.5 degrees had been subtracted. We left it as we found it at the beginning of shift after scratching our heads for far too long trying to find out which cavity should be off crest.

Setting up the booster
Log Number: 4467950Logbook(s): Entry Makers: jhowardBody:
We needed some minor steering to get to the 2D dump. Checked the phases of the booster, and they were already pretty close to on crest. Adding the 35.5 degree phase offset caused us a few hours of trouble. We found that we were not centered through the booster.
Using dither and the 0L01 viewer, setting dither to adjust R028PSET 10 degrees from where we found the crest, we centered through the booster using the last two 0I correctors.

Centering through MFX0I07 and A3/A4
Log Number: 4467948Logbook(s): Entry Makers: jhowardBody:
Picked up from swing shift roughly steering to FC2. Tried to use the 0I07 viewer, but beam was clipping on something. Checked and found we were hitting A3, so we jumped forward and checked centering on A3 and A4 first to make sure we could see good beam on the viewer.
We used 0I07 viewer to roughly center through A3, as well as looking at interception. Then used 0L01 viewer to center through A4.
