Entry Makers: eformanBody:

Beam steered to the 2S region without too much difficulty aside from RF trippiness (MO problems?). Zone gang phase followed by cavity phasing of the linac.

Hand phasing of SL finished. Final BDL of ARC2 is ~2.6% lower than expected (by "expected" I mean the the 1060 MeV BDL setpoint scaled down to 850 MeV).

Next up - Phaser.

After returning from the LERF ODH alarm investication we found that beam dove in the vertical plane starting at 0R06 or so and had to be resteered. I don't believe any locks caused this.

It seems most zones are weathering whatever is making the phase freak out, but 2L24 seems more susceptible to it, with a handful of it's cavities tripping on PLDE faults when all the other PLDER alarms show up throughout 2L.
