Looks like pass 3 separator recovered. Will check orbits when we recover from the MBC4R06H mismatch.

After Hall B, Hall C, & Hall D all reached current setpoints...
Hall B's Attenuator was at ~490
A3 interception was at ~0.075

But Hall B's attenuator continues to climb by +205 with no change in Hall B's current at 2C24

INJ interception is just soaking it up like a sponge until it trips

Day shift was having considerable difficulty with beam loss in the 5E region and elevated halo rates in Hall B at passdown.

After a bit of poking around and investigating setpoint changes around the machine using ReCap, I loaded the all-save from the beginning of Owl shift last night.

Corrected pathlength, linac gang phases crested, and allowed the orbit locks to converge to the hall dumplettes (C beam for passes 1 through 3, D beam for the higher passes).

Brought halls up to requested current one-at-a-time starting with C, then B, and finally D.

All three halls are now receiving their req
