Arc A Vacuum Burp

Looks real. We aren't sending beam here though.

Seems to happen occasionally (see figure 2 and attached elog). It's not an issue now but may be when we are setting up beam to Hall D. VIPAA05 Looks to be the most affected.

Apologies if there is already an Ops-PR about this. I couldn't find one.

As always, ensure the PTW is on-issue before proceeding. RAM Movement request will need to be coordinated with RadCon for removing the in-place PTW.

4E steering to reduce ILM2T09 and IIX2C00

Started getting ILM2T09 trips as we ramped Hall C up to 17uA from 8uA.
Noticed we were running Extraction at -15mm. Slightly nudged 4S10H corrector +200 G-cm over 15 mins while monitoring locks to reduce ILM2T09 signal as well as IIX2C00, bringing IPM4E02 to -14mm.
Hall B Halo seems to have less noise as well.
