4L Ring

After a lot of steering work, it was found that to put the MXS3S02 BCom back on design and to limit scraping, a ring in 4L was fairly unavoidable. Leaving it in for now. I did a zero pause so we can see a little bit better when it deviates from that ring.

NL13-7 Loss of Communication

18 hours 52 minutes ago
Log Number: 4477969Logbook(s): Entry Makers: kernsBody: 

Rebooted 1L13-7 several times to restore comm's that dropped zone out of filaments last night at 2310. Cavity 5 and 7 also had latched arc detector faults in idle state. After comm's restored in cav.7, tried putting the zone back into Idle but it dropped back to null with no Acknowledge annunciated. Since this zone is GSET 0 for low energy, I will have to schedule it for next maintenance day to reboot IOCNL2 reboot (NL11 is in RF on this IOCNL2 !!)

Follow-up Re: IHA4E01 Y-plane Emittance Measurement Analysis

Log Number: 4477959Logbook(s): Body: 

We are not using that to match the machine since it looks like we are badly mismatched coming into ARC4. We have other indications on the 4S01 viewer and bpms that this is the case.
The next course of action is to optimize S/R steering, clean up orbits and then do a recombiner adjustment at 3R (or possibly use 3S02) to reduce the beam overfocusing in Y at 4E01.
After this, we will redo the match.
