The orbit lock PVs for Arc 6 and above are not changing. It seems like just the ArcXOrb:Onoff PV, but I have not done an extensive investigation. The Hall orbits locks are also not updating. We have been turning them on, and the locks themselves are running correctly, only the PVs seem to be having an issue.

iocse15 appears to be unresolved in the alarm handler, but all signals on this ioc are reporting just fine. Maybe the alarm handler needs a reboot?

Last night we found current stability is better with a wider slit, and it's easier on the gun. No detriment to halo rates at this setting.
