IIX1L02_gDsRt increased at 1420

GMES sum didn't change from period before it was turned off. Higher gamma rate coincided with restoration of gradient. I believe the electrometer was supposed to be swapped today but I deleted the ATLis email so I can't be sure. Dose rate is back down now.

East Arc Box supplies are good to turn on

22 hours 41 minutes ago
Log Number: 4475191Logbook(s): Entry Makers: mockBody: 

Received word from Operability that the LCW manifold was put back in place. The East Arc Box supplies are good for turn on. Arc 1, 3, 5, 9, and RSEP9.

Arc 7 still a no go due to YBBS06.

DC power has pulled out E-Stop on the affected box supplies so we can turn them on remotely.

Latest update is next full-on maintenance day will not be until next week (week of 3/16). I take it you are looking for a time when the BoxPSs will be off. There will be an opportunity with this condition present tomorrow, Tuesday 3/10, between 0730 and ~noon. Would you be ready to do this work tomorrow, or want to wait until next week?

Updated MXM3S03 shunt current limiting coefficient

23 hours 15 minutes ago
Log Number: 4475183Logbook(s): Entry Makers: mockBody: 

Permission from DC power to update current limiting coefficient to 0.116.
We still have to test to see if the design setpoint is now within limits. Can't do that unless Box supplies are on and shunts powered.

Do not turn on East arc Box supplies

23 hours 25 minutes ago
Log Number: 4475178Logbook(s): Entry Makers: mockBody: 

Received a report from Operability that an LCW manifold was removed during YBBS06 work, affecting the East Arc Box supply magnet strings. This includes Arc 1, 3, 5, 7, 9, and RSEP9.

DC power has enabled the E-Stop on the affected box supplies so they are not inadvertently turn on by Ops.

1D dipole (MBO0I06) setpoint for 140 kV operations

1 day ago
Log Number: 4475162Logbook(s): Entry Makers: mockBody: 

Looked back at the 2024 run when we were running a 140 kV Gun to see what the MBO0I06 dipole was set at for 1D running.

Looks to be 298 mA.
The dipole setting now for 200 kV is 372 mA.

The button / control screen Ops uses to set this magnet will need to be updated for that value. Perhaps we should also add in another row on the table for this energy and dipole current.
