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

9 hours 22 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

9 hours 32 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

10 hours 50 minutes 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.

Reconfigured gun HVPS interlocks for beam ops

10 hours 51 minutes ago
Log Number: 4475161Logbook(s): Entry Makers: gramesBody: 

Following our weekend gun high voltage repair and testing, today we removed the J6 jumper which permitted the HVPS to enable with the gun vacuum valve closed. I removed the corresponding ABIL entry as well.

We are again in a normal gun HVPS interlock configuration. For example, with the gun valve closed we no longer hve a Global Vac/Valve permissive.
