New raster power supply checkout completed by  21:00 yesterday.  An in-depth report is being compiled from my RC perspective.  Raster PSU replacement guidance/instructions are being written up by Bill G.   

There is an outstanding 1mm shift in beam position.  The root cause is still unknown, but it is less likely to do with the raster work and more likely to be due to changes in the beam on target since 1/12/23.   A plan has been put in place to correct the target offset.

Smooth running with a 1mm target position shift over night.  We completed setting 5 and are now moving to setting 6.  We will likely finish settings 6-10 in the next 24 hours.

We will have an RC meeting today to discuss the next run settings.
