[Halla_running] [New Logentry] Follow-up Re: RC update, 13 October

The magnetic field measurements are underway now, we will do both the gradient probe and compass measurements.  When they finish, the alignment of the lasers without the cell will be done, followed by the installation and alignment of the target ladder and the cell.

We plan for Jesse to start the hall checklist to get back to Controlled Access at about the start of day shift, and anticipate that we'd have the sweep of the hall around noon.  OPS will be making the Wien angle change and starting to get 2-pass beam set up to our dumplette while that is going on.

Plan once we get locked up tomorrow:
1)  Beam restoration at 2-pass and check of the spot size at the target
2)  Target centering and raster size check on the carbon hole target at ~5uA (~1hr)
3)  Test of the ramp rate protection system with target out
4)  Moller polarimeter run (~8 hr)
5)  Target centering recheck on the carbon hole to ensure everything came back properly after Moller
6)  Short reference cell run with cell evacuated
7)  Ion chamber calibration of reference cell at varying pressures, if desired by OPS.
8)  Begin running on the He-3 cell
