Briefly: 

--> 5 pass beam was restored yesterday during the swing shift 

--> after IOCHLA issues and raster issues (that required Bill Gunning coming in to change a power supply) we got 5 uA rastered beam to check the beam centering on the target and the raster size

--> we switched to production on LH2 at 15 uA with 2 by 2 raster by 10:15 pm

--> we had a smooth production running over night until the beam studies downtime this morning

--> right now the hall is in controlled access 

--> once the beam is restored after the beam studies the plan is to do a Moller measurement; when that's done we resume production
