As discussed in gradient team meeting.  No entry to linacs.

0730 stop beam to halls, putting in dumplettes.
0730-0800 allsave with zero position, D tune beam.  Fopt D beam.  Harp 
swipes at 1E01, 2E01, 4E01, 6E01, 8E01, AE01.  Put in inline dump.

in parallel

0800-1200 change Wien angle to 76.9 degrees and general injector 
checkout to inline dump.  Use MMS/eDT to set Hall A to pass 5. Cycle A 
magnets.

0800-1200 RF group works to recover SL cavities and reduce 2L22 trips

------------------------

My thoughts for rest of day shift:

1200-1300 lem, phase recovered RF.  Try NL lem fudge 0.984, letting 
energy lock bring beam back to center to get more 1L19 headroom.  Or run 
the fudgeit test starting with lem fudge 0.981 as now.

1300-1500 with C and B beams, resteer AT line to get MBDAT04V close to 
zero with B/C beams in the correct locations at Lambertson.  Adjust 
vertical RF separator phase for three-way split if needed.  Get A beam 
fifth pass to 1C05 dumplette.

1500 Assess whether to take A beam to Hall A dump and adjust transverse 
optiocs empirically or whether significant optics work is required in 
main machine.

1500 (Nick) rewrite swing shift PD plan ;-)
