    Comments: beam tuning at start of shift. ~19:30 MCC delivers 110uA stable beam ~22:00 Ask for beam to be centered for cryotarget test. MCC cannot move it sufficiently in x (reach -1.5mm, want -3.0). ~21:30 JP comes in for test of high current on cryotarget. MCC can only deliver 85 reliably. ~22:00 Some cryo flow problem; all right arm magnets and left arm Q1, Dipole trip. After He level restored, all left arm magnets reset, and right arm Q1. Right arm dipole and Q3 are off (Q3 will have to be reset from hall, not sure about dipole but not important with Q2 and Q3 down). Starting lumi boiling studies at end of shift, but still limited to 85 uA
