Generally smooth shift.

Run 11936 ROC hung so run ended early

Run 11939 reduced BLAST toroidal field 20% to see if the positrons (90% of our event rate) could be tricked into missing the second level trigger. They weren't ! Just managed to find some lower energy ones to bend into the acceptance. Oh well. Back to the drawing board.

Run 11940 Junk

Run 11941 Everything back to normal, Cycled holding fields just to be on the safe side.

Good runs 11936-11938, 11941-11942
