    The first CW beam after the linac energy change came at about 8pm. They were only able to deliver ~150uA to Halls A+C, and needed to move the spot on the source (although we are now limited to ~140 uA).

    After the spot move, and adjusting the beam size, raster size, and beam position, we started data taking (initially 80uA, later 85) at 11pm.

    Beam enrgy was raised slighly before run 4528 (see halog#208262), and later we were informed it would be reduced back to the old value (halog#208289), but at the moment, we are still at the 'higher' value of 875.6 MeV.

    Ended with about 1 hour of good data on 3He, average current of 80-85 uA.
