Cycled EQ2 and EQ3 to 1600A.

He3 elastic runs are at 5uA with feedbacks on (energy feedback is on Hall C).

Very good beam quality during elastic runs, not a single beam trip; changed prescale
factors after run 3033 to increase rate. We should have total of appr. 0.36M elastic
events.
7:03 Finished kin 91 runs; asked for restricted access to change to LH2
configuration; moved target to empty position.
7:34 Start cosmics run# 3036.
