    keyword=110uA high current run finish, 2uA run starts

    We finished the 110uA high current run. I ask MCC for 2uA beam, and turn on the VDC the same time.

    Note: The last run used as deadtime analysis is #25727, #5274, which is also 110uA high current run, but the tagger is on at these two runs. Our real high current run with no tagger starts from #25728, #5275 at 23:48 yesterday and finished at #25729,#5276 at 01:34 today, which lasted for 1hour 46minutes in total. We decide to switch to low current run which is more important to us, just in case MCC has some problem and cannot provide enough low current beam time before we ramp down the right arm dipole at 4:00am.

    The prescale was changed to RHRS as 2,and LHRS as 3. The first run is #25731,#5278.
