Reconfiguration, Commissioning and Calibration 1st phase (Starting on April 15 at 9:30am)

 - Energy change: 4 pass --> 3 pass (2-3 hours)
     1) Change Right HRS polarity to negative
     2) Left & Right HRS at kin 5.2: theta=25deg, Po=2.995GeV/c (RQ3=2.6273GeV/c)
 - Set up for maximum current (95 uA)
 - BCM calibration (1 hour)

1st phase: Helium-4, Deuterium and Carbon running

The 4He and 2H might not be ready for beam simultaneously. Therefore, the plan is to take data on 4He, then move to carbon. During the data taking on carbon, lower the cryo-load on 4He and prepare 2H for beam (it should take 5 min). Take data on 2H. Then on optics. Then switch kinematics and do the same thing in reverse order: Optics --> 2H --> Carbon --> 4He.
