Entry number 373523

We had a very productive day, taking beam on an nicely polarized target 
throughout day and swing shifts.  We had a couple hours lost in the day 
shift due to ion chamber trips near the beam dump and an MCC IOC reboot.  
Other than this, the beam has been very steady.

We will continue taking production data on ammonia throughout the night.  
The target will be changed from Top negative to Bottom positive once the 
Top cup polarization dips below -25% consistently.  An anneal will likely 
be necessary during day shift tomorrow.

Continue following the run plan.  Once this point is finished, follow the 
run plan dated April 9th, which has a host of points to be completed at 
this energy setting.
