[Halla_running] ~4.8 GeV starting beam energy and left arm at 15 degrees

[Douglas Higinbotham]

Further News:

Accelerator let us know yesterday, that they will likely be starting at 4.8 GeV due to down zones in the linacs; 
though they will be going back up to >6 GeV as soon as they can get so zone up so they can meet their DOE milestone.

Once the milestone is meet, they will like lower the energy again to a point where the trip rate is tolerable.

People should also be aware that the left arm can not go down to its normal 12.5 degrees due to the large exit pipe
that was installed for DVCS.   Ed placed the arm at 15.0 degrees and then placed the pin in the floor so that the 
spectrometer can not be taken to a smaller angle.
