Proton Elastic Kinematics

During each pass change, we require a spectrometer pointing survey for the Left HRS and sometimes for the Right HRS.

* If you need to increase the spectrometer momentum setting, make sure you cycle Q2 and Q3 as per the cycling procedure. 
* Elastic electron rates assume 60 μA on 15 cm LH2 target, 5 mSr acceptance.
* Use the following prescale factors: ps1=1, ps2=1, ps3=1, ps8=100 for the Right HRS. ps1=1, ps2=1, ps3=1, ps7=1, ps8=10000 for the Left HRS. All other triggers should have zero prescale factor.
* For the carbon pointing run, decrease the spectrometer momentum for the left and right spectrometers to 1.0 GeV/c. The right dipole will need about 2-3 hours to settle.
* Take a one hour run on the optics target.
* After the carbon run is completed, then increase the spectrometer momentum back to the elastic setting. Again, the right dipole will need about 2-3 hours to settle Make sure to cycle the right Q2 and Q3 when increasing the momentum.
* The 15 cm dummy runs need to be taken at the elastic setting. So keep the momentum as is for this run.
* We should take dummy target data to accumulate at least 10% of the LH2 statistics.
* A GMp expert will check the data quality.
