Proton Elastic Kinematics

  • 2nd Pass (E = 4.5 GeV) Time estimate: 15 hours
* 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 20 μA on 15 cm LH2 target, 5 mSr acceptance.
* A GMp expert will check the data quality.
