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.
Target Raster Ebeam [GeV] P0 [GeV/c] θe [deg] Q2 [GeV2] Electron Rate [Hz] at 20 μA hours at 20 μA
15 cm LH2 2 x 2 mm2 4.481 1.706 48.74 5.21 2.4 12 (for 100k events)
15 cm Dummy 2 x 2 mm2 4.481 1.706 48.74 5.21 0.4 2.5 (for 3.6k events)
