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) |
- 4th Pass (E = 8.8 GeV) Time estimate: 22 days
| Target | Raster | Ebeam [GeV] | P0 [GeV/c] | θe [deg] | Q2 [GeV2] | Electron Rate [Hz] at 20 μA | days at 20 μA |

- 5th Pass (E = 11.0 GeV) Time estimate: days
| Target | Raster | Ebeam [GeV] | P0 [GeV/c] | θe [deg] | Q2 [GeV2] | Electron Rate [Hz] at 20 μA | days at 20 μA |
