Proton Elastic Kinematics
* 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.
- 2nd Pass (Ebeam = 4.5 GeV) Time estimate: 15 hours
| 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 | 1.547 | 52.91 | 5.5 | 1.4 | 7 (for 35k events) |
| 15 cm Dummy | 2 x 2 mm2 | 4.481 | 1.547 | 52.91 | 5.5 | 0.4 | 2.5 (for 3.6k events) |
- 4th Pass (Ebeam = 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 |
| 15 cm LH2 | 2 x 2 mm2 | 8.841 | 2.101 | 48.74 | 12.65 | 0.018 | 21 (for 32k events) |
| 15 cm Dummy | 2 x 2 mm2 | 8.841 | 2.101 | 48.74 | 12.65 | ---- |
- 5th Pass (Ebeam = 11.0 GeV) Time estimate: 39 days
| Target | Raster | Ebeam [GeV] | P0 [GeV/c] | θe [deg] | Q2 [GeV2] | Electron Rate [Hz] at 20 μA | days at 20 μA |
| 15 cm LH2 | 2 x 2 mm2 | 11.021 | 2.204 | 48.74 | 16.54 | 0.003 | 38 (for 10k events) |
