Momentum | 0.5 | 1 | 1.5 | 2.5 | (GeV) |
Horizontal | 10.03 | 7.17 | 4.82 | 3.17 | (mrad) |
Vertical | 7.19 | 4.45 | 3.38 | 2.33 | (mrad) |
The beam momentum dispersion has been derived from the Tagger Calibration.
Description of the analysis
...
- beam spot : Truncated Gaussian function parameters (Min, Max, Mean, RMS)
+ Horizontal/Vertical position (mm) : Min (blue triangle), Mean (Black circle), Max (red triangle)
+ Horizontal/Vertical dispersion (mm): RMS (Black circle) - beam divergence : Horizontal/Vertical angles in mrad, clearly depend upon beam momentum.
