Summary of Beam Properties in JLab Injector
| Beam Kinetic Energy, T (MeV) | 3.0 – 8.5 |
| Beam Current (µA) | 0.01 – 100 |
| Absolute Beam Energy | 0.67% |
| Relative Beam Energy | 0.05% |
| Energy Resolution (Spread), σT /T | 0.06% |
| Beam Size, σx,y (mm) | 1 – 2 |
The goal is to reduce the uncertainty on the absolute beam energy to 0.1% and achieve a relative beam energy of 0.05%.
