Summary of Beam Properties in JLab Injector
| Beam Kinetic Energy, T (MeV) | 3.0 – 7.75 |
| Beam Current (µA) | 0.01 – 100 |
| Absolute Beam Energy | 0.36% |
| Relative Beam Energy | 0.1% |
| Energy Resolution (Spread), σT /T | 0.06% |
| Beam Size, σx,y (mm) | 1 – 2 |
Goals: - Increase beam kinetic energy to 8.5 MeV. - Reduce the uncertainty on the absolute beam energy to <0.1% and achieve a relative beam energy of <0.02%.
