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%.
