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%.
