Absolute Beam Energy

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%.
