Strategies for minimizing emittance growths in high intensity CW FEL injectors
- CEBAF, Newport News, VA (United States)
We discuss beam emittance growths in high intensity CW FEL injectors due to linear and non-linear space charge fields, phase space bifurcation, skew-quad effect, longitudinal momentum modification by space charges in bends, and equipartitioning, etc. We generalize Kim`s RF laser gun theory to DC laser guns. We discuss the traditional free energy theory of emittance growth. The best strategies for designing high-intensity CW FEL injectors are derived, and their application to the design analysis of the CEBAF 10 MeV DC laser gun CW FEL injector test stand is discussed.
