FEL gain as a function of phace displacements induced by undulator intersection gaps
- Kurchatov Institute, Moscow (Russian Federation)
Gain characteristics are analytically considered for FEL based on a multisection undulator with short intersection gaps. It is shown that small phase displacements between laser beam and electron beam respectively caused by the above intersection gaps can seriously change the gain resonance frequency as well as gain curve shape. This effect is different from that of OK and can be used for fast undulator tuning or for its tapering.
