Emittance of Transport of Electron Beam in a Free Electron Laser
Abstract
In this work we examine the consequences of finite beam emittance and discuss some of the requirements on the beam transport system in a free electron laser; we will not discuss the operation of the FEL. We concentrate on beams from linear accelerators, but the transport theory is quite general and may be applied to beams from (or in) a storage ring. We discuss a fundamental limitation placed on the beam current density by the finite emittance and the resulting spread in axial velocity, continuous solenoidal focusing, and the possibility of focusing the electron beam with the magnetic field of the wiggler.
