Abstract :
A one-dimensional multiparticle free electron laser (FEL) amplifier simulation code based on a single particle interaction model is used to determine laser gain and energy spread in an FEL amplifier in which gain is enhanced by means of an axial electric field. Limitations on achievable laser intensity due to limits on the energy spread an energy recovery system can accept are discussed and a comparison is made with tapered wiggler systems.
