A Scalloped Electron Beam Free-Electron Laser
MetadataShow full item record
Typical high-gain FEL amplifiers employ an electron beam that is â matchedâ to the wiggler so that the envelope remains constant throughout the wiggler. This paper describes a novel approach in which the electron envelope undergoes scalloping motion along the wiggler because the beams are deliberately mismatched at the wiggler entrance. We present an analysis of the electron scalloping motion and the FEL interaction with a scalloped electron beam. Using MEDUSA simulations, we show the advantages of the scalloped-beam FEL and the properties of the radiation beam it produces.
