Title: Effect of beam self-rotation on a Cerenkov free-electron laser

Journal Article · · J. Appl. Phys.; (United States)
DOI:https://doi.org/10.1063/1.342681· OSTI ID:6474048

At large beam currents, the beam space charge produces a radial electric field causing E x B rotation of the beam. As the beam travels through a partially dielectric loaded waveguide, it emits coherent Cerenkov radiation at frequencies ..omega.. = ..beta..v/sub b/+l(..omega../sub ..cap alpha..//..gamma../sub 0/), where l is the azimuthal mode number, ..omega../sub ..cap alpha../ is the angular frequency of rotation, and ..beta.. is the propagation constant.
