Abstract

Analysis of high frequency eigen modes of a cylindrical metallic waveguide filled with a helical wiggler and a relativistic electron beam and guiding by an ion-channel is presented. A relativistic nonlinear wave equation is derived in a form including the coupling of EH , HE , HE betatron (HE - Be), and EH betatron (EH - Be) modes due to ion channel guiding and wiggler magnetic field. Six families of eigen modes are found. The cutoff frequencies in TM , TE modes are illustrated for this configuration. [ABSTRACT FROM AUTHOR]
