Transport of intense charged-particle beams in a coaxial magnetic undulator

The system of dynamics equations describing the propagation of high-current charged-particle beam in a coaxial drift-tube in combined longitudinal homogeneous (guide) and periodic magnetostatic undulator fields is formulated. The self-electric field and both longitudinal and azimuthal components of self-magnetic field of charged-particle beam averaged over the undulator period are obtained.
