Abstract :
A three-dimensional model of intense bunched beams is developed for cylindrical and corrugated conducting pipes. Updated comparisons between the current limits derived from this model and experimental data from PPM focusing klystrons are presented. An electrostatic Green´s function is formulated for azimuthally symmetric slow-wave structures. Analytical and numerical results are presented for the potential of a periodic bunched pencil beam in a small-rippled waveguide approximation.
