Abstract

In an electron beam tube such as a gyrotron, electron dissipation on the collector wall is often quite non-uniform due to radial concentrations of the electrons. The dissipation is made more uniform by pseudo-random scrambling of trajectories by transverse magnetic fields which are non-uniform in transverse and axial dimensions.
