Paper Abstract

Relativistic electron motion is considered in the axi-symmetric system, and a formalism which can be solved semi-analytically in any magnetic field profile is developed. As a special case, the analyses are applied to nonadiabatic magnetic compression of axis-rotating electron beams. The results, which have a direct application to the cusptron or the peniotron microwave tubes, are compared with the predictions obtained by assuming an adiabatic behavior of electron. Beam parameters such as off-centering, Larmor radius, and velocity are examined for optimum beam-wave interaction.
