Electromagnetic instability supported by a rippled, magnetically focused relativistic electron beam
Published online by Cambridge University Press: 13 March 2009
Abstract
The coupling of volume, long-wavelength TM electromagnetic and longitudinal space charge (electrostatic) waves by the rippling of magnetically focused electron beams is examined analytically. The dispersion relation is obtained and then solved for these types of wave. Instability, with growth rates proportional to the relative ripple amplitude of the beam, is found and discussed.
