Coupled Dipole Oscillations in an Intense Relativistic Electron Beam

Horizontal phase-space distortions arising from magnetic pulse compression of an intense, relativistic electron beam.

We report detailed measurements of the transverse phase space distortions induced by magnetic chicane compression of a high brightness, relativistic electron beam to subpicosecond length. A strong bifurcation in the phase space is observed when the beam is strongly compressed. This effect is analyzed using several computational models and is correlated to the folding of longitudinal phase space...

Diocotron instability of an intense relativistic electron beam in an accelerator.

High current annular electron beam in an accelerator is subject to various instabilities. A general fluid-Maxwell theory of the diocotron instability is developed for an infinitely long and azimuthally symmetric annular electron beam propagating along an external magnetic field. In contrast with the treatment used in the conventional diocotron instability, the assumptions of tenuous electron be...

Stimulated Raman Scattering by an Intense Relativistic Electron Beam Subjected to a Rippled Electric Field

Generation of submillimeter radiation by stimulated Raman scattering in an intense relativistic electron beam subjected to a spatially periodic transverse electric field is examined. The requisite electric field modulation can be obtained by rippling the wall of the conducting drift tube. When the electron beam is subjected to a periodic longitudinal electric field, short wavelength plasmons, r...
