Filamentation Instability of a Relativistic Hollow Electron Beam available in PDF, EPUB and Kindle. The filamentation instability properties of a relativistic hollow electron beam confined in axial flow by a uniform magnetic field in a pipe are investigated via the Vlasov-Maxwell equations. The instability is found to have two side-bands, one with a spectrum of positive wavenumbers k and the other with a spectrum of negative wavenumbers. The spectral point k=0, associated with the diokotron instability, is excluded from the filamentation instability's two unstable sidebands. Only in the limit of zero axial beam flow, the diokotron instability becomes asymptotically part of the filamentation instability spectrum. In this limit the filamentation instability's two sidebands merge asymptotically and symmetrically toward the diokotron instability spectral point, k=0, in agreement with the basic driving physical mechanisms and geometry configurations for these two distinct and different instabilities.

The authors report nonlinear studies of the Weibel instability of a relativistic electron beam in a plasma. If (n sub b) “(n sub p), the beam splits into self-pinched filaments at density (n sub p). These filaments then recombine into a single dense beam, from which the return current is expelled. A fraction about nu/gamma of the beam energy is lost to magnetic energy, and significant plasma heating occurs. (Author).

Diocotron Instability of a Relativistic Coaxial Multi-Ring Hollow Electron Beam available in PDF, EPUB and Kindle. The diocotron stability properties of a relativistic coaxial multi-ring hollow electron beam are investigated using a macroscopic cold fluid description based on moment-Maxwell equations. It is found that for a broad range of beam parameters and somewhat more general type beam profile the growth rate of instability has a sensitive dependence on fractional charge neutralization, relative position of the rings with conducting wall and gap-length of the rings. In the case of a sharp boundary density profile, the beam can be stabilized easily by a small fractional charge neutralization with appropriate gap-length. The growth rate can be either enhanced or reduced depending on the position and gap-length of the rings. (Author).
