Stability properties of an intense relativistic non-neutral electron ring in a modified betatron accelerator

Kinetic Stability Properties of an Intense Relativistic Electron Ring in a High-current Betatron Accelerator

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...

Betatron Radiation of an Off-axis Injected Electron in a Laser Wakefield Accelerator

The electrons injected into a laser wakefield undergo betatron oscillation and give rise to the emission of intense X-ray radiation. To investigate the generation conditions of the X-rays, the relativistic motion of an electron injected in an off-axis position has been simulated with wakefield profiles which are pre-calculated with a two-dimensional particle-in-cell code. The wakefield with a p...
