Particle simulations of relativistic electron beam injection from spacecraft

Particle simulations of relativistic electron beam injection from spacecraft

[ 1 ] Linear accelerators producing relativistic (5 MeV) electron beams are now down to a size that allows them to be flown on spacecraft and sounding rockets. This opens up new opportunities for atmospheric/ionospheric modification experiments where the mesosphere and lower thermosphere regions can be perturbed down to 40-km altitude. In this paper the relativistic electron beam injection proc...

Relativistic particle acceleration in an electron-positron plasma with a relativistic electron beam

Results from three-dimensional electromagnetic particle simulations of an electron-positron plasma with a relativistic electron beam (y=2) are presented. As part of the initial conditions, a poloidal magnetic field is specified, consistent with the current carried by the beam electrons. The beam undergoes pinching oscillations due to the pressure imbalance. A transverse two-stream instability i...
