Preferential acceleration of positrons by a filamentation instability between an electron-proton beam and a pair plasma beam
M E Dieckmann, S J Spencer, M Falk +1
Particle-in-cell (PIC) simulations of collisionless jets of electrons and positrons in an ambient electron-proton plasma have revealed an acceleration of positrons at the expense o…

Expansion of a radially symmetric blast shell into a uniformly magnetized plasma
M E Dieckmann, Q Moreno, D Doria +7
The expansion of a thermal pressure-driven radial blast shell into a dilute ambient plasma is examined with two-dimensional PIC simulations. The purpose is to determine if laminar…
