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…

Structure of a collisionless pair jet in a magnetized electron-proton plasma: Flow-aligned magnetic field
Mark Eric Dieckmann, Martin Falk, Peter Steneteg +6
We present the results from a particle-in-cell (PIC) simulation that models the interaction between a spatially localized electron-positron cloud and an electron-ion plasma. The la…

Structure of a collisionless pair jet in a magnetized electron-proton plasma: flow-aligned magnetic field
M E Dieckmann, D Folini, I Hotz +4
We study the effect a guiding magnetic field has on the formation and structure of a pair jet that propagates through a collisionless electron-proton plasma at rest. We model with…
