Abstract

We present particle-in-cell (PIC) simulations of minority energetic protons in a deuterium plasma, which undergo a collective instability. We focus on obliquely propagating
modes under conditions appropriate to the outer mid-plane edge in a large tokamak, through
which pass confined centrally born fusion products on banana orbits that have large radial
excursions. A fully self-consistent electromagnetic relativistic PIC code representing all
vector field quantities and particle velocities in three dimensions as functions of a single
spatial dimension is used to model this situation by evolving the initial antiparallel travelling ring-beam distribution of 3MeV protons in a background 10keV Maxwellian deuterium plasma with realistic ion-electron mass ratio. Growth rates of the instability have
been calculated for a range of oblique angles and proton-deuterium concentration ratios,
using electric field and particle data.
