Simulation of Alpha Particles in Rotating Plasma Interacting with a Stationary Ripple
Authors: Abraham J. Fetterman and Nathaniel J. Fisch
Abstract:
Superthermal ExB rotation can provide magnetohydrodynamic (MHD) stability and enhanced confinement to axisymmetric mirrors. However, the rotation speed has been limited by phenomena at end electrodes. A new
prediction is that rotation might instead be produced using a magnetic ripple and alpha particle kinetic energy, in an extension of the alpha channeling concept. The interaction of
alpha particles with the ripple results in visually interesting and practically useful orbits.
