Nonresonant Diffusion in Alpha Channeling
Ian E. Ochs, Nathaniel J. Fisch
The gradient of fusion-born alpha particles that arises in a fusion reactor can be exploited to amplify waves, which cool the alpha particles while diffusively extracting them from…
Trace Impurity Transport in Multi-Species Plasmas with Large Particle Fluxes
E. Litvinova Mitra, E. J. Kolmes, I. E. Ochs +3
A burning fusion plasma has a large inwards flux of fuel and outwards flux of ash. Existing impurity transport theories do not account for a steady-state environment of such large…
Magnetogenesis by Wave-Driven Momentum Exchange
Ian E. Ochs, Nathaniel J. Fisch
When multiple species interact with an electrostatic ion acoustic wave, they can exchange momentum, despite the lack of momentum in the field itself. The resulting force on the ele…
Heat Pump via Charge Incompressibility in a Collisional Magnetized Multi-Ion Plasma
M. E. Mlodik, E. J. Kolmes, I. E. Ochs +1
Stratification due to ion-ion friction in a magnetized multiple-ion species plasma is shown to be accompanied by a heat pump effect, identified for the first time here, transferrin…
Momentum-Exchange Current Drive by Electrostatic Waves in an Unmagnetized Collisionless Plasma
Ian E. Ochs, Nathaniel J. Fisch
For an electrostatic wave interacting with a single species in a collisionless plasma, momentum conservation implies current conservation. However, when multiple species interact w…
MITNS: Multiple-Ion Transport Numerical Solver for Magnetized Plasmas
E. J. Kolmes, I. E. Ochs, N. J. Fisch
MITNS (Multiple-Ion Transport Numerical Solver) is a new numerical tool designed to perform 1D simulations of classical cross-field transport in magnetized plasmas. Its detailed tr…
