Particle, Charge, and Energy Rearrangement in Rotating Magnetized Plasma

ORAL

Abstract

Rotating plasmas are useful for a number of applications, including nuclear fusion and plasma mass filters. Moreover, rotating plasmas -- especially rotating plasmas with several ion species -- often behave quite differently from plasmas that do not rotate. In this thesis talk, we discuss a number of different ways in which rotation can be used to facilitate the rearrangement of particles, charge, and energy. These include cross-field impurity and ash transport; cross-field conductivity; ways of controlling the dissipation pathways to drive temperature differences between species; and fundamental limitations on the efficiency with which energy can be transferred through different classes of reversible and irreversible processes. In uncovering new phenomena, insights into the behavior of neutral fluids can often inform on the behavior of more complicated rotating plasma systems.
