Collisional Relaxation in Multi-Ion Species Plasma

POSTER

Abstract

When an external forces, such as gravity or centrifugal forces, are applied to a magnetized multi-ion species plasma, the relaxation of ion density profiles has several distinct timescales. Here we identify and explore intermediate timescales and describe metastable states of the plasma. In particular, we are interested in differential ion transport[1].
We discuss implications of metastable ion density profiles in the context of different devices, such as a Wave-Driven Rotating Torus[2] (WDRT) or a plasma centrifuge.
