The Effect of Externally Applied 3D Fields on NSTX Edge Turbulence

Autor: Hanson, Michael O., Orlov, Dmitri M., Zweben, Stewart, Wingen, Andreas

We report on a study of the structure of edge turbulence in NSTX H-mode discharges with applied n=1 and n=3 non-axisymmetric magnetic perturbations. The edge turbulence is diagnosed in NSTX using the gas puff imaging (GPI) system to understand how th

Harnessing mass differential confinement effects in magnetized rotating plasmas to address new separation needs

Autor: Gueroult, Renaud, Rax, Jean-Marcel, Zweben, Stewart J., Fisch, Nathaniel J.

The ability to separate large volumes of mixed species based on atomic mass appears desirable for a variety of emerging applications with high societal impact. One possibility to meet this objective consists in leveraging mass differential effects in
