Plasma Theory Seminar
Special Plasma Seminar
Plasma rotation: from mass separation applications to light manipulation
Date: Wednesday, February 24th
Time: 9:00 am
Place: Zoom Meeting
Speaker: Renaud Gueroult, Laplace, Université de Toulouse, CNRS, Toulouse, France
Abstract: Rotation phenomena in plasmas are found everywhere, from plasma technologies to laboratory experiments and all the way to astrophysics, and can lead to peculiar effects. In this talk, I will first discuss how the mass differential confinement properties found in a rotating plasma could enable developing mass separation technologies [1] with high upside potential for societal applications including nuclear waste cleanup and rare earth recycling. I will then show how the problem of crossed-field rotation control is intimately tied to the question of what cross-field conductivity is in a rotating plasma, and how answering this basic question is also crucial to certain alternative magnetic confinement fusion concepts [2]. Finally, as a further illustration of the peculiar effects of rotation, I will briefly touch on the basic effect of rotation on wave polarization, and how this may be of importance for pulsars' physics [3] and light manipulation applications.
