Mode transitions and spoke structures in ExB Penning discharge
M. Tyushev, M. Papahn Zadeh, N. S. Chopra +7
Two-dimensional particle-in-cell simulations in the (radial-azimuthal) plane perpendicular to the axial direction of a cylindrical ExB Penning discharge are presented. The low-pres…
Ray tracing methods for wave propagation in moving anisotropic media : application to magnetized plasmas
Aymeric Braud, Julien Langlois, Renaud Gueroult
The propagation of a wave in a medium is generally affected when the medium is moving with respect to the observer. Because plasma equilibria often involve plasma flows, for instan…
Fresnel drag in a moving magnetized plasma
Julien Langlois, Aymeric Braud, Renaud Gueroult
The change in direction of the wavevector and group velocity experienced by a wave refracted at the interface of an anisotropic medium in uniform linear motion are determined analy…
Signature of inertia on light dragging in rotating plasmas
Julien Langlois, Renaud Gueroult
The signature of light dragging in a rotating unmagnetized plasma is studied analytically. In contrast with previous work which focused exclusively on the drag effects arising from…
Plasma potential shaping using end-electrodes in the Large Plasma Device
R. Gueroult, S. K. P. Tripathi, F. Gaboriau +2
We perform experiments in the Large Plasma Device (LAPD) at the University of California, Los Angeles, studying how different end-electrode biasing schemes modify the radial potent…
Rotating Alfvén waves in rotating plasmas
J. -M. Rax, R. Gueroult, N. J. Fisch
Angular momentum coupling between a rotating magnetized plasma and torsional Alfvén waves carrying orbital angular momentum (OAM) is examined. It is not only demonstrated that rota…
