Magnetized double‐plasma device for wave studies
Th. Pierre,G. Leclert,F. Braun +2 more
TL;DR: In this article, the characteristics of the magnetized plasma obtained in a modified double-plasma device are presented and the afterglow measurements reveal a very efficient confinement of the ionizing electrons, with a decay time of 0.2 ms.

Spatiotemporal structure of low frequency waves in a magnetized plasma device
M. Matsukuma,Th. Pierre,A. Escarguel,D. Guyomarc'h,G. Leclert,F. Brochard,E. Gravier,Y. Kawai +7 more
TL;DR: In this article, the spatiotemporal structure of nonlinear low frequency waves in a magnetized plasma is studied, and it is shown that the m = 2 azimuthalmode exhibits clearly a rotating spiral structure when the diameter of the plasma column is smaller than the inner diameter of a tube.

Formation of spiral structures and radial convection in the edge region of a magnetized rotating plasma
TL;DR: In this paper, the rotation of a cylindrical plasma column in a magnetic field has been studied in the linear section of the new plasma device Mistral, and the detection and the study of the spatio-temporal evolution of structures in the turbulent regime have been performed by means of a new enhanced conditional sampling technique.

Direct observation of a cross-field current-carrying plasma rotating around an unstable magnetized plasma column
S. Jaeger,Th. Pierre,C. Rebont +2 more
TL;DR: In this article, the existence of a rotating peripheral plasma is correlated with a radial cross-field electron current, where the ionizing electrons injected along the axis of the plasma column contribute to the accumulation of negative charges when the axial collector is at floating potential.

Ion velocity distribution function investigated inside an unstable magnetized plasma exhibiting a rotating nonlinear structure.
TL;DR: For the first time the spatiotemporal evolution of the IVDF is studied using time-resolved laser induced fluorescence to explore the ion's interaction with the nonlinear wave propagating inside the column and at the origin of plasma transport outside the limiter.
