[2608.27853] Counter-rotating density and current structures in a partially magnetized $\mathbf{E}\times\mathbf{B}$ plasma Skip to main content Search Submit Donate Log in Physics > Plasma Physics arXiv:2608.27853 (physics) [Submitted on 28 Aug 2026] Title: Counter-rotating density and current structures in a partially magnetized $\mathbf{E}\times\mathbf{B}$ plasma Authors: Pengze Xiao , Ya Zhang , Hongyu Wang , Wei Jiang , Jean-Pierre Boeuf View PDF HTML (experimental) Abstract: The first 3D kinetic simulation of a magnetron discharge reproduces the measured rotating spoke and reveals that density and current rotate in opposite directions: the $m=1$ spoke turns in the $\mathbf{E}\times\mathbf{B}$ direction at 90~kHz while $m\simeq16$ electron-cyclotron-drift-type filaments turn at 1.0~MHz, with no net propagation along $\mathbf{B}$. Magnetic drifts exchange far more energy than they deposit, yet their spoke-front heating sustains the ionization. Following helical paths, the anode-directed current is relayed by de-trapping turbulence at the sheath edge (50\%) and by the spoke channel in the bulk (97\%).
