Wave-driven countercurrent plasma centrifuge

Wave-driven countercurrent plasma centrifuge

A method for driving rotation and a countercurrent flow in a fully ionized plasma centrifuge is described. The rotation is produced by radiofrequency waves near the cyclotron resonance. The wave energy is transferred into potential energy in a manner similar to the α channeling effect. The countercurrent flow may also be driven by radiofrequency waves. By driving both the rotation and the flow ...

Particle in Cell-Monte Carlo Collisions of a Plasma Column Driven by Surface Wave Plasma Discharges

In this work, applicability of Particle in Cell-Monte Carlo Collisions (PIC-MCC) simulation method for better understanding of the plasma physical mechanisms and real important aspects of a plasma column driven by surface wave plasma discharges that is used in plasma antennas is examined. Via the implementation of geometry and physical parameters of the plasma column to an Object Oriented PIC-M...

Plasma instability of a vacuum arc centrifuge.

Ever since conception of the vacuum arc centrifuge in 1980, periodic fluctuations in the ion saturation current and floating potential have been observed in Langmuir probe measurements in the rotation region of a vacuum arc centrifuge. In this work we develop a linearized theoretical model to describe a range of instabilities in the vacuum arc centrifuge plasma column, and then test the validit...

Control of drift wave turbulence by driven plasma currents

Submitted for the DPP09 Meeting of The American Physical Society Control of drift wave turbulence by driven plasma currents OLAF GRULKE, CHRISTIAN BRANDT, STEFAN ULLRICH, KIAN RAHBARNIA, THOMAS KLINGER, MPI for Plasma Physics, EURATOM Association, D-17491 Greifswald — The anomalous transport in the plasma edge of fusion devices is believed to be dominated by the drift wave instability, which is...
