Instability-enhanced transport in low temperature magnetized plasma

International audienceIt is shown that the transport in low temperature, collisional, bound plasma is enhanced by instabilities at a high magnetic field. While themagnetic field confines the electrons in a stable plasma, the instability completely destroys the confinement such that the transport becomesindependent of the magnetic field in the highly magnetized limit. An analytical expression of the instability-enhanced collision frequency isproposed, based on a magnetic field independent edge-to-center density ratio
