Enhanced transport in magnetized low temperature discharges

International audienceMultiple 2D PIC simulations of a magnetized plasma discharge were performed to investigate the cross field plasma transport. Several regimes were identified with transitions depending on the coupled influence of the magnetic field and the collisions. At high magnetic field, a strong instability resulting from the interaction between a lower hybrid mode and an ion acoustic mode leads to a significant discrepancy with the plasma transport predicted by the classical theory. A simple fluid dispersion relation was successfully compared to the simulation data
