Název v původním jazyce

Phase control of a z-current-driven plasma column

Popis výsledku v původním jazyce

A dynamic mitigation is presented for sausage and kink instability growths of a z-current-driven magnetized plasma column. In this Rapid Communication we found that a wobbling motion of the z-current electron axis induces a phase-controlled perturbation, so that the growths of the sausage and kink instabilities are successfully and remarkably mitigated. In general, plasma instabilities emerge from perturbations, and the perturbation phase is normally unknown. However, if the perturbation phase is known or actively imposed by, for example, a designed driver wobbling behavior, the instability growth would be controlled and mitigated by a superimposition of the perturbations imposed. The results in this Rapid Communication demonstrate that the wobbling z-current electron beam would provide an improvement in the plasma column stability and uniformity.
