Direct evidence of the gradient drift instability being the origin of a rotating spoke in a crossed field plasma
Liang Xu, Denis Eremin, Ralf Peter Brinkmann
A plasma rotating spoke in a crossed field discharge is studied using 2D radial-azimuthal fully kinetic Particle-In-Cell Monte Carlo Collision (PIC/MCC) simulations. The kinetic mo…
Self-acceleration and energy channeling in the saturation of the ion-sound instability in a bounded plasma
Liang Xu, Andrei Smolyakov, Salomon Janhunen +1
A novel regime of the saturation of the Pierce-type ion-sound instability in bounded ion-beam-plasma system is revealed in 1D PIC simulations. It is found that the saturation of th…
Analytical model of three regimes of cold cathode breakdown in helium
Liang Xu, Alexander V. Khrabrov, Igor D. Kaganovich +1
An analytical model has been developed to map out the low-pressure (left-hand) branch of the Paschen curve at very high voltage when electrons are in the runaway regime and charge…
