Backward waves in the nonlinear regime of the Buneman instability
Arash Tavassoli, Magdi Shoucri, Andrei Smolyakov +2
Observation of low- and high-frequency backward waves in the nonlinear regime of the Buneman instability is reported. Intense low-frequency backward waves propagating in the direct…
The role of noise in PIC and Vlasov simulations of the Buneman instability
Arash Tavassoli, Oleksandr Chapurin, Marilyn Jimenez +7
The effects of noise in particle-in-cell (PIC) and Vlasov simulations of the Buneman instability in unmagnetized plasmas are studied. It is found that, in the regime of low drift v…
Nonlinear regimes of the electron cyclotron drift instability in Vlasov simulations
Arash Tavassoli, Andrei Smolyakov, Magdi Shoucri +1
We report on a novel investigation of the nonlinear regime of the electron cyclotron drift instability, using a grid-based Vlasov simulation. It is shown that the instability occur…
Ion Temperature Effects on Plasma Flow in the Magnetic Mirror Configuration
A. Sabo, A. I. Smolyakov, P. Yushmanov +1
Effects of finite ion temperature on plasma flow in the converging-diverging magnetic field, the magnetic mirror, or equivalently, magnetic nozzle configuration, are studied using…
On the mechanism of ionization oscillations in Hall thrusters
O. Chapurin, A. Smolyakov, G. Hagelaar +1
Low frequency ionization oscillations involving plasma and neutral density (breathing modes) are the most violent perturbations in Hall thrusters for electric propulsion. Because o…
On Quasineutral Plasma Flow in the Magnetic Nozzle
A. I. Smolyakov, A. Sabo, P. Yushmanov +1
Exact solutions for quasineutral plasma acceleration of magnetized plasma in the paraxial magnetic nozzle are obtained. It is shown that the non-monotonic magnetic field with a loc…
