Ion kinetic effects and instabilities in the plasma flow in the magnetic mirror
Marilyn Jimenez, Andrei Smolyakov, Oleksandr Chapurin +1
Kinetic effects in plasma flow due to a finite ion temperature and ion reflections in a converging-diverging magnetic nozzle are investigated with collisionless quasineutral hybrid…
Fluid and hybrid simulations of the ionization instabilities in Hall thruster
Oleksandr Chapurin, Andrei Smolyakov, Gerjan Hagelaar +2
Low-frequency axial oscillations (5-50 kHz) stand out as a pervasive feature observed in many types of Hall thrusters. While it is widely recognized that the ionization effects pla…
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…
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…
Nonlinear structures and anomalous transport in partially magnetized plasmas
Salomon Janhunen, Andrei Smolyakov, Oleksandr Chapurin +3
Nonlinear dynamics of the electron-cyclotron instability driven by the electron current in crossed electric and magnetic field is studied. In nonlinear regime…
Generalized lower-hybrid mode with, density gradient, equilibrium ExB drift, collisions and finite electron Larmor radius: Numerical studies with MATLAB solver
Ivan Romadanov, Andrei Smolyakov, Winston Frias +2
MATLAB solver for general dispersion relation has been developed to study local instabilities in partially magnetized plasmas typical for ExB discharges. Several examples of the Si…
