Mode transitions and spoke structures in ExB Penning discharge
M. Tyushev, M. Papahn Zadeh, N. S. Chopra +7
Two-dimensional particle-in-cell simulations in the (radial-azimuthal) plane perpendicular to the axial direction of a cylindrical ExB Penning discharge are presented. The low-pres…
Multimodal azimuthal oscillations in electron beam generated plasma
Nirbhav Singh Chopra, Mina Papahn Zadeh, Mikhail Tyushev +3
Electron beam (e-beam) generated plasmas with applied cross electric and magnetic fields are promising for low-damage material process…
The electron cyclotron drift instability: a comparison of particle-in-cell and continuum Vlasov simulations
Arash Tavassoli, Mina Papahn Zadeh, Andrei Smolyakov +2
The linear and nonlinear characteristics of the electron cyclotron drift instability (ECDI) have been studied through the particle-in-cell (PIC) and continuum Vlasov simulation met…
Azimuthal structures and turbulent transport in Penning discharge
M. Tyushev, M. Papahn Zadeh, V. Sharma +4
Azimuthal structures in cylindrical Penning discharge are studied with 2D3V radial-azimuthal PIC/MCC model with the axial magnetic field. The discharge is self-consistently support…
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…
