Perspectives on Physics of ExB Discharges Relevant to Plasma Propulsion and Similar Technologies
Igor D. Kaganovich, Andrei Smolyakov, Yevgeny Raitses +22
This paper provides perspectives on recent progress in the understanding of the physics of devices where the external magnetic field is applied perpendicularly to the discharge cur…
Scaling of Spoke Rotation Frequency within a Penning Discharge
Andrew T. Powis, Johan A. Carlsson, Igor D. Kaganovich +2
A rotating plasma spoke is shown to develop in two-dimensional full-sized kinetic simulations of a Penning discharge cross-section. Electron cross-field transport within the discha…
Validation and benchmarking of two particle-in-cell codes for a glow discharge
Johan Carlsson, Alexander Khrabrov, Igor Kaganovich +2
The two particle-in-cell codes EDIPIC and LSP are benchmarked and validated for a parallel-plate glow discharge in helium, in which the axial electric field had been carefully meas…
Amplification due to Two-Stream Instability of Self-Electric and Magnetic Fields of an Ion Beam Propagating in Background Plasma
Erinc K. Tokluoglu, Igor D. Kaganovich, Johan A. Carlsson +2
Propagation of charged particle beams in background plasma as a method of space charge neutralization has been shown to achieve a high degree of charge and current neutralization a…
Particle-in-cell simulations of anomalous transport in a Penning discharge
Johan Carlsson, Igor Kaganovich, Andrew Powis +3
Electrostatic particle-in-cell simulations of a Penning discharge are performed in order to investigate azimuthally asymmetric, spoke-like structures previously observed in experim…
The hypersecant Jacobian approximation for quasi-Newton solves of sparse nonlinear systems
Johan Carlsson, John R. Cary
A new Jacobian approximation is developed for use in quasi-Newton methods for solving systems of nonlinear equations. The new hypersecant Jacobian approximation is intended for the…
