dc electrical conductivity in strongly magnetized plasmas
Scott D. Baalrud, Trevor Lafleur
A generalized Ohm's law is derived to treat strongly magnetized plasmas in which the electron gyrofrequency significantly exceeds the electron plasma frequency. The frictional drag…
Friction Force in Strongly Magnetized Plasmas
David J. Bernstein, Trevor Lafleur, Jerome Daligault +1
A charged particle moving through a plasma experiences a friction force that commonly acts antiparallel to its velocity. It was recently predicted that in strongly magnetized plasm…
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…
Electron power absorption in low pressure capacitively coupled electronegative oxygen radio frequency plasmas
Máté Vass, Sebastian Wilczek, Trevor Lafleur +3
A thorough understanding of the energy transfer mechanism from the electric field to electrons is of utmost importance for optimization and control of different plasma sources and…
Transverse Force Induced by a Magnetized Wake
Trevor Lafleur, Scott D Baalrud
The force on a test charge moving through a strongly magnetized plasma is calculated using linear response theory. Strong magnetization is found to generate a component of the forc…
The effect of alternative propellants on the electron drift instability in Hall-effect thrusters: Insight from 2D Particle-In-Cell simulations
Vivien Croes, Antoine Tavant, Romain Lucken +4
Hall-effect thrusters (HETs) operated with xenon are one of the most commonly used electric propulsion technologies for a wide range of space missions, including drag compensation…
