Effects of particle-induced electron emission on transport properties in electrically-biased plasma sheaths under fusion-relevant conditions
Lucio Murillo, Chirag Skolar, Kolter Bradshaw +1
A rigorous implementation of energy-dependent ion- and electron-induced electron emission in a continuum-kinetic framework is used to reveal their effects on the scaling of plasma…
Capturing Secondary Kinetic Instabilities in Three-Dimensional Dayside Reconnection Using an Improved Gradient-Based Closure
Kolter Bradshaw, Ammar Hakim, James Juno +3
Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower-hybrid dr…
General kinetic ion induced electron emission model for metallic walls applied to biased Z-pinch electrodes
Chirag R. Skolar, Kolter Bradshaw, Manaure Francisquez +3
A kinetic ion induced electron emission (IIEE) model for general applications is developed to obtain the emitted electron energy spectrum for a distribution of ion impacts on a met…
Effects of oxidation and impurities in lithium surfaces on the emitting wall plasma sheath
Kolter Bradshaw, Ammar Hakim, Bhuvana Srinivasan
Use of lithium as a surface coating in fusion devices improves plasma performance, but the change in wall properties affects the secondary electron emission properties of the mater…
Energy-dependent implementation of secondary electron emission models in continuum kinetic sheath simulations
Kolter Bradshaw, Bhuvana Srinivasan
The plasma-material interactions present in multiple fusion and propulsion concepts between the flow of plasma through a channel and a material wall drive the emission of secondary…
Continuum kinetic investigation of the impact of bias potentials in the current saturation regime on sheath formation
Chirag R. Skolar, Kolter Bradshaw, James Juno +1
In this work, we examine sheath formation in the presence of bias potentials in the current saturation regime for pulsed power fusion experiments. It is important to understand how…
Plasma sheath studies using a physical treatment of electron emission from a dielectric wall
Kolter Bradshaw, Petr Cagas, Ammar Hakim +1
When a plasma sheath forms next to a dielectric wall, material properties determine electron absorption and reflection from the surface, impacting the sheath formation and structur…
