Ion collection by a conducting sphere in a magnetized or drifting collisional plasma
Ion collection by dust grains and probes in plasmas with a neutral background is of interest in the study of both space and terrestrial plasmas, where charge-exchange collisions can play an important role in ion collection. Further, background drifts or magnetic fields can significantly affect the …

Transition Flow in Edge Plasmas: Solution of the Two-Fluid Region With Sources
… context of the transition flow between highly collisional plasma and collisionless sheath, the linearized Fokker-Planck equation for the ions, in an intermediate collisionality region, is generalized to include an arbitrary source function. Nonisentropic effects due to the source function …

Experimental Characterization of Diffusive Phenomena in Multi-Ion-Species Plasma Shocks Formed During Railgun-Driven Plasma Jet Collision Events
… is a transport process which can occur in plasma shocks. Experimental observations of this phenomena are difficult to make, but are of interest to ongoing Inertial Confinement Fusion efforts. This body of work describes the results of two major experimental campaigns conducted at Virginia …

Modeling gap closure within vaporizing transmission lines of pulsed power machines using particle-in-cell direct simulation Monte Carlo (PIC-DSMC)
… more resolution due to the high density highly collisional plasma layer that forms microns from the cathode surface while the electromagnetic (EM) field solve can be handled with a coarser grid.

Multi-wavelength observations of sprites over southern Africa
… energy distribution function in collisional plasma, the average characteristic electron energies and the strength of the electric fields in sprites were estimated as 5.5 eV and 150 V/m respectively, which were comparable to those inferred from space-based observations. The charge …

Radiatively Cooled Magnetic Reconnection Experiments Driven by Pulsed Power
… is a ubiquitous process in astrophysical plasmas, responsible for the explosive conversion of magnetic energy into thermal and kinetic energy. In extreme astrophysical systems, such as black hole coronae and neutron star magnetospheres, radiative cooling modifies the energy partition by …
