Drift-cyclotron loss-cone instability in 3D simulations of a sloshing-ion simple mirror
Aaron Tran, Samuel J. Frank, Ari Y. Le +11
The kinetic stability of collisionless, sloshing beam-ion (45° pitch angle) plasma is studied in a 3D simple magnetic mirror, mimicking the Wisconsin High-temperature superconducto…
Hybrid-VPIC: an Open-Source Kinetic/Fluid Hybrid Particle-in-Cell Code
Ari Le, Adam Stanier, Lin Yin +3
Hybrid-VPIC is an extension of the open-source high-performance particle-in-cell (PIC) code VPIC incorporating hybrid kinetic ion/fluid electron solvers. This paper describes the m…
Hybrid Paricle-in-Cell Simulations of Electromagnetic Coupling and Waves From Streaming Burst Debris
Brett D. Keenan, Ari Le, Dan Winske +4
Various systems can be modeled as a point-like explosion of ionized debris into a magnetized, collisionless background plasma -- including astrophysical examples, active experiment…
Astrophysical explosions revisited: collisionless coupling of debris to magnetized plasma
Ari Le, Dan Winske, Adam Stanier +4
The coupling between a rapidly expanding cloud of ionized debris and an ambient magnetized plasma is revisited with a hybrid (kinetic ion/fluid electron) simulation code that allow…
A drift kinetic model for the expander region of a magnetic mirror
Blake A. Wetherton, Ari Le, Jan Egedal +4
We present a drift kinetic model for the free expansion of a thermal plasma out of a magnetic nozzle. This problem relates to plasma space propulsion systems, natural environments…
A drift-kinetic method for obtaining gradients in plasma properties from single-point distribution function data
Blake A. Wetherton, Jan Egedal, Peter K. Montag +2
In this paper, we derive a new drift-kinetic method for estimating gradients in the plasma properties through a velocity space distribution at a single point. The gradients are int…
Spacecraft observations and analytic theory of crescent-shaped electron distributions in asymmetric magnetic reconnection
J. Egedal, A. Le, W. Daughton +8
Supported by a kinetic simulation, we derive an exclusion energy parameter providing a lower kinetic energy bound for an electron to cross from one inflow region to the…
