A Particle-In-Cell Code Comparison for Ion Acceleration: EPOCH, LSP, and WarpX
Joseph R. Smith, Chris Orban, Nashad Rahman +3
There are now more Particle-in-Cell (PIC) codes than ever before that researchers use to simulate intense laser-plasma interactions. To date, there have been relatively few direct…
Optimizing Laser-Plasma Interactions for Ion Acceleration using Particle-in-Cell Simulations and Evolutionary Algorithms
Joseph R. Smith, Chris Orban, John T. Morrison +4
The development of ultra-intense laser-based sources of high energy ions is an important goal, with a variety of potential applications. One of the barriers to achieving this goal…
Experimental observation and computational modeling of radial Weibel instability in high intensity laser-plasma interactions
Gregory K. Ngirmang, John T. Morrison, Kevin M. George +5
When a relativistic intensity laser interacts with the surface of a solid density target, suprathermal electron currents are subject to Weibel instability filamentation when propag…
Particle-in-Cell Simulations of Density Peak Formation and Ion Acceleration from Short Pulse Laser-Driven Ponderomotive Steepening
Joseph R. Smith, Chris Orban, Gregory K. Ngirmang +4
We use particle-in-cell (PIC) simulations and simple analytic models to investigate the laser-plasma interaction known as ponderomotive steepening. When normally incident laser lig…
