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…
