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…
Using Virtual Reality in Electrostatics Instruction: The Impact of Training
Chris D. Porter, Joseph R. H. Smith, Eric M. Stagar +5
Recent years have seen a resurgence of interest in using Virtual Reality (VR) technology to benefit instruction, especially in physics and related subjects. As VR devices improve a…
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…
A Hybrid Approach for Using Programming Exercises in Introductory Physics
Chris Orban, Richelle M. Teeling-Smith, Joseph R. H. Smith +1
Incorporating computer programming exercises into introductory physics is a delicate task that involves a number of choices that may have an effect on student learning. We present…
A controlled study of stereoscopic virtual reality in freshman electrostatics
Joseph R. Smith, Amber Byrum, Timothy M. McCormick +3
Virtual reality (VR) has long promised to revolutionize education, but with little follow-through. Part of the reason for this is the prohibitive cost of immersive VR headsets or c…
