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…
High repetition rate (>= kHz) targets and optics from liquid microjets for the study and application of high intensity laser-plasma interactions
K. M. George, J. T. Morrison, S. Feister +11
High intensity laser-plasma interactions produce a wide array of energetic particles and beams with promising applications. Unfortunately, high repetition rate and high average pow…
Relativistic laser driven electron accelerator using micro-channel plasma targets
Joseph Snyder, Liangliang Ji, Kevin M. George +11
We present an experimental demonstration of the efficient acceleration of electrons beyond 60 MeV using micro-channel plasma targets. We employed a high-contrast, 2.5 J, 32 fs shor…
Microengineering laser plasma interactions at relativistic intensities
S. Jiang, L. L. Ji, H. Audesirk +8
We report on the first successful proof-of-principle experiment to manipulate laser-matter interactions on the microscale using highly ordered Si microwire arrays. The interaction…
Liquid crystal films as on-demand, variable thickness (50-5000 nm) targets for intense lasers
P. L. Poole, C. D. Andereck, D. W. Schumacher +6
We have developed a new type of target for intense laser-matter experiments that offers significant advantages over those currently in use. The targets consist of a liquid crystal…
