Weibel instability beyond bi-Maxwellian anisotropy
Thales Silva, Bedros Afeyan, Luis O. Silva
The shape of the anisotropic velocity distribution function, beyond the realm of strict Maxwellians can play a significant role in determining the evolution of the Weibel instabili…
Optimal Control of Laser-Plasma Instabilities Using Spike Trains of Uneven Duration and Delay: STUD Pulses
Bedros Afeyan, Stefan Hüller
Adaptive methods of laser irradiation of plasmas are proposed consisting of deterministic, `on-off' amplitude modulations in time, and intermittently changing speckle-patterns. The…
Vlasov on GPU (VOG Project)
M. Mehrenberger, C. Steiner, L. Marradi +3
This work concerns the numerical simulation of the Vlasov-Poisson set of equations using semi- Lagrangian methods on Graphical Processing Units (GPU). To accomplish this goal, modi…
Wavelets, Curvelets and Multiresolution Analysis Techniques in Fast Z Pinch Research
Bedros Afeyan, Kirk Won, Jean Luc Starck +1
Z pinches produce an X ray rich plasma environment where backlighting imaging of imploding targets can be quite challenging to analyze. What is required is a detailed understanding…
Wavelets, Curvelets and Multiresolution Analysis Techniques Applied to Implosion Symmetry Characterization of ICF Targets
Bedros Afeyan, Kirk Won, Jean Luc Starck +1
We introduce wavelets, curvelets and multiresolution analysis techniques to assess the symmetry of X ray driven imploding shells in ICF targets. After denoising X ray backlighting…
Optical Mixing Controlled Stimulated Scattering instabilities: Suppression of SRS by the Controlled Introduction of Ion Acoustic and Electron Plasma Wave Turbulence
Bedros Afeyan, M. Mardirian, K. Won +4
In a series of experiments on the Omega laser facility at LLE, we have demonstrated the suppression of SRS in prescribed spectral windows due to the presence of externally controll…
