Dense plasma heating by crossing relativistic electron beams
Physical Review E American Physical Society 95:1 (2016) 013211
Abstract:
Here we investigate, using relativistic fluid theory and Vlasov-Maxwell simulations, the local heating of a dense plasma by two crossing electron beams. Heating occurs as an instability of the electron beams drives Langmuir waves which couple nonlinearly into damped ion-acoustic waves. Simulations show a factor 2.8 increase in electron kinetic energy with a coupling efficiency of 18%. Our results support applications to the production of warm dense matter and as a driver for inertial fusion plasmas.Raman scattering for intense high orbital angular momentum harmonic generation
Optics InfoBase Conference Papers (2016)
Abstract:
We identify a mechanism, based on Raman scattering, to endow near-infrared laser beams with high orders of orbital angular momentum (OAM). In combination with high-harmonic generation, this could lead to very high OAM harmonics in the soft x-ray region.Prospects for Multi-kJ Plasma Amplifiers
