Abstract Turbulence is ubiquitous in the universe and fluid dynamics. It influences a wide range of high energy density systems, from inertial confinement fusion to astrophysical-object evolution. Understanding this phenomenon crucial, however, due limitations experimental numerical methods plasma complete description turbulent spectrum still lacking. Here, we present measurement down micron sc...

Introduction Laser–plasma interaction (LPI) processes taking place in indirectand direct-drive targets differ significantly in several ways. Plasma electron densities ne in hohlraum targets are typically a few percent of the critical density n m e c e = ω π 0 2 2 4 , so that the main instability mechanisms are stimulated Raman and stimulated Brillouin scattering (SRS and SBS, respectively), whi...

 In this paper we have used plasma electron cyclotron emissions at the second harmonic frequency of extraordinary mode to determine the temperature profile of the plasma produced in IR-T1 Tokamak. The emissions obtained at different frequencies by a 5-channel heterodyne receiver, have been analyzed to determine the spatial variation of the electron temperature on the plasma cross section. The r...

Plasma-assisted electron-beam evaporation leads to changes in the crystallinity, density, and stresses of thin films. A dual-source plasma system provides stress control of large-aperture, high-fluence coatings used in vacuum for substrates 1m in aperture.
