Measurements on Fast switches and combiners (FADIS-BC) for High-Power Millimeter-wave beams based on dielectric beam splitters

EPJ Web of Conferences, 2012
An upgraded version of a quasi-optical diplexer combiner, based on a resonating system coupling two transmission lines using three Dielectric Beam Splitters, has been realized and tested.

An algorithm to enhance the capability of imaging Thomson scattering

AIP Advances
Collective Thomson scattering (TS) is a powerful technique to accurately diagnose the parameters of laser-produced plasmas. However, when the scattering parameter α, which is inverse to the product of electron Debye length and wavenumber of plasma ...

Thomson scattering techniques in laser produced plasmas [PDF]

, 2006
Thomson scattering has been shown to be a valuable technique for measuring the plasma conditions in laser produced plasmas. Measurement techniques are discussed that use the ion-acoustic frequency measured from the collective Thomson-scattering spectrum ...

Study of the spatial growth of stimulated Brillouin scattering in a gas-filled hohlraum via detecting the driven ion acoustic wave

Matter and Radiation at Extremes
In an experiment performed on the Shenguang-III prototype laser facility, collective Thomson scattering (TS) is used to study the spatial growth of stimulated Brillouin scattering (SBS) in a gas-filled hohlraum by detecting the SBS-driven ion acoustic ...

Observation of relativistic effects in collective Thomson scattering [PDF]

, 2009
We observe relativistic modifications to the Thomson scattering spectrum in a traditionally classical regime: v{sub osc}/c = eE{sub 0}/cm{omega}{sub 0} << 1 and T{sub e} < 1 keV.

3D dynamics of a premagnetized gas-puff Z-pinch implosion [PDF]

Matter and Radiation at Extremes
Gas-puff Z pinches are pulsed-power-driven plasma implosions used as compact laboratory sources of soft X rays and fusion neutrons and as a platform for magneto-inertial fusion research.
