Advanced Thomson scattering system for high-flux linear plasma generator

High sensitivity imaging Thomson scattering for low temperature plasma.

A highly sensitive imaging Thomson scattering system was developed for low temperature (0.1-10 eV) plasma applications at the Pilot-PSI linear plasma generator. The essential parts of the diagnostic are a neodymium doped yttrium aluminum garnet laser operating at the second harmonic (532 nm), a laser beam line with a unique stray light suppression system and a detection branch consisting of a L...

New High Resolution Thomson Scattering System for the COMPASS Tokamak

The COMPASS tokamak is being re-installed at IPP Prague after its transfer from Culham, U.K. Within the innovation, new diagnostics will be constructed, including a High Resolution Thomson Scattering System measuring electron temperature (Te) and electron density (ne) profiles. Scientific programme of the COMPASS tokamak is focused on the pedestal studies, thus the main stress will be laid on t...

High-resolution Thomson scattering system on the COMPASS tokamak: evaluation of plasma parameters and error analysis.

The electron density and temperature profiles measured by the Thomson scattering diagnostic on the COMPASS tokamak are used for estimation of electron kinetic energy, energy confinement time, and effective charge number Z(eff). Data are compared with the line-integrated electron density measured by a microwave interferometer in an ohmically heated plasma with a circular cross section. An error ...

Thomson scattering from a three-component plasma.

A model for a three-component plasma consisting of two distinct ionic species and electrons is developed and applied to study x-ray Thomson scattering. Ions of a specific type are assumed to be identical and are treated in the average-atom approximation. Given the plasma temperature and density, the model predicts mass densities, effective ionic charges, and cell volumes for each ionic type, to...
