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 analysis of both electron temperature and density are performed by two methods–a constant chisquare boundaries method and a Monte Carlo simulation, determining asymmetrical error bars for the electron temperature.
