Abstract

A compact Nd:YAG laser Thomson scattering system was constructed and applied to the TST-2 spherical tokamak in order to measure the electron temperature and the electron density. A large solid angle (∼35 msr) was achieved by use of a compact Newtonian mirror system for the collection optics. Absolute calibration was performed by Rayleigh scattering. An electron temperature increase from 140 eV to 210 eV was observed upon injection of 200 kW of RF power.
