Abstract
A yttrium-aluminum-garnet Thomson scattering (TS) system was constructed and applied to the tandem mirror GAMMA 10 plasma to measure the electron temperature. A large solid-angle TS light-collection system was set using a spherical mirror system and a large numerical aperture of bundled optical fiber. A five-channel polychromator with avalanche silicon photo diodes was employed after being calibrated with standard light. Calibration was performed by Rayleigh and Raman scattering. An electron temperature increase from 40 eV to 80 eV was observed with application of electron cyclotron heating to plug/barrier cells.
