Research Abstract |
A novel configuration of the multi-pass Thomson scattering (TS) system is proposed to improve the time resolution and accuracy of electron temperature measurements by use of a polarization control technique and the image relay optics. This configuration can realize a perfect coaxial multi-passing at each pass, and the number of round trips is not limited by the optical configuration. To confirm the feasibility of the new method, we installed this system in the GAMMA 10 and Large Helical Device. We have confirmed the multi-pass scattering signal from the plasma. These results are in good agreement with the design.
