抄録

A multi-pass Thomson scattering (TS) system has the advantage of enhancing scattered signals. We constructed a multi-pass TS system modeled on the GAMMA 10 TS system; the new system has a polarization-based configuration with an image relaying system. For the first time, we used the new system to measure electron temperatures in the GAMMA 10 plasma. By using the multi-pass TS system with four passes, the integrated scattering signal was magnified by approximately a factor of three.
