Abstract

Polarimetry diagnostic for International Thermonuclear Experimental Reactor (ITER) considered among the tools to measure and, thus, to provide ability to control the thermonuclear plasma in the next generation fusion device. The shortage of the reliable sources in the short wavelength far infrared (FIR) region suggests to use common CH3OH oscillation line. Recently new laser sources became available at 50 μm FIR region. Proposed system unveil the alternative possibilities apart from 118.8 μm poloidal polarimeter for ITER. This system, which introduces 47.6 and 57.2 oscillation lines of CO2-laser pumped CH3OD laser inherits all well documented features from it 118.8 μm predecessor will shows the clear advantages to utilize shorter wavelength radiation for plasma probing.
