Ion temperature measurements in a tokamak by collective Thomson scattering of FIR laser radiation
A D(2)O FIR laser emitting 0.5J in 1.4 microsec at 385 1.0 E-6 m and a heterodyne receiver with a noise temperature of 8000 K (DSB) were used in a Thomson scattering experiment to measure the ion temperature of a tokamak plasma during a single laser shot. A series of measurements under reproducible plasma conditions were carried out in H-, D-, and He-plasmas. Their statistical analysis yielded a typical relative error of 25% for a single shot measurement.
