摘要

A laser Thomson scattering (LTS) system developed in the MAP (material and plasma) -IIrnsteady-state linear divertor/edge plasma simulator at the University of Tokyo, intended for thernstudy of low-temperature recombining plasmas, is presented. The electron temperature (Te) at thernentrance of the recombination front of He electron-ion recombining (EIR) plasma was determinedrnto be as low as 0.15 eV. An electron temperature of 0.05 eV, which was previously determinedrnbased on the Rydberg series spectra of He I at the brightest point of the recombining front, can bernconsidered to be a plausible value. Possible effects leading to an error in the estimation of thernparameters in low-temperature plasma were evaluated, leading to the conclusion that these effectsrnare negligible.
