A laser‐induced fluorescence spectroscopy system was developed in a linear magnetized helicon plasma at Kyushu University. The thermal Doppler broadening on velocity distribution function follows the Maxwell distribution, and the averaged central ion temperature was evaluated to be ∼0.36 eV. The effect of Zeeman splitting was observed for a more accurate assessment of the measurement and is consistent with the calculation. The temperature ratio of electrons and ions, T i / T e , was evaluated to be ∼0.1. The result is valuable for evaluating the nonlinear processes of the plasma turbulence. © 2019 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
