Doppler-Broadening Measurements of X-Ray Lines for Determination of the Ion Temperature in Tokamak Plasmas

摘要

The ion-temperature results are deduced from Doppler-broadening measurements of the Ka (ls-2p) resonance line emitted from helium-like iron impurity ions in the hot central core of PLT (Princeton Large Torus) tokamak discharges. The measurements were performed using a high resolution Bragg crystal spectrometer with a multiwire proportional counter.
