Obeservation of a forbidden line of FeXX and its application for ion temperature measurements in the PLT tokamak
A spectrum line in the PLT tokamak discharges, with wavelength measured as 2665.1 +- 0.3A, has been identified as the 2s/sup 2/2p/sup 3/ /sup 2/D/sub 5/2/ ..-->.. /sup 2/D/sub 3/2/ magnetic dipole transition in the FeXX ground configuration. A variety of localized spectroscopic diagnostics, e.g., ion temperature and density distribution measurements in the high-temperature interior of the plasma, are feasible by means of forbidden lines of this type. The 2665A line has been used to measure near-central ion temperature in a discharge with auxiliary neutral beam heating.
