On the Use of Spectral Lines Emitted by Carbon Ions for Plasma Diagnostics in Magnetic Fusion Devices.

Profiles of the n = 5-6 (λ = 4658 Å) and n = 6-7 (7726 Å) lines emitted by Li-like carbon C+3 ions have been computed for plasma conditions of tokamak and stellarator divertors (Ne = 1019–1021 m-3, Te = 1–10 eV). The broadening and profiles of these lines are proposed to be used for plasma diagnostic purposes in particular to crosscheck the validity of the plasma parameters determined from the CIV line intensities measured in JT-60U tokamak.
