A time-resolving spectrograph has been used to survey the forbidden magnetic dipole emissions of titanium, vanadium, chromium, iron, and nickel ions injected into the TFR (Tokamak de Fontenay-aux-Roses) plasma. A number of magnetic dipole transitions within the n = 2 ground configuration of the isoelectronic sequences from FI to BI were identified in the tokamak spectra; in some cases, experimental values of the wavelength were measured for the first time. The spectrograph had a photoelectric multispectral detector and a calibrated linear photometric sensitivity; thus, reliable determinations of the brightnesses in typical tokamak discharges could be made for these lines.
