A 20-chord Doppler spectrometer is used on the START spherical tokamak to record charge-exchange recombination ͑CXR͒ spectra ͑C 5ϩ 5291 Å, nϭ8→7͒. "Passive" radiation, mostly from near the plasma edge, is also present, and comes from electron-impact excitation of C 5ϩ as well as C 6ϩ CXR due to thermal neutrals. The relatively wide neutral beam, together with the blending of the passive and active emission, present difficult unfolding problems. These are overcome by imposing physics constraintsdoi:10.1063/1.1149471 fatcat:buscctplm5er5lvfssdpzl2yti
