Abstract

The light intensity of (6)Li III line spectrum at λ = 516.7 nm was observed during (6)Li(3+) beam tuning at the Hyper-Electron Cyclotron Resonance (ECR) ion source. Separation of ion species of the same charge to mass ratio with an electromagnetic mass analyzer is known to be an exceptionally complex process. However, (6)Li III line intensity observation conducted in this study gives new insights into its simplification of this process. The light intensity of (6)Li III line spectrum from the ECR plasma was found to have a strong correlation with the extracted (6)Li(3+) beam intensity from the RIKEN Azimuthal Varying Field cyclotron.
