Visible light spectrometry measurements for studying an ECRIS plasma and especially applied to the MONO1001 ion source

Abstract

International audienceThe cylindrical geometry of the magnetic confinement of the MONO1001 ECR ion sourcemade in GANIL1, allows us to measure radial characteristics of the working ECR plasmawith Helium gas. The physical and the geometrical characteristics of the resonance surfaceinside the working ECR source have been quantified with the help of a visible lightspectrometer. Hence, we have deduced a shape of the ECRIS resonance surface whichcorresponds closely to our magnetic calculations
