Effect of double frequency heating on the lead afterglow beam currents of an electron cyclotron resonance ion source

Physical Review Accelerators and Beams, 2017
The effect of double frequency heating on the performance of the CERN GTS-LHC 14.5 GHz Electron Cyclotron Resonance (ECR) ion source in afterglow mode is reported. The source of the secondary microwave frequency was operated both in pulsed and continuous
