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

2017

International audience; The effect of double frequency heating on the performance of the CERN GTS-LHC 14.5 GHz ElectronCyclotron Resonance (ECR) ion source in afterglow mode is reported. The source of the secondary microwave frequency was operated both in pulsed and continuous wave (CW) modes within the range of 12–18 GHz. The results demonstrate that the addition of the secondary frequency can significantly impact the extracted beam currents and the temporal stability of the beam during the afterglow discharge. For example, up to a factor of 2.6 increase was achieved for 208Pb35+ and a factor of 3.1 for 208Pb37+ compared to single frequency afterglow currents. It is shown that these effect…
