The high intensity light ion source (SILHI) is an ECR ion source operating at 2.45 GHz which produces high intensity (over 100 mA) proton or deuteron beams at 95 keV. This encouraged us to propose a permanent magnet source based on the SILHI design to fit in with the injector of the Spiral 2 project, requesting 5 mA of D+ beam with an energy of 40 keV and a normalized rms emittance lower than 0.2 π mm.mrad. The new source has been recently assembled and the first beam (proton) extracted. The source design improvements and the preliminary results are reported. |
