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.
