First beam of the CEA-Saclay CW high-intensity microwave source

The High Intensity Light Ion Source SILHI is designed to be a prototype source for high power proton and deuteron accelerators. The aim is to achieve beam currents greater than 100 mA at 95 keV with rms normalized emittance lower than 0.2 /spl pi/.mm.mrad. Installed at CEA Saclay, this ECR source delivered its first proton beam in July 1996. In February 1997, a 107 mA CW beam has been extracted through a 8 mm diameter extraction aperture (J=213 mA/cm/sup 2/). A microwave power of 900 W at 2.45 GHz was needed. Diagnostic hardware, first beam measurements and last results are presented.
