FIRST BEAM OF THE CEA-SACLAY CW HIGH- INTENSITY MICROWAVE

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 .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 2 ). A microwave power of 900 W at 2.45 GHz was needed. Diagnostic hardware, first beam measurements and last results are presented.
