Abstract：
In the beginning of the 90s, T. Taylor and his collaborators demonstrated ECR sources operating at low frequency (i.e. 2.45GHz) are able to produce very intense single charge light ion beams.
At CEA/Saclay, the SILHI source developments started in 1995. Since 1997 more than 100mA proton or deuteron beams are routinely produced in pulsed or continuous mode. To comply with ADS reliability constraint, important improvements have been performed to increase the installation reliability. Moreover, to optimize the beam transport in the low energy beam line, the extraction system was carefully designed and space charge compensation studies were undertaken. An important step has been reached in 2005 with the development of a permanent magnet source able to produce a total beam of 109mA at 85kV.
A new test bench named BETSI, especially dedicated to permanent magnet source developments, is presently under construction. It will allow analysing positive or negative extracted beams up to 50keV and 100mA.
In addition, for several years work has been done to optimize the production of negative hydrogen ion beam with such an ECR source. Recent analysis pushed towards the construction of a new set up based on a multicusp magnetic configuration.
After a brief overview of the CEA/Saclay source developments, this article will point out on the recent results and present status.
