Electron cyclotron resonance sources of multiply charged ions. Latest developments at Grenoble

The behavior of compact electron cyclotron resonance ion sources (ECRIS) is emphasized in this article, and more specifically the Caprice ECRIS concept: a high B field (/spl ges/1 T) source offering good performances both in extracted ion charge states and intensities, in a rather small volume, a source easy to handle and to operate. This concept like the ECRIS concept itself originated from the Grenoble group; it is quite attractive to continuous regime cyclotrons requiring high stability ion beams, but it is also well suited to delivering very high intensity particle pulses (today a few p/spl mu/A of Pb/sup 28+/ or Au/sup 27+/ ion beams, a few ms long) of interest for synchrotron bunching. Finally the developments and activities in the field of ECRIS at Grenoble, are shortly surveyed while giving some trends and prospects.<<ETX>>
