Status report of the accelerator for multiply charged ions in Grenoble

The status report of the Multiply Charged Ion Accelerator of the CEA-Grenoble is presented. This facility is devoted to the production of multiply charged ions (up to Xe 31+ ) in the low energy domain (1–20 q keV ). A new 14.5 GHz high magnetic field electron cyclotron resonance ion source of the Caprice type has been installed, the transmission of the beam line increased, resulting in a large enhancement of the available beam intensity. Ion selection and deceleration are simplified. Emittances as low as before are achieved. Performances for various beams are presented, together with updated beam emittance measurements. The intensity enhancement is especially large for highly charged ion beams like Ar 17+ (100 times more intensity), and enables routine delivery to experiments of more than 10 μ A of Xe 25+ at 20 q keV in 20 π mm mrad . The range of available charge states was extended to Xe 31+ (with a reasonable intensity of 180 nA ). Future prospects include the extension of the energy range down to a few q eV .
