FIRST COMMISSIONING RESULTS OF THE SUSI ECRIS

A fully superconducting ECR ion source (ECRIS), SuSI (Superconducting Source for Ions) was constructed at the National Superconducting Cyclotron Laboratory at Michigan State University (NSCL/MSU) to replace the existing SC-ECRIS. This ECRIS operates at 18+14.5 GHz microwave frequencies. During the initial commissioning of the magnet, the axial field reached 3.6 T and 2.2 T at the injection and extraction, respectively. The radial field reached 2 T at the plasma chamber walls. These magnetic field values will be needed for a planned upgrade to 24-28 GHz in the second phase of commissioning. The first commissioning results of this new ECRIS are presented.
