Status Report Of The Nscl/Msu Ecr Ion Sources

Since the last ECR Workshop, NSCL/MSU has been involved in a vigorous ECR ion source R&D program, which resulted in the construction of an off-line test ECR ion source (ARTEMIS-B) for new beam development and ion optics studies. Also the design and partial completion of a 3rd generation, fully superconducting ECR ion source, SuSI has been accomplished. This paper is an overview of the construction projects and the different R&D activities performed with the existing ion sources. These activities include development of metallic ion beam production methods using evaporation with resistive and inductive ovens and sputtering of very refractory metals. Ion optics developments include testing different focusing elements (magnetic solenoid lens, electrostatic quadrupole triplet lens, Einzel lens, electrostatic double doublet quadrupole combined with an octupole lens), and different beam forming and diagnostics devices. The detailed results will be presented at the workshop in separate talks and posters.
