Abstract

The ability of Electron Cyclotron Resonance (ECR) Ion Sources to produce relatively high current ion beams of elements from across the periodic table has dramatically increased the capabilities of the world’s ion accelerators.  An essential step in furthering the capabilities of ECR sources is increasing the magnitude of the confining magnetic fields of these sources’ plasmas.  The world’s highest performing sources, like LBNL’s VENUS, employ NbTi coils for this confinement, but further advances will require novel coil design and/or replacing the NbTi coils used in the highest-performing current sources with advanced superconductors.  This presentation will focus on what the ECR ion source community knows (and thinks it knows) about source design and optimization based on over 50 years of experience, as well as the challenges we will face as we move to higher-field sources.
