Development of the MARS-D ECR ion source, a 45 GHz next generation ECRIS using a NbTi MARS-magnet, has been continuously moving forward at LBNL. Recent stress analyses and other key components of the MARS-D ion source have been essentially finalized. This article presents and discusses the status of this new 45 GHz ECR ion source, such as the latest design features and the fabrication plan with funding available in the very near future.

TUXZO01 A Proposed Explanation of High-Minimum-B Instabilities 68

  It is well-known that electron cyclotron resonance ion sources exhibit instabilities when these sources’ minimum magnetic fields are approximately 80% of the resonant field or greater, but the reasons for this instability have yet to be satisfactorily explained. We show that raising the minimum field makes much faster heating modes accessible at lower energies that invite the onset of kinetic instabilities.
