This paper presents recent developments of accelerator physics related topics for the Facility for Rare Isotope Beams (FRIB) being built at Michigan State University. While extensive beam dynamics simulations including all known errors do not show uncontrolled beam losses in the linac, ion beam contaminants extracted from the ECR ion source together with main ion beam can produce significant losses after the charge stripper. These studies resulted in development of beam collimation system at relatively low energy of 16 MeV/u and room temperature bunchers instead of originally planned superconducting ones. Commissioning of the Front End enabled detailed beam physics studies accompanied with the simulations using several beam dynamics codes. Settings of beam optics devices from the ECR to MEBT has been developed and applied to meet important project milestones. Similar work is planned for the beam commissioning of the first 3 cryomodules in the superconducting linac.

FRXGBF3 Perspectives in High Intensity Heavy Ion Sources for Future Heavy Ion Accelerators ion-source, heavy-ion, ECR, electron 5047

  Driven by the development of next generation heavy ion accelerators such as IMP-HIAF, GSI-FAIR, RIKEN-RIBF, SPIRAL 2, JLEIC and so on that need very intense highly charged heavy ion beam injectors working at either pulsed or CW modes, intense research and development work towards more powerful ion sources have been made in different laboratories, which likewise has stimulated obvious advancement of the performances in recent years. However, even the best performing ion sources can't meet all the requirements. While the ion source researchers are tackling the next generation ion sources development, it is worth investigating the possibilities of other solutions, especially when very intense heavy ion beams are needed for the more intense and powerful heavy ion accelerators, for instance the driver accelerator to study inertial confinement fusion with heavy ion. This invited talk presents recent advancements of highly charged heavy ion sources, and discusses the other possible approaches for intense highly charged heavy ion beams for future heavy ion accelerators.
