Accelerator Seminar - Eduard Pozdeyev: FRIB Linac design, construction and commissioning

FRIB Linac design, construction and commissioning

ABSTRACT

The Facility for Rare Isotope Beams (FRIB) is the DOE SC Nuclear Physics user facility developed at Michigan State University as a cooperative agreement between DOE and MSU. The project was awarded to MSU in 2008, met its KPPs a year ago, and started operating for users in May of 2022. The FRIB Superconducting CW driver linac is designed to accelerate all stable ions including uranium to energies above 200 MeV/u with 46 cryomodules containing 324 quarter-wave resonators (QWR) and half-wave (HWR) resonators. In this talk, I’ll give an overview of the FRIB linac design, summarize the experience with project construction, and describe the commissioning of the linac. I’ll explain the reasoning for some design choices and point out analogies with other hadron linacs where appropriate.
