Heavy ion beam acceleration in the first three cryomodules at the Facility for Rare Isotope Beams at Michigan State University
The Facility for Rare Isotope Beams (FRIB) being constructed at Michigan State University [J. Wei et al., The FRIB superconducting linac—status and plans, LINAC’16, Lansing, MI, p. 1, http://accelconf.web.cern.ch/AccelConf/linac2016/papers/mo1a01.pdf] is based on a cw superconducting linear accelerator which is designed to deliver unprecedented 400 kW heavy ion beam power to the fragmentation target. The installation of the accelerator equipment is approaching completion and multistage beam commissioning activities started in the summer of 2017 with expected completion in 2021. A room-temperature test electron cyclotron resonance ion source, ARTEMIS, provided argon and krypton beams for the commissioning of the low energy beam transport, a radio frequency quadrupole (RFQ), the medium energy beam transport (MEBT) and the first three accelerating cryomodules. The commissioning of the first linac segment (LS1), composed of 15 cryomodules, is planned in the spring of 2019. This paper describes the first results of experimental beam dynamics studies in the LEBT, RFQ, MEBT and the first three cryomodules with comparison to the numerical simulations.
