In 2008, Michigan State University was selected to establish the Facility for Rare Isotope Beams (FRIB). Construction of FRIB accelerator completed in January 2022. Phased commissioning with heavy ion beams started 2017 normal-conducting source and radio-frequency quadrupole. April 2021, full driver linear (linac) commissioned, accelerated energies above 200 MeV/nucleon by 324 superconducting radiofrequency (SRF) resonators operating at 2 K 4 liquid-helium cooling. preparation high-power...
The Facility for Rare Isotope Beams (FRIB) Project has entered the phase of beam commissioning starting from room-temperature front end and superconducting linac segment first 15 cryomodules. With newly commissioned helium refrigeration system supplying 4.5[Formula: see text]K liquid to quarter-wave resonators solenoids, FRIB accelerator team achieved sectional key performance parameters as designed ahead schedule accelerating heavy ion beams above 20[Formula: text]MeV/u energy. Thus,...
Abstract The Facility for Rare Isotope Beams (FRIB) began operation with 1 kW beam power scientific users in May 2022 upon completion of 8 years project construction. ramp-up to the ultimate 400 kW, planned over a 6-year period, will enable facility reach its full potential discovery isotope science and applications. In December 2023, record-high 10.4 uranium was delivered target. Technological developments accelerator improvements are being made entire key ramp-up. Major technological...
We present the first rf studies of medium-$\ensuremath{\beta}$ superconducting radio frequency (SRF) elliptical cavities designed for Michigan State University's Facility Rare Isotope Beams (FRIB) energy upgrade linac. The proposed this continuous-wave (CW) linac will double final beam from 200 to $400\text{ }\text{ }\mathrm{MeV}/\mathrm{u}$ heaviest uranium ions within 80 m space available in FRIB tunnel. Two prototype ${\ensuremath{\beta}}_{\mathrm{opt}}=0.65\text{ }644\text{...
Over the past years it became evident that quality factor of a superconducting cavity is not only determined by its surface preparation procedure, but also influenced way cooled down. Moreover, different data sets exist, some which indicate slow cooldown through critical temperature favorable while other states exact opposite. Even though there were speculations and models about role thermocurrents flux-pinning, difference in behavior remained mystery. In this paper we will present...

Construction of a new accelerator for nuclear physics research, the Facility Rare Isotope Beams (FRIB), is underway at Michigan State University (MSU). The FRIB linac will use superconducting resonators an operating temperature 2 K to accelerate ions 200 MeV per nucleon. requires 10⁶ quarter wave (80.5 MHz, β = 0.043 and 0.086) 248 half (322 0.29 0.54), all made from sheet Nb. Production being delivered MSU by cavity vendors. At MSU, are etched, rinsed, tested in MSU's certification test...
The Facility for Rare Isotope Beams (FRIB) superconducting (SC) driver linac is designed to accelerate all stable ions including uranium energies above 200 MeV/u primarily with 46 cryomodules containing 324 quarter-wave resonators (QWR) and half-wave (HWR) resonators.

Nitrogen-doping and furnace-baking are advanced high-Q0 recipes developed for 1.3 GHz TESLA-type cavities. These treatments will significantly benefit the linear accelerator community if they can be successfully adapted to different cavity styles frequencies. Strong frequency- geometry- dependence of these makes technology transfer amongst frequencies far from straightforward, requires rigorous study. Upcoming continuous-wave projects, such as proposed Michigan State University Facility Rare...
