Description
The Facility for Rare Isotope Beams (FRIB) began user operations in May 2022 and has delivered more than 280 rare isotope beams to users, some of which were first-ever discoveries at FRIB. The facility features unique accelerator devices and capabilities, including: 1) the world’s largest heavy-ion superconducting (SC) linear accelerator, capable of accelerating uranium beam up to 200 MeV/u; 2) a large momentum acceptance fragment separator equipped with large-scale SC magnets; 3) a liquid lithium charge stripper. FRIB accelerator has been operating delivering more than 6000 hours of beam time annually, including approximately 4000 hours for rare isotope science and 2000 hours for industrial applications, with machine availability above 93%. In parallel with user operations, FRIB have been conducting the beam power ramp-up program. The maximum beam power achieved so far are 10.4 kW for uranium beams and 22 kW for lighter beams, with plans to upgrade beam intercepting devices, such as charge selector, target, and beam dump, to accommodate the ultimate 400 kW beam power. In this talk, the status of user operations will be presented with highlights of achievements in accelerator devices and beam acceleration. The plan for beam power ramp-up will also be discussed.
