Reaccelerating long-lived rare isotopes at FRIB
Year: 2025
Type: conference-paper
Abstract: The ReAccelerator at FRIB successfully ran its first stand-alone beam in May 2021. Several technical upgrades were implemented to expand its scientific capabilities, including a new BMIS source, a room-temperature rebuncher, and the ReA6 accelerator with its corresponding experimental vault. Following the successful commissioning of these upgrades, over 25 beams were delivered to experiments, including six long-lived rare isotopes: Be-7, Be-10, Al-26, Si-32, Ni-56, and As-73. However, isobaric contamination posed challenges for beam delivery, requiring various strategies to improve beam purity. In this contribution, we outline the key steps that led to the success of the stand-alone program, including a description of the upgrades, approaches and results to mitigating isobaric contamination, and planned future improvements.
