ARIEL II Phase 2 – CANREB (CANadian Rare isotope facility with Electron Beam ion source)
November 14, 2013 IPR 2013 - ARIEL II: Phase 1 and 2 16
o High mass (A>30) RIB delivery requires the ISAC charge breeder (ECR) o Despite recent success (94Sr experiment) the ECR background (107 pps)
limits the purity and the deliverable RIB species (103 pps) o CANREB enables the delivery of high purity charge bred RIB from ISAC
(2017-2018)
