Abstract

CANREB (CANadian Rare isotope facility with Electron Beam ion source) at TRIUMF will deliver pure, highly charged, radioactive ion beams suitable for acceleration in order to perform experiments to investigate nuclear reactions. Radioactive isotopes at TRIUMF are produced by bombarding solid targets with high energy particle beams. Singly charged ions are extracted from an ion source immediately coupled to the target. CANREB will complement the presently used ECRIS based charge state breeder system by providing higher purity beams and extending the available mass range. Ions are first sent through a high resolution mass separator, where most of the isobaric contaminants can be removed. After this, the ions are injected into an RFQ cooler buncher and finally bunches are injected into an EBIS for charge state breeding. The bunch repetition time is set to 10 ms. This will also allow operation with short lived isotopes. To guarantee the short breeding time for the entire mass range up to uranium and to have a high injection efficiency, the EBIS is designed to operate at an electron beam density of up to 20 000 A/cm2. With the EBIS being operated at ultra-high vacuum, and no plasma wall interactions, additional contaminants induced by the charge state breeding process are expected to be significantly reduced compared with the ECRIS. Total beam intensity is limited mainly by space charge in the buncher to about 107 ions per bunch.
