Currently, the TRIUMF facility is upgraded with ARIEL (Advanced Rare IsotopE Laboratory), which will include a new EBIS (Electron Beam Ion Source) for charge breeding of rare isotopes. Heavy elements prepared into a high charge state are required to keep the mass-to-charge ratio A/Q low, which is essential for the two post-accelerators ISAC (Isotope Separator and ACcelerator) I and II. Because the isotopes of interest have short half-lives in the millisecond range and low production rates, the efficiency of the whole process of injection, charge breeding and extraction has to be very efficient. The repetition rate of 100 Hz requires fast high voltage control and switching. The goal is to achieve a charge breeding efficiency of at least 20 % to a single charge state. We describe the concept and development of the CANREB-EBIS which will be installed at ARIEL in the near future. Diagnostic techniques for the trapped ion species and preliminary simulation results for injection, charge breeding and extraction of the ions will be presented.
