Canada’s national particle accelerator Centre TRIUMF is currently upgrading its facilities with the Advanced Rare IsotopE Laboratory (ARIEL) to deliver two additional rare isotope beams simultaneously to TRIUMF’s user end stations. A new electron beam ion source (EBIS) is included in the ARIEL facility to boost the charge states of the short-lived rare isotopes to charge-to-mass ratios of 4 < A/q < 6. For rare isotopes with half-lives down to 65 milliseconds and low abundancies of down to 106 per bunch, the whole process of injection, charge breeding and extraction has to be as efficient as possible. Furthermore the bunch repetition rates of around 100 Hz need a highly optimized setup. We present first injection-extraction measurements within the commissioning phase including characteristics of the electron gun with electron beam currents up to 1 A.
