TRIUMF, Canada's National Laboratory for Particle and Nuclear Physics, Vancouver, Canada
Over the past five years TRIUMF has operated routinely the ISAC facility at proton beam intensity around and above 70 μA. Contrary to other ISOL facilities ISAC utilizes a modular assembly for the target station. This is mainly to provide enough radiation shielding for operation at high proton beam intensity. So far ISAC was licensed to operate target material Z < 82. Two actinide target (UO2) tests have been performed during the past two years to assess the ISAC systems (vacuum, nuclear ventilation, personnel safety) for actinide operation. The uranium oxide target is limited to 2 μA only because of the low operating temperature. We are now developing a uranium carbide target using similar techniques as for our other carbide targets (SiC, TiC, ZrC) operating up to 70 μA. Among the recent upgrade, the mass range, which was so far limited to mass lower than 30 has been increased to 150 with the installation of a charge state booster.
