Title:     Progress towards new radioisotopes and higher RIB intensities at TRIUMF

Abstract: Over the past five years TRIUMF has operated routinely the ISAC facility at proton beam intensities up to 100 microA. A major departure from 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 materials with 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 microA only because of the material 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 75 microA. These developments are essential for the ARIEL (Advanced Rare IsotopE Laboratory) project for which TRIUMF just received funding. This funding includes the construction of a 500 kW, 50 MeV electron superconducting LINAC and a new target hall building capable of housing two new target stations.  One of these target stations is rated at 100 kW beam power from both, electrons and protons. The proton beam line utilizes a modified extraction port on the H- 520 MeV cyclotron. The other target station will be solely dedicated to the 500 kW electron beam for photo fission.
