Medical isotopes from ISAC actinide targets

The ISAC facility (Isotope Separation and ACceleration) at TRIUMF provides a wide range of radioactiveisotope beams (RIB) for research in the fields of nuclear astrophysics, nuclear structure and material scienceby irradiating ISOL-type (Isotope Separation On-Line) targets with a 480 MeV proton beam from theTRIUMF H - cyclotron. We have developed a compact collection device for the implantation ofmass-separated RIB on a target disc at energies between 20-55 keV. We also have developed a method toretrieve >95% of activity from the implantation target by chemical etching and have investigated alpha recoilseparation of 213 Bi from a 225 Ac/ 225 Ra implantation source.
