NSCL Lecture Hall

The TRIUMF Isotope Separator and Accelerator (ISAC) facility produces intense radioactive ion beams using the ISOL method driven by spallation of various targets with 500MeV protons up to 100 microamps in current. The radioactive beams are delivered to various experimental stations for experiments at energies ranging from a few tens of keV to 15 MeV per nucleon. The Gamma-Ray Spectroscopy at ISAC group operates two HPGe arrays for complimentary studies of nuclear structure using both beta-decay and nuclear reactions of exotic beams. Recent decay studies with the 8pi spectrometer have focused on nuclei produced from Actinide targets in the neutron-rich mass 100 region around Sr and Zr. With accelerated beams delivered to the TIGRESS array recent studies include the d(94Sr,95Sr)p transfer reaction as well as various studies of halo structures in Be isotopes. Our group is also collaborating with several groups from universities across Canada on the GRIFFIN project to upgrade the decay spectroscopy capabilities at ISAC by replacing the HPGe aspect of the 8pi with an array of 16 large-volume clover detectors and instrument it with a state-of-the-art digital electronics data acquisition system. GRIFFIN will be completed in 2015 and will greatly enhance the capabilities in the nuclear structure and fundamental symmetries research programs with stopped radioactive beams. Recent experimental results will be presented along with an overview of the GRIFFIN project.
