Abstract
The Gamma-Ray Infrastructure For Fundamental Investigations of Nuclei, GRIFFIN, is a new experimental facility for radioactive decay studies at the TRIUMF-ISAC laboratory. The performance of the 16 high-purity germanium (HPGe) clover detectors that will make up the GRIFFIN spectrometer is reported. The energy resolution, efficiency, timing resolution, crosstalk and preamplifier properties of each crystal were measured using a combination of analog and digital data acquisition techniques. The absolute efficiency and add-back factors are determined for the energy range of 80-3450Â keV. The detectors show excellent performance with an average over all 64 crystals of a FWHM energy resolution of 1.89(6)Â keV and relative efficiency with respect to a 3in.Ã3in. NaI detector of 41(1)% at 1.3Â MeV.
