Ionization yield measurement in a germanium CDMSlite detector using photo-neutron sources

Two photo-neutron sources, ^{88}Y^{9}Be and ^{124}Sb^{9}Be, have been used to investigate the ionization yield of nuclear recoils in the CDMSlite germanium detectors by the SuperCDMS collaboration. This work evaluates the yield for nuclear recoil energies between 1 keV and 7 keV at a temperature of \sim 50 mK. We use... Show more
