Abstract

Counting rates from the two 1-kg PNL/USC ultralow-background germanium detectors are ≤0.3 counts keV^-1 kg^-1 d^-1 between 6 and 9 keV and ∼ 2 counts keV^-1 kg^-1 d^-1 between 4 and 6 keV. These data show a significant short-time rate dependence due to blasting and other mining operations in the Homestake good mine. The mean shift in the centroid of the gallium x-ray peak was about 50 eV over a total period of about 500 days, indicating adequate stability for a search for annual modulation of Cold Dark Matter (CDM) particles.
