Abstract

New data are reported from the operation of a 4.0-kg ${\mathrm{CF}}_{3}\mathrm{I}$ bubble chamber in the 6800-foot-deep SNOLAB underground laboratory. The effectiveness of ultrasound analysis in discriminating alpha-decay background events from single nuclear recoils has been confirmed, with a lower...
