The first phase of the Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB experiment proposed is a 110 kg array of germanium and silicon athermal phonon detectors. It is expected to reach a better sensitivity by an order of magnitude than that which has been achieved so far by the best experiments in the field. The technical challenges of constructing a payload of this size have led to the development of 1.4 kg germanium detectors (100 mm diameter, 33 mm thick), which are 2.3 times larger than those presently in use in the SuperCDMS experiment at Soudan. The first results from testing of a prototype detector with interleaved phonon and ionization channels are presented. The test results are promising for the use of these detectors in the next phase of SuperCDMS.
