The superCDMS experimental program

Abstract

The Super Cryogenic Dark Matter Search (SuperCDMS) experimental program is underway. The Soudan experiment is currently taking data with a 10 kg detector payload, and a generation 2 experiment at SNOLAB with a 200 kg payload has been proposed. First results from the SuperCDMS Soudan experiment are expected in 2013. The Soudan and SNOLAB experiments will reach a sensitivity to the WIMP-nucleon cross section of 5 × 10−45 cm2 and 8 × 10−47 cm2, respectively, for WIMP masses around 60 GeV/c2. Using new low-threshold techniques, both experiments are expected to achieve world-leading sensitivities to WIMP masses between 2 and 10 GeV/c2. In this paper we give an overview of the SuperCDMS experimental program and report on the discrimination capability of our new iZIP detectors.
