Description

Astrophysical observations of large scale gravitation suggest an abundance of non-baryonic dark matter. The Super Cryogenic Dark Matter Search (SuperCDMS) is designed to detect weakly interacting massive particles, a hypothesized solution to the dark matter problem. The SuperCDMS technology is based on germanium detectors instrumented with a new interleaved ionization and athermal phonon sensor layout. The ability to measure phonons allows an alternative operational mode, the CDMS low ionization threshold search (CDMSlite), optimized for WIMP masses below ~10 GeV. In this talk we describe a 10-kg-day exposure taken in this mode with SuperCDMS detectors at sub-keV thresholds. We will present results and constraints on the scattering cross-section of low-mass WIMPs. The SuperCDMS Collaboration is designing a 200-kg experiment for SNOLAB. We will discuss the design and scientific capabilities of the proposed SuperCDMS-SNOLAB experiment.
