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.
