SuperCDMS background design and prospects for direct detection of low mass dark matter

The Super Cryogenic Dark Matter Search (SuperCDMS) Collaboration is building a direct detection dark matter experiment at SNOLAB. This experiment will explore dark matter-nucleon interactions for particle masses as low as ~0.4 GeV/c^2, with an expected sensitivity reach of approximately 10^-43 cm^2 at 1 GeV/c^2 dark matter mass. The experimental design, solid-state cryogenic detectors, and detailed sensitivity reach of the experiment will be presented. Connections are drawn between the low-background design of SuperCDMS SNOLAB and other low-background experiments. Construction of SuperCDMS is underway at SNOLAB and recent detector R&D results from the SuperCDMS Collaboration are opening windows to search for dark photon and electron-recoil-based dark matter interactions.
