Looking for WIMPs with the Cryogenic Dark Matter Search (CDMS) [abstract]

The Cryogenic Dark Matter Search (CDMS) seeks Weakly-Interacting Massive Particles (WIMPs), which are thought to comprise 80% of the matter in the universe. We look for rare collisions with nuclei in semiconductor detectors cooled to 40 mK. To establish the necessary low background the experiment operates deep underground, utilizes layers of active and passive shielding, and is designed to distinguish interactions by type and position.

Last December we released our analysis of the final data from the phase known as CDMS-II, which took place in the Soudan Underground Laboratory in northern Minnesota. We observed only 2 events with a WIMP-like signature and placed the strongest upper limit to date on the spin-independent WIMP-nucleon interaction cross-section for WIMP masses greater than 80 GeV/c2. In recent months much interest (and some controversy) has been raised by possible evidence of much lighter (~10 GeV/c2) WIMPs in other direct-detection experiments.

New analyses of data in-hand and upgrades for future phases of CDMS involving detector design modifications, greater target mass, and deeper sites are currently in the works.
