SuperCDMS Begins Hunt for Dark Matter WIMPs in Canada

3/20/2026

Summary

Story summary

The Super Cryogenic Dark Matter Search (SuperCDMS) cooled its detectors to temperatures just above absolute zero at SNOLAB, Canada, enabling 24 silicon and germanium detectors to hunt for WIMPs.
WIMPs are believed to constitute about 85% of the universe's matter.
The underground site shields the experiment from cosmic rays, minimizing background noise.
Researchers are calibrating the detectors to optimize performance and explore unmeasured energy ranges that could reveal new physics.
