CMB-S4

CMB-S4 is the next-generation ground-based cosmic microwave background experiment.

With 12 telescopes at the South Pole and in the Chilean Atacama desert surveying the sky with 500,000 cryogenically-cooled superconducting detectors for 7-10 years, CMB-S4 will deliver transformative discoveries in fundamental physics, cosmology, astrophysics, and astronomy.

CMB-S4 will provide measurements of the CMB at unprecedented precision and permit fundamental new insights into a broad range of physics.  These measurements will enable the search for signatures of primordial gravitational waves, probe the nature of dark matter and dark energy, map the matter throughout the Universe, and capture transient phenomena in the microwave sky.
