Abstract
CMB-S4 is a planned ground-based experiment with scientific impacts reaching from transformative measurements of the cosmic microwave background (CMB) to a deep legacy millimeter-wavelength dataset covering a large fraction of the sky. To meet its ambitious goals, CMB-S4 plans to have small-aperture (0.55-meter) and large-aperture (6-meter) telescopes located both in the Atacama desert (to access a large fraction of are the sky) and at the South Pole (for targeted deep-field observations). A total of over 500,000 superconducting detectors will be distributed across these telescopes, enabling a necessary leap in sensitivity. In this talk, I will give an overview of CMB-S4. I will highlight some of its scientific opportunities as well as presenting the driving technical considerations and the current experimental design.
