CMB-S4

After almost 37 years at Fermilab, Jim Strait will retire on July 7 to become Project Director of the Next Generation Cosmic Microwave Background Project, CMB-S4.  Strait will join the staff of Lawrence Berkeley National Laboratory (Berkeley Lab) to take on the project leadership role in CMB-S4, which is the largest collaborative undertaking yet to explore the relic light emitted by the infant universe. With 21 telescopes at the South Pole and in the Chilean Atacama desert surveying the sky…

Ground-based experiments designed to study the cosmic microwave background have gotten larger and more sophisticated over time. Now, nearly 200 scientists who have up until this point worked on different competing CMB experiments have joined forces to propose a fourth-generation experiment, the largest ground-based one yet, called CMB-S4.
