SUMMARY:Speaker: Jim Strait (LBNL) - Title: CMB-S4: birth\, life and death of a major science project
DESCRIPTION:Research Progress Meeting \nDate: September 25\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jim Strait (LBNL) \nSlides: Download slides \nTitle: CMB-S4: birth\, life and death of a major science project \nAbstract: CMB-S4 was envisioned to be a comprehensive ground-based CMB experiment to make transformative discoveries and new insights in fundamental physics\, cosmology\, astrophysics\, and astronomy. It was conceived as a way to unite the entire CMB community to enable a ground-based experiment with capabilities beyond that of any of the smaller individual experiment to realize the enormous potential of CMB measurements for understanding the origin and evolution of the Universe\, from the highest energies at the dawn of time through the growth of structure to the present day. CMB-S4 was launched with great promise and enthusiasm at the 2013 Snowmass Summer Study\, grew into a large collaboration\, built a capable project organization\, developed an advanced technical design and scientific strategies\, was endorsed by multiple high-level advisory committees\, but ultimately was cancelled by the funding agencies in 2025. In this talk I will summarize the history and accomplishments of CMB-S4\, and provide an analysis of why it did not succeed. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
