2024 Summer Collaboration Meeting

31 Jul 2024, 06:00 → 2 Aug 2024, 17:00 America/Chicago

Main Auditorium (National Center for Supercomputing Applications (NCSA))

Felipe Menanteau (University of Illinois at Urbana-Champaign), Jeff McMahon (University of Chicago; FNAL), Colin Bischoff (University of Cincinnati), Lindsey Bleem (Argonne National Laboratory & KICP)

The CMB-S4 2024 Summer Collaboration Meeting will focus on the path forward for CMB-S4 in light of NSF's decision to decline entry into the Major Facilities Design Stage, at this time, and the need to focus a Chile-only configuration. 

We will also address the work needed to complete the second edition of the Science Book. 

The goals for this meeting include:

• Collect and discuss information related to two main themes
  • Get status updates from ongoing and well-established planned experiments
  • Discuss the status and plans for the development of the all Chile option:
    Instrument configuration, scan strategy, capabilities, risk management, etc.
• Discuss the implications of the all Chile configuration on all science cases and consider the optimization of all science goals. 
• Continue to make progress on the Science Book Second Edition.
• Discuss and process the new path forward.
