Description

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.
