Workshop overview

The Princeton workshop continues a successful series of meetings bringing together the CMB experimental and theoretical community to plan a coordinated, stage-4 ground-based CMB experiment. The workshop is supported by Princeton University with a generous contribution from the Kavli Institute for Cosmological Physics.

This meeting will focus on moving us towards the Decadal Survey and project formation. Each day will have a different flavor:

  • Thursday - Collaboration, Project and Decadal Survey Report updates and discussion
  • Friday - Broader community building ahead of the Decadal Process
  • Saturday - Parallel Science & Technical Council sessions

Meeting Info & Registration

About This Wiki

As for previous workshops, we will use this wiki to organize the sessions, to capture the input from them, and to develop next steps. Participants are encouraged to edit the wiki directly, including uploading plots or a few slides.
