CMB-S4 comprises a joint DOE/NSF project and a scientific collaboration.
The project is charged with the construction of the experiment and the delivery of science-quality single-frequency maps and transient alerts. The project office can be contacted here.
The collaboration is charged with providing the expertise to set the experiment’s scientific goals, to determine the measurement and technical requirements to meet these, and to extract the key science results from the single-frequency maps and alerts. The collaboration spokespeople can be contacted here.
Technical working groups, coordinated by the corresponding subsystem L2 lead, are joint project/collaboration activities for designing, developing, and deploying their subsystem deliverables.
Analysis working groups, coordinated by conveners appointed by the collaboration spokespeople, are collaboration activities for developing the analysis pipelines to derive the science results and deploying them to ensure that the experiment design meets the scientific requirements.
