CMB-S4 Collaboration Bylaws (as ratified March 19, 2018)

CMB-S4 Interim Collaboration Coordination Committee (ICCC)
From now until approximately March, 2018, the Interim Collaboration Coordination Committee (ICCC) for CMB-S4 will coordinate the activities of the Working Groups formed to work on collaboration bylaws and technical and science efforts. The ICCC will work to facilitate cross-group communications, help coordinate schedules and milestones for the Working Groups, and prepare preliminary documents for ratification by the full S4 collaboration. The goal date for ratification is March, 2018. The ICCC will meet periodically with representatives from the DOE and NSF to keep them updated on progress and to receive their input and advice. The ICCC has 15 members (see link to list below); the co-chairs are John Carlstrom and Suzanne Staggs. If you have input or questions about the ICCC work, you may email the entire ICCC using s4-iccc_at_box.uchicago.edu, or individual members (included in the list linked below). The ICCC will disband once the governance bylaws are ratified and its successor has been established.

Useful files/documents for input to drafting CMB-S4 collaboration policies:
File:CMB-S4 Bylaws Example-v2.pdf -- Example of CMB-S4 Bylaws drafted by Karen Byrum prior to the Harvard workshop to give us an idea of what CMB-S4 Collaboration Bylaws may look like. The working groups should feel to use as much or as little of this draft as they wish. None of the statements or procedures in it should be considered as decided or even recommended. However, the text will hopefully provide a useful template.
The following files are from the collaboration sessions at the Harvard workshop -- linked again here for convenience.

Older (ICCC Voting)
As agreed upon at the Aug 2017 Workshop, the Interim Collaboration Coordination Committee (ICCC) for the S4 will coordinate the activities of the Working Groups formed to work on collaboration bylaws and technical and science efforts. The ICCC will have 15 members. S4 registered voters will choose 7 members, and the remaining members will be appointed by the S4 Workshops Science Organizing Committee to ensure diversity on the ICCC, including career experience, institutional sizes, projects, locations of institutions, etc. The ICCC will elect its own chair, and other positions as needed (like deputy chair and secretary). The ICCC will disband once the governance bylaws are ratified.

CMB-S4 Concept Definition Task Force
In December 2016 the NSF-NASA-DOE Astronomy and Astrophysics Advisory Committee (AAAC) established an Cosmic Microwave Background Stage 4 Concept Definition Task Force (CMB-S4 CDT) as a subcommittee to develop a concept for implementing a ground-based CMB-S4 experiment. (Link to NSF CDT site.)

CMB-S4 Science Book
The purpose of Science Book is to set the scientific goals for CMB-S4 and specify the measurements needed to achieve them, which will then be translated into the instrument requirements. This will set the stage for defining the instrument.
- The First Edition of CMB-S4 Science Book is posted on the arXiv and also available here: File:CMB-S4 ScienceBook 1stEdition arxiv version.pdf
The history of posted Science Book drafts can be found here: CMB-S4 Science Book Comments.
The Concept Definition Task Force has been tasked with writing down science requirements, with three suggested levels (sky's the limit, minimum worth doing, something in between). John C. has, in turn, asked the Science Book chapter leads to create a summary table of requirements from the book. A workbook / dialog for putting that table together is here: Putting Together the CMB-S4 Science Book Requirements Table.
CMB-S4 Instrument Technical Papers
Goal of CMB-S4 instrument technical papers are to summarize the current state of the technology and identify R\&D efforts necessary to advance it for possible use in CMB-S4. CMB-S4 will require a scale-up in number of elements, frequency coverage, and bandwidth relative to current instruments. Because it is searching for lower magnitude signals, it will also require stronger control of systematic uncertainties.
