2 this study? o enhance the priority of inflation science within the funding agencies. There is an opportunity to do this because the 2010 NRC Decadal Surve of Astrophysics will begin its wor in the Fall 2008 and accept input from communities through early 2009.

3 e Astrophysics Division of the ssion Concept Studie cience Mission Directorate olicits concept studies for trategic space flight science issions that may be carried out n the next decade or for which echnology development funding is ought in the next decade. e goal of the mission concept tudies is to develop high-quality cientific, technical, and cost nformation to be used for future

4 Decadal Surveys 1990 Bahcall 2000 McKee-Tayl he surveys take an overview of the state of astrophysics and make a prioritized list of recommendations for the upcoming decade.

Much will be learned in the next 5 7 years from Planck and suborbital experiments and the research they inspire. study is being developed. the most general level:

Does the plan promote a space mission now or one following 5 years of further results from

16 Input from the community * -Wide request for participation. -Three workshops open to everyone o four central topics: Theory, Foregrounds, Systematics and Technology. -Workshop summaries with an overvie which will be public and have an opportunity for input from people who are not part of the workshops. This is not just the US CMB community --

19 Workshop on Systematics in 2 weeks. - Organized by Gary Hinshaw and John Ruhl - Experience from experiments with data - Plans for experiments in development and future - Experiment simulation and analysis -Workshop on Technology in late August - Organized by Shaul Hanany and Kent Irwin - Detection techniques - Optical coupling - Bands and filters - Readouts

20 Input from the community (continued -A group of participants will write summary of each of the topics in th workshops. -These will be summarized by the workshop organizers into a proceedings. -The workshop proceedings along with presentation slides will be on the CMBpol website. -They will provide the basis for the report to the decadal.

21 sections of the report based on the workshop proceedings. -Drafts of the report will be on the CMBPol website for comment. -In November, the report will be sent to reviewers, outside the CMB field. -Starting in late December, the writing group will generate the final report based on the reviewer comments. A final workshop in Chicago which
