In late 2007 NASA called for proposals to fund Astrophysics Strategic Mission Concept Studies. The goal was to generate concept studies for key future missions, which would be forwarded to the Astro2010 astrophysics decadal review committee for prioritization. Under the guidance and orchestration of the Primordial Polarization Program Definition Team, a NASA committee chartered to coordinate the activities of the cosmic microwave background (CMB) community, a CMB proposal aiming to represent the consensus of the entire community was submitted. A CMBPol Mission Concept Study grant was awarded in early 2008. Under the grant we reviewed the entire activities of the CMB community and proposed a path for the next decade. We also assessed the case and recommended a path for a future CMB polarization satellite.
The grant funded three community-wide workshops that were held over the summer of 2008. The goal of the first workshop, held at Fermilab, was to discuss the theoretical foundation of inflation and its signature on the CMB, as well as the theoretical aspects of other polarimetric signatures observable at millimeter wavelengths. Volume 1141 of the American Institute of Physics conference proceedings summarizes the results of this workshop. The second workshop, held at Annapolis, Maryland, centered on expected systematic effects in polarimetric experiments and their potential mitigation. The third workshop, held at the NIST facility at Boulder, Colorado, focused on the technology requirements necessary to make incisive CMB polarization measurements and what was needed to advance the technology to the readiness level required for a start of a space-borne mission. The electronic proceedings presented here are the result of this third workshop.
In preparing for the workshop the organizers assigned topical-editors for each technology topic. Each of them solicited white paper contributions from experts in their respective areas. The white papers were distributed to all participants prior to the workshop and were the basis for presentations and further discussions during the workshop. After the workshop the white papers were assembled to the summaries presented in these proceedings.
The papers give the current technology state-of-the-art with some projections for further development in the future. They all represent the immense technological progress in our field.
The prevailing opinion during the workshop was that from a technology aspect alone, the community is confident in its ability to begin a space mission in the next few years.
