Attendance: Shaul,Amy, Brendan, Al, Roger, Bill
Notes by: Brendan

Agenda:

• Update on management of WG and mailing lists (Shaul)
  • UMN physics listserv is retiring, so future working group mailing lists will be done through Google Groups: Shaul has already done this for extragalactic, data challenge, and imager. Some bugs have been found. Shaul can set this up for other WGs if needed.
• Technology Working Group and Plan (McMahon)
  • Roger put together a review of relevant technologies: Slides here
  • Roger is technology person at JPL. Jeff and Roger plan to have offline discussion with different groups around the country - get them to augment what they have provided to S4 tech book with any material relevant to a space mission. Jeff following up with NIST, Berkeley, GSFC folks; Roger to check in with McGill, Brad Johnson, Charles Lawrence, Peter Day.
  • The Inflation Probe should address some specific questions quickly: e.g., what detector technology to use above 800GHz? Power dissipation? How to get a community consensus on these questions? Use S4 as a starting point, solicit input from teams working on these individual technologies, present this information again to the EC.
  • In the spirit of transparency, need an opportunity for some back-and-forth: perhaps a open review by telecon for Roger and Jeff to present their results and get feedback.
  • Keep in mind that this is a current snapshot showing we have a solid case fitting in the cost cap, not a formal technology selection - were this mission to fly 10-15 years from now it is likely to look very different technologically. But important to have some baseline technology selection.
• Update on NASA management of probes and expected deliverables (Shaul)
  • Deliverables1.1
  • Entire slide package is also available on the wiki.
  • Study report is ~50 pages.
  • Engineering Concept Definition Package: prepared by JPL. This is only submitted to the decadal panel on request. Primary use is for the Independent Cost Estimate.
  • Can we find out what tools/models will be used by SOMA (the independent cost estimators) ? Shaul will ask. JPL has a number of models that can be used to check variance.
  • Independent Cost Estimate does not include pre-phase A technology maturation costs, but we should be careful about including too many low maturity technologies to avoid large cost penalties.
• Imager WG Update (Shaul)
  • first draft baseline imager (optics/focal plane + justification) targeted for end of July
