Attendance: Shaul, Charles, Julian, Lloyd, Amy, Dave

Notes by: Karl

• May Workshop (all); Program google sheet
  • Conference, workshop, collaboration meeting;
  • The STDT Example
  • S4 Decadal Prep: Update from Michigan; does that affect the workshop (Lloyd? , Julian?)
• TeamX Sessions: next two weeks
  • TeamX reports to SOMA (Shaul)

May workshop

• conference / not conference. NASA requires 3 months forcasting for a 'conference'. Issues for Brendon, Roger, maybe others.
  • LUVOIR meetings are similar and not conferences. Main difference was all LUVOIR meetings were under same webpage as their telecons, so avoided the issue.
  • Now linked our workshop through wikipage. Plan to remove main workshop page and put everything under wiki.
    • Talked to Rita S. at headquarters and looks reasonable to get this changed. Filling out a form through Rita and she'll pass this to final determiners at headquarters.
  • CL: NASA is sometimes opaque. But framing this as 'working meeting' makes sense. Possible pushback due to number of attendees.
• Connecting to broader community. For decadal, astro connection is important. Also galactic science connections and neutrino science connections.
  • Worth attending other meetings and talking about PICO (e.g. for galactic science meetings)
  • Lloyd: go find them and talk, rather than setting up a special session (like at AAS) and expecting them to come to us.
  • SH: should we have a main conference contact? To field suggestions of conferences
    • LK: Can do this. Look at emails of options and forward them to appropriate speaker options.
    • SH: will also talk to Nick about what connections he knows, especially with S4.
  • SH: note that after Jan. we'll have little money to fund travel. Most money for travel will be now to December.
• Program finalizing:
  • status of Tracy and fundamental physics talk?
  • Lloyd/Dan to finalize with Tracy and finalize Cosmic Birefringence
  • Galactic/Extrgalactic
    • Nick with final panel invited will check with him
    • Sky models will be covered by Brendan or Clem
  • Tech panel being set by Shaul
  • Thursday morning:
    • Suzanne is a yes. Lloyd moderating. Shaul/LLoyd to finalize panel today.
    • Shaul to reach out to Scott D.
    • Intro talk about process?
      • Suggestions for person? John C.? –Shaul contact him. He served on previous panel.
        • Josh Frieman was on last panel also.
        • Mike Turner
        • S4 process was talked about by John C.

Decadal Survey timeline, from John C’s S4 presentation

• Fall 2018: Survey Chair selected (could be much sooner)
• Early 2019: Survey Committee finalized and approved
• Early 2019: 1st survey meeting, scope and date set for white papers
• Mar 2019: Short “white papers” due: - We need to submit CMB-S4 Overview white paper, i.e., killer science case, readiness, w/ cost estimate and schedule - We also want to encourage submission of additional science white papers that support CMB-S4
• Spring 2019: Survey requests additional input from selected projects - We need to have detailed CMB-S4 science and project description ready, what we are referring to as the “Decadal Survey Conceptual Design Report”

TeamX next 2 weeks.

• Instrument next week (3 days)
• Mission week after
• Input from TeamX to independent cost estimator (ICE)
  • Reservations taken to NASA.
  • Plan is TeamX to ICE (with TeamX having been briefed that goals of this TeamX is slightly different)
  • We can also add narrative to these slides.
    • 'rebuttal' was word used. but just explanation and added information is more Shaul's thought.
• Hoping to iterate with TeamX and their slides to send correct message to ICE.
  • AT: this is a reasonable expectation. Matches my conversations with TeamX. Have talked to TeamX folks about different audience for slides this time around.
