  • Phone connection only upon request.
    • +1-866-740-1260 : US+Canada
    • +1-303-248-0285 : International
    • then enter participant code: 3421244# (remember the "#").
    • or www.readytalk.com (and code without the #)

Participant Direct Lines

  • JLab Phone: in CC F326 is 757-269-6337 (usual room)
  • JLab Phone in CC L207 is 757-269-7084

Items for followup from previous meeting(s)

  1. Send table of light guide measurements for Elton and Tim to review for acceptability (Iñaki)
  2. Check on Fcal monitoring board review (Elton and Fernando) Fernando has reviewed the drawings and has approved them.
  3. Update plexiglass sheet drawings and send it to IU and Athens for comments (Elton and Tim) Sketches were found and pass on to IU (John Frye) to develop a design
