    • A complete list of toll-free international numbers can be found here.
  2. Enter the participant code: 3421244# (the # is needed when using the phone)


If there is a problem connecting via Google Hangouts/ReadyTalk, we'll use Skype as a backup. The relevant Skype user names are:


  • Rory Miskimen - rmiskimen
  • Elton Smith - eltonssmith
  • David Lawrence - aehsdad

some phone numbers if needed:

David: (757) 269-5567 (cell: 757-746-6697) Rory: (413) 545-2480

Minutes

Attendees: David L., Elton S., Bobby Smyth, Mahbub K., Tim W., Dave M., Mark D., Eugene C., Beni Z., Rory M.

  • Structural engineering of platform
    • 2m x 2m of steel (16.5 tons) (discs)
    • 10cm of space for cables on sides of MWPCs
    • Structure will extend through hole in plates on platform and distribute load to existing support structure
    • Dave M. asks if we need to adjust design to allow shimming in case beam hole needs to be repositioned
    • We will likely need to extend platform to allow racks to be moved back and still have clearance to rails
  • Hadronic LBL scattering
    • Rory showed a "roadmap" of contributions to LBL scattering contributions.
    • This was shown at the rare eta workshop at UMass last week
    • Pion polarizability is an important input to the LBL calculation
