  • Phone connection only upon request.
    • +1-866-740-1260 : US and Canada
    • +1-303-248-0285 : International
    • then use participant code: 3421244# (the # is needed when using the phone)
    • OR from www.readytalk.com type access code 3421244 into "join a meeting" without the # (you need java plugin)

Participant Direct Lines

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

Items for followup from previous meeting

  1. Beamtest
    • Investigate if Hall B chiller is available for our use (Elton) Chiller will be used for the HPS beamtest.
    • Draft a run plan (Elton and Zisis)
    • Consider optimum configuration for 40 Bcal LED boards on mini-Bcal (Zisis, Elton, Christina): centre two columns on each side
