Wednesday, 19 November 2008
BNL, 50-I-189, at 15:00 (GMT), duration : 01:00

Conference Phone Number: 510 486 7333

   Time:  10 - 11 am EDT

 * --===================================--*

  Agenda:

    1)    FY09 Capital and R&D proposals to be submitted to ADBoard - Nu
    2)    Updated report from the Shifts Committee -        Olga
    3)    Review Committee for FHC - Nu
    4)    AoB
* --===================================--*

    Brief Summary:

   1) Attending: Helen, Olga, Jamie, Zhangbu, Nu, Bernd, Bill

   2) Shift Committee: action items (a) send the satistics to Council; (b) ask Council discuss how to respons to those institutes who did not fulfile their shift responsibles - -ask for explainations; reduce number of authors or sign up more shifts early in next run;

  3) CAD meeting (Bill/Jamie): Cool down on Feb. 2nd; No more access after Feb. 6th; Feb. 20: collisions for physics. STAR needs a list of priorities, starts the discussions in PWGc; for example, Spin: (i) first W+ cross section at mid-y; (ii) hadron-jet correlation; (iii) ALL

  4) Funding:send the existing both lists to ADBoard for discussions of the priorities

  5) Online tracking: group forming

    Notes:

    1) STAR Regional meeting at VECC: Nov. 24 - 25

    2) QM09 abstract deadline: Dec. 15th

    3) BES meeting: Dec. 17-18 at BNL: summarise goals and next steps in BES
