[Bteam] BTeam Agenda: Tue 7 Feb 2012

[Todd Satogata]

BTeamers,

Here is the agenda for today's BTeam meeting, at 11:00 in the MCC meeting
room as usual. We have a full plate this week with m56 setup, C100 testing
(including operational considerations) and continued anticipation of the
5-pass spin-up later in the month. Thanks to Alex Bogacz for running a good
meeting last week -- we'll see you there this week. Cheers!

-Todd

    1 Optics on Call Report/Schedule

  * 31 Jan-07 Feb: Yuhong/Geoff
      o SL has still been running few degrees off crest to reduce Compton backgrounds
      o m56 ATLis developed, in place for Weds Feb 8 beam studies
  * 07 Feb-14 Feb: Balsa/Todd
      o TODO m56 Weds Feb 8 beam studies
      o TODO Readdress injection matching to NL, SL gang phase, Hall C Compton
      o TODO Restore SL MOMOD after SL on crest, confirm good Hall C Compton rates (Tief/ops)
      o TODO Diagnose intermittent problems in NL MOMOD (Musson? Tief? Plawski?)
  * 14 Feb-21 Feb: Fanglei/Mike Spata
      o TODO 5-pass spin-up schedule? Mid-February for Hall A, but early Feb for Hall B shift?
  * 21 Feb-28 Feb: Todd/Jay
  * 28 Feb-06 Mar: Rui/Tief
  * 06 Mar-13 Mar: Vasily/Yves
  * 13 Mar-20 Mar: Balsa/Alex
  * 20 Mar-27 Mar: Yuhong/Geoff
  * 27 Mar-03 Apr: Ed/Todd
  * 03 Apr-10 Apr: Fanglei/Mike


    2 C100 Status

  * Have been running well with 2L24 since Thu 26 Jan with few problems
  * Zone ESET is 75.04 MeV (GSET 13.4 for each cavity)
  * Possible interest in running 2L25 or both 2L24/25, increasing gradient?


    3 Manual linac RF cresting

  * QWeak cannot run while Krest is running
  * We should routinely manually touch up cresting
  * ~15 minutes by two experienced operators


    4 Beam Studies Report 1 Feb 2012 (Wednesday)
