[Bteam] BTeam notes 2011-08-30

[Todd Satogata]

Hi BTeamers,

These are meeting notes from the Tue 30 Aug BTeam meeting. I'll write up
notes from the Thu 1 Sep BTeam meeting shortly along with a firmer
agenda for the Tue 6 Sep meeting. Comments, suggestions, and input are
always welcome. Thanks, and cheers!

                                                 -Todd

BTeam meeting notes, Tue 30 Aug
Attendees: Ryan Bodenstein, Joe Grames, Alicia Hofler, Michele Joyce,
     Geoff Kazimi, Geoff Krafft, Mike McCaughin, Noel Okay, Todd Satogata,
     Mike Tiefenback, Dennis Turner, Yan Wang

(*) Restarting BTeam meetings Tue/Thu 11:00 MCC to prepare for startup
     - Considerable input will come from 6MSD Ops/Recovery Review Wed 31 Aug.
     - CASA personnel are also assigned to certain startup tasks
       * Will include/track this list as one of many agenda items

(*) AHLA update
     - CED will be ready for HLA App review 19 Sep, then operations training
     - Can use CASA model support
       * C100/R100 install slots/locations (to Marie)
       * APELs: Hall deck configuration checks, particularly Hall A g2p (Yves)
         - Should include diagnostics locations (e.g. BPMs)
         - Can be used as a test of CED/model processes

(*) BBU Injector configuration
     - Todd's plan has 20 MeV injector energy, 177.78 MeV symmetric linacs
       * Beam currents up to BSY dump limit, 100 kW => ~130 uA
       * Tief raises question about potential BSY current limit in low energy.
         Todd will follow up.
     - Reza notes 22.5 MeV has been done 2-3 years ago
       * Reza: 20 MeV may be significantly harder
       * Tief: 2-pass only, rough beam quality can be rough, no parity quality.
         Believes that 20 MeV or even lower may be feasible.
     - Yan will develop a startup procedure and start circulating a draft
       for commentary and discussion at a future meeting. This will help
       identify other areas of concern for low energy injector operations.
     - There is a strong desire to take advantage of injector-only setup time
       to develop low energy injector configuration. This was also shown at
       the 6MSD recovery review on Wed 31 Aug.
     - Consensus: Set up 22.5 MeV injector first and put it in the bank, then
       work to set up 20 MeV with whatever time remains. Ilkyoung/Todd will have
       machine optics decks available for these two scenarios.

(*) Zigzag emittance tool
     - Intent is to provide faster, reproducible multiharp emittance measurements.
     - Dennis and Tief are continuing to work on this after Pavel's departure.
     - Still a development tool (e.g. model integration is at least partly by hand)
       * Determine in upcoming run whether this is worth investment to make
         a routine operational tool, including model integration.
     - Dennis and Todd (and Tief?) will meet Fri 2 Sep

(*) Next meetings 11:00 Thu 1 Sep (MCC) and 11:00 Tue 6 Sep (MCC)
