[Bteam] Today's agenda slightly revised

[Arne Freyberger]

  B-team Meeting


    1 2009-12-09 Wed 14:00 Agenda ATTACH


      1.1 Brief Hall Beam Quality Status

Let's keep this short this time?


      1.2 Hall-B g9-frost Pasyuk

    * Beam Requirements
    * Commissioning plans
      5 days of commissioning (concurrent with PREX commissioning) are
      on the schedule.


      1.3 PREX Requirements

Quick review of the PREX requirements which can be found at: 
http://hallaweb.jlab.org/parity/prex/PREX_Beam_Requirements.pdf 
<#[[http://hallaweb.jlab.org/parity/prex/PREX_Beam_Requirements.pdf>]] 
Please read the "Special Considerations" section carefully. We will need 
to develop a plan as to how Accelerator is going to address these 
requirements and considerations.


      1.4 Spring2010 run: Injection Chicane configuration Arne

Should we return to running with some M_56 component in the injection 
chicane? Would this hide our sins? Make us less immune to injector 
bunching issues? What other implications should be considered?


      1.5 Viewer limited BPMs Tief


      1.6 Large Synchronous Data (LSD) Effort Michele Arne

An effort to come to terms with the expected large data volume of the 12 
GeV era epics system has been started. The RF systems, DDA, BLA systems 
will have a large number of waveforms available for analysis. A small 
team has been formed to develop requirements and analysis frameworks for 
the data.

At present we are also thinking of adding a global event system 
<http://www.aps.anl.gov/epics/meetings/2006-06/Timing_Systems/Micro_Research_Timing_Components.ppt>. 
So that the epics records can be synchronized.

The team will need help from Bteam on this project. For example:

   1. How well should the data be synchronized?
   2. Any thoughts on analysis frameworks? Root? R? ScientificPython?
   3. Any thoughts on data structure? Root Trees? netCDF?


      1.7 Next Week

    * Hall-B Dark matter experiment Stepanyan
      Stepan will introduce us to a proposal for a dark matter search in
      Hall-B that will likely need some optics support.


    2 2009-12-02 Wed 14:00 Agenda--Notes

No realtime notes. Lengthy discussion on Hall-B beam quality at 
one-pass. Hall-B did not receive any good beam during the 
1-pass/transverse setup. Hall-B will have to schedule an additional time 
at one-pass.


      2.1 Machine Status summary

    * Hall-A issues?
    * Hall-B issues?
    * OPS issues Yan
    * Optics-on-Call summary Hofler


      2.2 Report from Hall-A collaboration meeting Benesch

Jay will summarize the recent Hall-A collaboration meeting. Issues 
raised include:

    * ep system removal
    * transverse target chicane
    * 11 GeV Moller experiment

2009-12-07 Mon 10:53
Did not get to the remain agenda.


      2.3 Review. Remaining 6 GeV program

We will go through the remaining 6 GeV program to see. Highlight 
"unknowns" and assign people to make the "unknowns" "knowns".

    * Hall-A
    * Hall-B
    * Hall-C
          o Nothing but Qweak, but do we really know what they want?


      2.4 Next Week

    * report from Hall-B on the g9-frost requirements
    * Viewer mode shift for BPMs (Tief)
