Colleagues,

Following is the agenda and minutes from last time. We meet Wednesday
after the scheduling meeting.

Thanks,
Mike

BTeam Meeting Notes

* 7.5 weeks remaining before 6-month SAD (pending firm budget)
  We have ~1mo of carryover in the event of a government shutdown.
  There will probably be a slew of people burning vacation over
  the summer.
* 2011-03-30 Wed 14:00 BTeam Meeting Agenda
** Call for Strategic Priorities for BTeam
   Todd is soliciting input on priorities for studies before the 6
   month SAD, emphasizing strategy rather than tactics. Items
   currently on the list include:
*** Support of current experiments
*** CEBAF baseline
*** Additional bunchlength measurement, optimization
*** ORFP/Troubleshooting Guide Update
*** Pathlength Correction with MO
*** LOCO/RayTrace data, improvements
*** Optics machine/model improvements
*** Mott polarimeter precision
** Optics-on-Call Report: Byung/Yves => Shahid/Geoff
** Beam Studies Report
*** Outstanding ToDo items from previous beam studies
**** TODO Review/establish planned 12 GeV optics match procedures in
     spreaders/recombiners.
**** TODO CASA review (Yves? Tief?) of Arc1/Arc2 data from
[[https://cebaf.jlab.org/elog/elog_item.php?elog_id=1572645][e1572645]].
Done again Mar 11.
**** TODO Discuss impact of inj fopt correctors, cost/benefit of replacement
     Jay to work with Ron on developing the AtLis for making this change
during the summer.
**** TODO Revisit [[http://cebaf.jlab.org/atlis/task/8346][ATLis 8346]],
PZT if parity quality deems this necessary

** Beam Studies Planning
*** Continue 70 MHz MO Test Plan
[[http://opsweb.acc.jlab.org/CSUEApps/atlis/task/10814][AtLis 10814]]
(Curt and Tomasz)
*** Measure 6T Kicker response vs. frequency
[[http://opsweb.acc.jlab.org/CSUEApps/atlis/tasks/11002][ATLis 11002]]
(Mike Spata)
*** Setup Inejctor for High Current (Yan and Jay)
*** Measuring 0L03/0L04 and capture/quarter transport: Yves
     [[http://cebaf.jlab.org/atlis/task/9621][ATLis 9621]] and
[[http://cebaf.jlab.org/atlis/task/9622][ATLis 9622]]. What is Yves's
availability? How high is the
     priority for Hall C, checks of parity quality?
*** LOCO/Ray-Trace optics tests: Yves, Ryan, Tief
     [[http://cebaf.jlab.org/atlis/task/10708][ATLis 10708]]: Continued
optics evaluation of machine, particularly Arc3.
    Maybe testing next Tuesday.
*** Low-current BPM test: John Musson
     [[http://cebaf.jlab.org/atlis/task/10890][ATLis 10890]]: Check
dynamic range of BCM/BPMs from 50-200 nA with
     good accuracy at Qweak helicity flip rate for g2p, Hall A.

** APEL Hall Liason Comments
*** Hall A: Yves
*** Hall B: Tief
*** Hall C: Jay

** AOB?
*** TODO Injector configuration documentation: Reza
     Document proper operational injector configuration (6.3 MeV energy,
     crested within 5 degrees, etc): Reza et al (PAC paper in progress!)

* 2011-03-23 Wed 14:00 BTeam Meeting Minutes
** Todd away editing PAC'11: Mar 21-Apr 3
   Mike Spata will be acting BTeam lead for the next two weeks. Thanks,
Mike!!

** Optics-on-Call Report: Balsa/Alex (Alicia over weekend) => Byung/Yves
   A quiet week with no call-ins.
** Beam Studies Report
*** Coupling and Position Difference Optimization in 0L03-0L04
    [[https://cebaf.jlab.org/atlis/task/10984][ATLis 10984]] Yves/Jay
[[http://opweb/CSUEApps/elog/entry/1576069?PHPSESSID=c602a79f57c71d3653bb8629b8f243c1][minimized]]
the coupling across the 0L03/0L04 cryomodules
    [[http://opweb.acc.jlab.org/CSUEApps/elog/entry/1576069][Measured]]
coupling across cryomodules at 110%, 100% and 90% of nominal
    correction. Jay changed the scaling factor in lemi to be 90% of the
    initial scaling found in Zheng-hai's thesis.
*** Emittance Measurement at 130 keV
    Reza and Ken Surles-Law made an emittance
[[http://opweb/CSUEApps/elog/entry/1575944?PHPSESSID=c602a79f57c71d3653bb8629b8f243c1][measurement]]

    Jay to coordinate with Yan/Ops support
*** Mike Spata test?
*** Measuring 0L03/0L04 and capture/quarter transport: Yves

*** PZT Booster resurrection: Arne et al
     [[http://cebaf.jlab.org/atlis/task/10864][ATLis 10864]]: Need Arne,
Jay, Yves, or Riad present for testing assuming
     that there are still Hall C beam quality/pqrity quality issues.
