Minutes: SBS Meeting Aug. 7, 2013
Attendees: 
Bogdan Wojtsekhowski, Robin Wines, Mark Jones, Douglas Higinbothum,
Carlos Gayoso, Charles Perdrisat, Alexandre Camsonne
(On phone:) Brian Quinn, Seamus Riordan, Nilanga Liyanage


1) Robin Wines gave an update on the magnet and showed floor layout

 a) see link for talk

 b) Floor layout shows both HRS at 125 degrees (minimum to allow SBS
 and Bigbite to fit).  Actually Right HRS must go to larger angle to
 clear truck door.

 c) May disconnect right HRS cryo lines (but not practical for GMn
 since right HRS needed for calibration.)

 d) SBS power supply (with heavy shielding) to be located (as show in
 slide 5) on beam left.  Left HRS will also act as shielding.

 e) Heavily shielded hut will also be needed for electronics, but
 closer to experiment.

 f) Hoses for SBS cooling LCW will allow for motion of SBS.  Power
 distribution may be flexible or have different sections of conductor
 used for different positions.

2) Bogdan discussed SBS annual review

 a) Review will be held in early November (possibly 4th and 5th).

 b) Will cover SBS and dependencies

 c) Expected talks include:
      Robin Wines - Engineering status
      John LeRose - Finance
      Nilanga Liyanage - GEMs
      Brian Quinn or Gregg Franklin - HCal
      possibly 3He target
      possibly ECal



3) Brian Quinn led discussion of new version of proposed SBS
   collaboration charter (version 3.11)

 a) Seamus points out that we should notify the Hall A collaboration
 coordinating committee chair (Julie Roche) that we wish to form a new 
 working group.

 b) Douglas suggests simplification of the procedure for modifying the
 charter (implemented in version 3.2)

 c) It is agreed that the charter will be discussed at the next SBS
 weekly meeting and, if there are no objections, will be considered
 adopted.  Brian is to publicize this in advance to give all
 interested parties the opportunity to attend.
