Jul 26, 2011 Readout

Teleconference Time: 11:00 a.m. EST

• ESNET 8542553 and EVO session
• JLab Phone: in CC F326 is 757-269-6337 (usual room)
• JLab Phone in CC L207 is 757-269-7084
• Phone in the Regina Videoconference Suite is 306-585-4204
• Athens Phone: in Christina's office is 011-30-210-727-6947
• Phone:
  • +1-866-740-1260 : US and Canada

  • then use participant code: 3421244# (the # is needed when using the phone)
  • OR from www.readytalk.com type access code 3421244 into "join a meeting" without the # (you need java plugin)

Items for followup from previous meeting

1. Gap efficiency
   • Generate efficiency plots for nominal configuration before inclusion of readout elements DocDB-1789
     • Browsing the histograms:
       • a) check out code: svn co https://halldsvn.jlab.org/repos/trunk/home/zihlmann/photonstudy
       • b) goto src directory and type make (you need ROOT installed and ROOTSYS defined.)
       • c) go back up ../, and start program with ./src/scaner
     • current BCAL geometry implementation is not according to drawings.
   • Generate efficiency for typical reactions
   • Study effect of moving 4th plane upstream by 20 cm on tracking

Tentative Agenda

1. Announcements
2. Review of Action Items
3. Monitoring Update (Athens)
