Minutes

Attendees: Arshak,Igal,Tim W.,Phil,Tim B.,Zisis,Liping,Jon Z.,Sasha,Josh,Susan,S.T.

• Procurement updates
  • The SICCAS crystals are at the lab but have not been inspected yet
    • Sasha trying to coordinate with management to allow him and Vlad B. onto the JLab site to do this
  • Light guide samples have arrived at JLab
  • Brass pieces not arrived at JLab yet -- maybe today?
  • first 20 mu-metal pieces shipped on Monday
• PAC jeopardy discussion
  • Consensus is that JEF physics is still solid and existing simulations are probably sufficient
    • We might consider extending physics reach to include π0e+e-, φ(scalar)π0 where φ(scalar)→π+π-
  • We did think that we should work on exclusion plots for the dark scalar. Igal will work on this.
  • Will be discussing jeopardy in meeting with GlueX folks later on Friday. Some unresolved issues:
    • What kind of documentation will we need to provide? Sasha will work on FCAL II construction table.
    • What is overlap of 2 approved GlueX proposals and what does this mean for JEF running time (expected to be in parallel with GlueX)? Management seems to want to merge the 2 running periods.
