Attending: Dave L., Itaru, Ashot, Raphael, Abdellah, Eric, Yar, Mark, Dustin, Sam, Anatoly, Rafael, Doug, Dave K., Valeri
On Phone: Liping

Announcements:
Liping: Discussion of UNCW/APS meeting. Conclusion: one section of two 30-minute invited talks and eight to twelve 15-minute contributed talks. Please send ideas and opinions to lgan@jlab.org.
We also have a collaboration meeting that weekend (November 5-6-7).

Dave L: We received two more HV mainframes and several boxes of modules - they’re in the test lab area now.

Ashot: Bogdon’t HV and racks issue not resolved.

Doug: Safety and space issues raised about test lab area. Space is becoming premium and turnaround to the warehouse is a matter of hours, so don’t be shy about moving stuff there - even for a few weeks. The area is high profile and safety is a high concern - nothing goes on top of cabinets, no flammables without an appropriate cabinet, police your trash, etc.

2 from A&T
2 from UNCW
2 from Uky (Aram on software + 1 other)
2 from UMass (Eric + 1 other)
