[Richard Witt <witt AT usna.edu>]

Present: Alexei, Jim, Flemming, Tommy, Yuri, and myself

== Hardware

— water leak was fixed

— monitored 3D sensor during polarity flip this week

— no motion of TPC observed, somewhat surprising

—  will continue to work with sensors to monitor any movement

— Jeff and Tonko working on DAQ

— some questions about magnet trips and magnet ramping procedure 

== Electronics

— did not see data in outer TPX

— was error in new data structures

— event builders did not find proper data structure to fill

— is now fixed in online but not propagated to offline yet, request submitted

— most cosmics data taken so far has tracks only in half of the TPC (about 5 million)

— due to problems with ToF

— Yuri will need to evaluate these for usability

== Software

— some questions about combined PID and dE/dx tuning relative to ToF

— some deviation from model

— different deviation for pions coming from lambdas vs. K0short

— trying to understand this difference

— for >1 GeV momentum

— Tommy delivered QA script to Gene

— waiting for response when Gene returns

== AOB

— nothing new this week

Best Regards,

  Richard
