Present: Alexei, Flemming, Tommy, Gene, Yuri, Iouri, and myself

== Hardware
— continuing measurement
— now have right scale and additional magnification glasses
— have 1 oxygen sensor and 1 was ordered this week 

== Electronics
— Nothing new reported this week.

== Software
— looked into the sector 18 issue mentioned last week
— Gene was given a phi region, but there may be some misunderstanding 
— upon initial examination, signed DCA is a bit messy on east, but sector 18 doesn’t seem to be exceptional
— charged ratios show some acceptance effects due to dead regions in some sectors, but not sector 18
— sector 21 shows a strange split, maybe this is the sector that was noticed
— Continuing work on alignment
— looking at high voltages
— looks like different direction of electric field in different sides of TPC (perhaps due to sag?)
— Work by Iouri  Vassiliev on dE/dx in P23id
— Hyperon reconstruction at 3.5 GeV in P21id and P23ie
— Very nice results with newer calibration (P23ie)
— see link that will be posted to TPC list separately
== AOB
— Need to discuss list of topics for collaboration meeting
— Also need to decide on speaker for that talk
Best Regards,
  Richard
