• Updates
  • VMM3
    • root file to plot - issue with ROOT Makeclass with stl - will try to plot
    • Direct output LVDS serial for 12 channels : Ben will gather what is available tat could read the signals
    • X ray test : might be option with USTC board since we have contact there
  • MPD developements ongoing : Danning trying to test , test setup powered up
• more discussion VMM3 test with X-rays : Ed investigated option using ATLAS board made by USTC, JP mentionned we have USTC collaborators so loaning a board or having them do tests for us might be a viable option instead of designing a board ( a few more weeks to decide )
• discussion about data reduction with Weizhi
  • send all MPD data from VTP to computer : either way data will go through VTP
  • other option implement TCP stack on MPD but need Paolo Musico to look at it
    *Compton

• Hanjie : showed plots of run split in 4 separate parts - large variation of asymmetry
• broke runs in several parts, and laser on and off
• run with blocklevel 20
• Ben idea : large rate background events contaminates one helicity window, need to find a way to cut them out
