2-Iteration of SMD gains from pp200 minB data taken in 2004

  • events from the selected runs with TPC in the data were added together, runList
  • any minB triggered events are used (fast & slow), total 1.5M accepted eve
    INPUT
  • MIP peak position vs. strip ID (using gains from iteration 1) is approximated by :
    * universal curve for sectors 5,7,8

    * specific curves for sectors 6

  • The ratio of U-shape to the goal of 1.3 MeV is correction factor applaied to all SMD strips resulting with new gains

  • SMD gains Sector 5: gains05Usmd.dat , gains05Vsmd.dat
  • SMD gains Sector 6: gains06Usmd.dat , gains06Vsmd.dat
  • SMD gains Sector 7: gains07Usmd.dat , gains07Vsmd.dat
  • SMD gains Sector 8: gains08Usmd.dat , gains08Vsmd.dat

  • gains for towers/pre/post and all masks are unchanged (see iteration1)
