1-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
    Procedure
  • INPUT: slopes fitted to inclusive spectra :
    rebin(4)
    g[ch/GeV]= -760/slope, from fit of exponential to ADC-ped [40,100]
    for stripID > 270 & integral [40,100] <100 assume gain=30000 ch/GeV
    D E T A I L S
    Sector 5

    INPUT
  • SMD gains from slopes: gains05Usmd.dat , gains05Vsmd.dat
  • Pre/post-shower gains from MIP analysis using UxV method, Landau fit ( 'infinite' number of previous iterations) gains05PQR.dat
  • tower gains from MIP analysis using UxV method, Gaussian fit ( 'infinite' number of previous iterations) gains05tower.dat
  • pixels mask in DB as shown in Iteration 0 and from ascii file mask05.dat
    Manual corrections:
    * set gain to 30000 due to the low statistics: 05U281, 05U287, 05V282, 05V283 , 05V285, 05V287
    Sector 6

    INPUT
  • SMD gains from slopes: gains06Usmd.dat , gains06Vsmd.dat
  • Pre/post-shower gains from MIP analysis using UxV method, Landau fit ( intermediate iterations) gains06PQR.dat
  • tower gains from MIP analysis using UxV method, Gaussian fit ( crude SMD /PQR gains) gains06tower.dat
  • pixels mask in DB as shown in Iteration 0 and from ascii file mask06.dat
    Manual corrections:
    * set gain to 30000 due to the low statistics: 06U283-06U287 , 06V278 , 06V280 , 06V282 , 06V283 , 06V285-06V287
    Sector 7

    INPUT
  • SMD gains from slopes: gains07Usmd.dat , gains07Vsmd.dat
  • Pre/post-shower gains from MIP analysis using UxV method, Landau fit (intermediate iterations) gains07PQR.dat
  • tower gains from MIP analysis using UxV method, Gaussian fit ( intermediate iterations) gains07tower.dat
  • pixels mask in DB as shown in Iteration 0 and from ascii file mask07.dat
    Manual corrections:
    * 07U228 use ADC[40,80], to exclude peak from failed FEE
    * set gain to 30000 due to the low statistics: 07U281,07U285 , 07U287, 07V281 , 07V286
    * 07RC1- did not have gaun in Murad's file, 30K assumed
    Note, huge gain of 07TD08 - how did it happened?
    Sector 8

    INPUT
  • SMD gains from slopes: gains08Usmd.dat , gains08Vsmd.dat
  • Pre/post-shower gains from MIP analysis using UxV method, Landau fit (intermediate iterations) gains08PQR.dat
  • tower gains from MIP analysis using UxV method, Gaussian fit ( intermediate iteration) gains08tower.dat
  • pixels mask in DB as shown in Iteration 0 and from ascii file mask08.dat
    Manual corrections:
    * 08TC03 & 08TD03, 08PC03, 08RC03, 08PD03-08RD03- guessed gain, should be calc. from this iteration
    * set gain to 30000 due to the low statistics: 08U283 , 08U286 - 08U287 ,08V281 , 08V286 , 08V287
  • Plot below shows X vs. Y for UxV points.10K minB events from run 509027. Gains & maskes described above are used. The white line comes from the 5 blinde strips 06U033-37.
