      • nice explanations on what are Threshold/TOT scan and tuning, timewalk, intime threshold, MonLeak and BOC scan
    • May 9 2008, Claudia Gemme, Plans/News in Commissiong
      • pp8 describes a request of immediate implementation of inlink, outlink/inlink, BOC tunning in Calibration Console
    • May 8 2008: Claudia Gemme, Threshold scans during sign-off in Pixel detector group meeting
      • graphical instructions showing how to do calibration analysis
    • May 8 2008: Lucia Masetti, Status and plans for DAQ/calibration in Pixel Commissioning
    • May 7 2008: Claudia Gemme, My 'personal' to do list from the sign-off experience

  • Documents
    *pdf
    v1.0 Dec 17 2007, Pixel Detector Calibration
    • summarizes the calibration requirements for the pixel detector and describes the calibration strategy

  • Analysis Type
    • Inlink
      • Send config and Read analog current
      • Summary histogram in log format with tags for the kind of measurement, tmiestamp and masks of enabled PP0, modules, and FEs from Inlink Scan
      • decode summary histogram and read back current values for the configured module
      • inlink OK: analog current greater than 130mA (per module)
    • Inlink/outlink
      • Preset BOC_LINKSCAN
      • Reading back data to/from the formatters
      • 2D histogram with outlink vs inlink map from Inlink-Outlink scan
      • decode 2D histogram and read back relative amount of data received on the expected outlinks
      • outlink OK: response greater than 30% (per module)
      • Goal:
        • show list of modules/PP0s failing each cut with measured value and expected inlink or inlink-outlink pair
        • correct DB
        • swap fibers
    • BOC tuning
    • Basic Bump Connectivity
      • look for lower noise pixel on the collected data
