  *pdf

  v1.0 Dec 17 2007, Pixel Detector Calibration

  • summarizes the calibration requirements for the pixel detector and describes the calibration strategy

• Code development: Pixel DAQ developers

• 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
