Tracker Shifter CheckList

1) Temperature check (high priority)

  1. Check the temperature on this page (local POCC) or on this one (CERN Server)
  2. Select the working TTCE side (A or B) and the M-crate working side (A or B), according to JMDC.
  3. Check the following conditions:
  • The temperature of the Tracker (Sensor A and Sensor C) must be lower than 32C.
  • The temperature difference between the pump (Pt02_P) and the Accumulator-Set Point (Pt01_P) is alwasy more than 3C

Example of TTCE B-side and M-Crate B-side on, tracker temperatures <32C, DeltaT >3C between Set-point and Accumulator


  1. WARNING: if there are data but no web-interface temperature are not working check the AMI scanner:
    ssh ami@pcposk0 
    cd AMI
  2. If the scanning programs are setted on the wrong HK directory you must: ssh <Blocks_dir> <starting_block> 
    (the script kills the old scanners and starts new ones)

Example of TTCE B-side and M-Crate B-side on, tracker temperatures <32C, DeltaT >3C between Set-point and Accumulator


2) Check the Tracker Monitoring Tools Status

  1. Usual Tracker WorkStation is PCPOC08
  2. Login as user: tracker
  3. Go to directory
    cd TrackerUser/Monitor
  4. Check if the data processing daemons are running using the command
  5. Check that the directory used by the decoding daemon is the right one (ask DAQ shift for the active interface)
  6. If the directory is the right one you can kill the runnig daemons with the command: <\br>
  7. If the daemons are not running, you can launch them with the command:
    ./ <Blocks_dir> <starting_block> 
    (example: ./ /Data/BLOCKS/HRDL-A/ 0160/001)

3) Check Calibration

  1. Launch the Last Calibration Monitor with the command:
    MonitorUI Output/LastCalDB.root
  2. Compare the calibration with the reference one (see below)
  3. When a new calibration is available press the "Update" button to get the new data
  • Reference Calibration Summary:


4) Fast Data Quality Check

  1. Launch the block summary check:
  2. If the block is a not-empty data block (Blocks!=0) please check:
  • Low number of bad clusters
  • Approximate Track Reconstruction Efficiency ~ 50%
  • Average Tracker Event SIze > 300 words, < 5000 words (approx 1000 words in normal conditions, approx 2500 words for TAS runs)
  • Average Number of Hits per Track: ~ 6
  • Presence of TDR Boards Errors (the large amount of T018 errors is known)

5) Data Quality Check

  1. Launch the Last Run Monitor with the command:
    MonitorUI Output/LastRunHmon.root
