Strip calibration

  • Introduction

  • From Orc:
    • Check that ORC is in INITIAL_STATE
    • Inform the pilot you will need to use IFR partitions
    • Put the IFR in LOCAL mode

  • Log on bbr-farm04 as babarifr
    1. Make a temporary directory
    2. Go inside the temporary directory
    3. Call the perl script $BFROOT/detector/ifr/bin/ifrCalib
    4. Open the xyplex windows: click on the Open Xyplexes button
      • Wait till you see 5 xyplex windows open
      • If one of the windows closes, click the Close Xyplexes button, wait untill all the windows are closed and then click Open Xyplexes again
    5. Dissolve the partition: click on the Dissolve Partition button
      • A small window will appear asking for confirmation
      • Click the Ok button
    6. Reboot the partition: click on the Reboot Partition button
      • A small window will appear asking for confirmation
      • Click the Ok button
      • Wait untill the string "Done executing startup script /dataflow/..." appear on all the last four xyplexes window
    7. Select the Analysis type: strips
    8. Click on the Run Custom IFR Calibration button
      • A window will be opened and some messages will apear
      • When the window will be closed, the main Epics pannel will not respond anymore
      • You have to wait ~5 minutes and a postscript file will be opened with the calibration results
    9. Check that the results are the expected ones and then exit form ghostview
    10. Close the xyplexes: click on the Close Xyplexes button
    11. Choose the Exit item from the File menu of the main Epics pannel
    12. Inform the pilot you don't need anymore the IFR partition
    13. You will have three files in the temporary directory: ifrcalib.xtc, ifrcalib.hbook,
    14. Use the tcsh script $BFROOT/detector/ifr/bin/moveIfrCalibFiles to automatically rename and move the three files
      • They will be zipped and moved in /nfs/bbr-nfs03/detector/ifr/calib/central/xtc, /nfs/bbr-nfs03/detector/ifr/calib/central/hbook, /nfs/bbr-nfs03/detector/ifr/calib/central/ps respectively
      • The name will be something like ifrcalib-custom-yyyy:mm:dd-hh:mm.format.gz
    15. Remove the temporary directory

  • ... If after having started the custom IFR calibration, it does not end
    1. Use the Emergency Stop button
      • The button shoul have appeared
      • If it has not appeared call the perl scriot $BFROOT/detector/ifr/bin/emergencyStop
    2. Click the Cleanup IPC button to kill pending jobs
    3. Dissolve and reboot the partition

  • How to compare two different IFR stand alone strip calibration
    1. Log on bbr-farm04 as babarifr
    2. Call $BFROOT/detector/ifr/bin/ifrCalibDiff
      • The syntax is ifrCalibDiff [firstFileName] [secondFileName]
      • If you omit the second file name the comparison will be done with the most recent strip calibration
      • If you omit both file names the comparison will be done between the last two most recent strip calibrations

  • Note
    • The kumac producing the .ps file is not updated and the labels on the histograms are not correct
    • Each page of the .ps file corresponds to a IFB
    • Each histogram corresponds to a minicrate connected to the IFB, the order is: the 1st histogram is the minicrate conncted up right, the 2nd one up left, 3rd one down right and 4th one down left
    • For any problems on the calibration setup contact the IFR DAQ experts
    • For any problems on $BFROOT/detector/ifr/bin/ifrCalibDiff script contact Riccardo Capra
