[edit] Singles Scan Setup for a TIGRESS detector

Before commencing the singles scan, the detector needs to be mounted and the scanning table needs to be calibrated so that (0,0) is at the centre of the detector. Calibration instructions are here.

[edit] Procedures

  1. Using a browser, go to http://midtig03.triumf.ca:8081, and select tigscan
  2. In a terminal run mhttpd -p 8081 -D (runs daemon)
    Run mserver
    ssh lxdaq03 (password as usual)
    cd /home/tigscan/Collector
    ./fetigcol
  3. In a terminal tab,
    cd /home/tigscan/Packages, cd jacq_midas, cd V1.0,
    ./feMotor (Start motor)
  4. In a terminal tab,
    cd /home/tigscan/analyser
    Check if another analyser is running on tigaccept. Do this by typing odb, then selecting the tigaccept experiment, then typing scl. If you see an analyser, it may already be running on port 9090 ( the default). Exit this application. To check if you have the right port do ./analyzer -s 9090
    If it crashes, try ./analyzer -s 9091
    Whichever port works is the one that you will need for the roody step
  5. In a terminal tab,
    mlogger -e tigscan (turns on logger)
  6. In a terminal tab,
    roody.
    In roody, right click online, enter midtig03:(port number from 4)
  7. in ODB -->/Experiment/Run Parameters/Comment
    Add comment for the run
  8. In Roody -->right click and select draw for the following groups:
    Core
    Segment Blue+Green
    Segments Red+White
  9. In ODB-->/Equipment/Trigger/settings/master
    Global Multiplicity Mask= 0xFFE
    Disabled Port Mask= 0xFC3F
    Required Port Mask= 0x0
    /GE
    Hit Threshold =1250
    Trigger Threshold= 1250
  10. In ODB-->/Equipment/Trigger/common
    Event Limit=1500
  11. In Roody, for each window--> right click--> X-axis range--> (1-3000)
  12. In case spikes occur @ 170-180 keV,
    1. ODB--> Programs-->Stop fetigcol
    2. in terminal in part 2. run ./fetigcol
    3. check spectra again
  13. For a save directory:in ODB-->/Logger/Data Dir= “/data1/tigscan/det13/singles+date”
  14. TO START
    in ODB--> /Equipment/motors/settings/XY grid
    Start Position [0],[1]=-58; Incriment [0],[1]= 2; steps [0],[1] =58;
    Run at acquire=y; Start=y.
