Setting the TDC discriminators thresholds

Basic information

Vartan See Vartan's pages about the Discriminator Manager (DiMan)

Basic steps

The following information should be equivalent to Vartan's documentation (at least for our purposes):

On a CLON machine enter as clasrun.

Suppose to log in CLON04, type the following commands:

clon04>cd diman

A window will pop up.

 Select in the CLAS scheme the LAC detector clicking on it once;

  •  Click on the ACTION button:
    • select _conf --> channel discriminator

 A window will open. In this window you choose the threshold file   that you want to use
 Select a file

  • Click on the OK button after the selection
  •  Click on the ACTION button:
    • download --> channel discriminator, file values      
  • Click on the ACTION button: A window will open asking if you are sure or not to download the selected file
    •  read back -->channel discriminator, file values       

 In this way you monitor the discriminator threshold values that you have downloaded.


This part of the program does not work properly. To have a simpler but much more reliable test on the discriminators status use the program: caen_c207c croc17

  • Deselect LAC clicking on it once with the right mouse button
  • Click on the ACTION button:
    • exit    

Changing the threshold values in the file that you have downloaded:

  • Click on the EDIT button:
    • The EMACS editor window will pop up
    • Edit the file and put the correct threshold
    • Save the file
    • Close the EMACS window, otherwise you will not be able to use the GUI
    • Then proceed as before
