Tape Handling in the S117 DAQ System

• If you have a new tape you have to initialize it !

    Command:        init tape <label>
    The label is limited to 6 alphanumeric characters. It should be
    "A04xxx"
    where:
     "A" stands for the master tape ("B" would be the first copy of the tape)
     "04" is the fourth ALADiN experiment
     "xxx" is a running number beginning with the first tape
  

• Now you have to mount the tape

    Command: mount tape
  

• If you want to start a new run you have to open a new file

    Command:        open file size=120 /auto /pr
    you will be promptet for the following:
    Tape label [] :                 <- just <RETURN>
    File Name [] :                  <- just <RETURN>
    User Name [] :                  <- just <RETURN>
    Run ID [] :                     <- the current run-number; look in logbook
    Experiment [] :                 <- S117
    Date and Time [] :              <- just <RETURN>
    Enter Comment (exit with <RETURN>) :
    Comment :                       <- type in the beam, energy, target,
                                       trigger, and whats the weather like :-)
  

• If you want to stop a run close the current file

    Command:        close file
  

• If you want to remove the tape you have to dismount it

    Command:        dismount tape
  

  WRITE LOCK the tape immediately after you take it from the drive !
