Running the DAQ

1. Navigate to the run directory cd run

2. Edit the DAQ configuration: Open daq.ini and set:

   • VME bridge address
   • TDC addresses
   • Number of triggers

3. Enable run mode: ensure the file runfile contains RUN

4. Start the DAQ:

    ../daq/bin/daq daq.ini N
   

   where N = run number (increment manually for each new run).

5. Stopping the run:

   • Automatic: The run stops when the configured number of triggers is reached.
   • Manual: Set the content of runfile to STOP.

6. Output: the data is saved in output_run_N.root.
