How to run and display CR data acquisitions

(ver. JULY 2002)

When performing a CR data acquisition there are some operations that have to be done before starting the run, during the run and when run has stopped.  This page is a brief summary of all steps required to complete a CR acquisition. It is structured in a top-down fashion: each step is further explained in other sub-sections that you can reach quickly just clicking on the blue titles.

0. Preliminary operations

0.1    Check that slow control programs for straw tubes are running.
0.2    Check that HV, LV and gas flow for straw tubes are regular.
0.3    Check that HV, LV and gas flow for drift chambers are regular.
0.4    Check that HV for TOF are regular.
0.5    Check straw tubes discriminator thresholds
0.6    Launch the FINUDA Run Control program [FRC]
1. Starting the run
1.1    Fill the run form .
2. During  the run
2.1    Launch the monitor program (If not already done).
2.2    Reset the histograms for the new run.
2.3    Check that everything is going OK


3. When run has finished

3.1    Fill the logbook and the run form with the last informations (stop time, n. of events... )
3.2    Print the histograms.
3.3    Begin file transfer to the storage directory.


4. General

             4.1    How to change HV value in the finuda database.

0.6.  Launch The FINUDA Run Control program [FRC]

FINUDA run control program runs on fndrun machine. Once you  have opened a session as user frc to setup and start a DAQ run, follow the instruction you can find at the following link:

How to start FRC

1.1.  Fill the RUN  form

Whenever you start a new run you have to report the main run parameters (run number, start time, active detectors etc..) on a pre-printed form.  The form must be completed at the end of the run with the latest informations (n.of collected events, stop time,  etc..).  Any other information must be written on the logbook.
You can view and print the "RUN form" just clicking below:

2.2. How to reset the histograms


3.1. Fill the logbook and the run form with the latest informations (stop time, n. of events... )

3.2.  How to print the histograms


3.3. How to transfer data files to the storage directory

Now you have to remove the file from the original directory.
