  • Current Situation and Plans

    • Through Tue Jan 7 Owl, the Tevatron will follow a schedule of Stack 'n Store with the exception of four days of scheduled accelerator studies: Tue & Wed on Dec 10 & 11 and Dec 17 & 18. Shot setups will be determined by stack size, preferably >140 mA and by the Accelerator Operations status.
    • Only the DAQ Shifter should issue the manual SCL inits during global physics data taking:
      • To clear Muon Readout errors (PDT,MDT,etc.)
      • Before resuming a run after a Calorimeter ADC error
      • Before resuming a run after a CFT+PS download
      • To clear L1 CTT FEB (with approval from CFT shifter)
      • Before resuming a run after an SMT download
      All shifters should clearly communicate requests for Pauses and SCL inits with the DAQ Shifter, and vice versa!
    • The Shift Captain should call the MCR at the beginning of each shift and as needed to keep up with dynamic schedule of the Tevatron. The MCR may give D0 quiet time or a Controlled Access (CA). Page Dmitri Denisov for CA approval. See the whiteboard for CA requests.
    Read the D0 Logbook before your shift in order to be better prepared!

    Trigger Configurations

    global_CMT-9.31.xml
    • Rules for Changing Prescales - choose the prescale set which has a name closest to the Luminosity at the start of the run.
    • Available prescale sets for the above trigger are:  05E30, 10E30, 15E30, 20E30, 25E30, 30E30, 35E30, 40E30, 45E30 and 50E30. If help is needed with additional prescales, contact the Triggermeisters.
    • In this configuration, we see L1/L2/L3 rates of 250-600/100-250/25-50 Hz, which is primarily a function of the instantaneous luminosity. A good effort should be made to keep the average global FEB rate below 2%.

    The D0 Shift Schedule

    • D0 Shift Calendar
    • All Captain and DAQ shifts are 24/7.
    • There are Special Instructions for SMT Shifters.
    • Detector shifters can be on-call for an owl shift:
      1. if there is no Store
      2. if MCR states there is no shot setup scheduled between midnight and 08:00
      3. if there are no subsystem tasks to perform (calibration, special runs, monitoring)
      4. if the Shift Captain & subsystem coordinator(s) are in agreement
      Shifters must report in with the Shift Captain to give a contact number before leaving.
    • All other shifts during the week are ON.

    Recorded Physics Run Limit

    • 4 hours

    •     or
    • 500,000 events

    •     or
    • Inst. Rate
      in Taker < 25 Hz

    Global Monitoring: Trigger & Physics Examines

    • Main Global Monitoring page.
    • Global Monitoring (GM) is being coordinated by Pushpa Bhat. The GM console, d0ol33, is reserved for the GM shifter during scheduled shifts when there is beam. Useful information, numbers and plots should be inserted into the electronic logbook under the GM tab.
    • The name of an institution will be listed next to the GM shifter when the Global Monitoring shift is being run remotely. There is a GM Web Communicator GUI to be used by the Shift Captain, remote GM Shifter, and other shifters as needed. The interface is very simple; shifters communicate via typed text. The gui should be open by default on the Captain console. If not, the gui can be launched with the following command sequence: setup d0online; start_daq gmwebcom.
    • Online Data Monitoring - Current status of Online Monitoring and Examine instructions.
    • The Shift Captain should continue to run the vertex examine (currently on d0ol27). Michiel Sanders has documented the Vertex Examine Instructions in PDF and HTML. For reference, look at the VE plots entered in the logbook during previous shifts.

    Periods Without a Shot Setup or Colliding Beams

    • During non-colliding beam, the  zero_bias_3L1L2L3_1out-1.00.xml  trigger should be run with all available crates to exercise the DAQ as long as this does not conflict with commissioning or calibration efforts. By default, 'Recording' should be ON as we would like to monitor the full data path from the detectors to tape at the Feynman Computing Center. There are three trigger bits with prescales which have been tuned both to exercise the L1, L2 and L3 rates and to send an average of 1 Hz to tape. The prescales should only be changed by or with approval of the triggermeisters.
