    Current Situation and Plans

    • Stack 'N Store through Owl Tue Apr 15.

    • Next week (from Apr 14), the plan is to have 3-5 shifts of accelerator studies on Tue and Wed (Apr 15-16).

    • Shot setups will be determined by stack size, usually >120 mA and by the Accelerator Operations status.

    • BEFORE the toroid and/or solenoid are ramped up, the Silicon detector should be completely powered down, both the high and low voltage. Make sure the SMT Shifter has turned the SMT detector off before asking the Ops Shifter to ramp up the magnets.

    • 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!

    Magnet Polarities

    (from Tuesday 08:00 April 8) 

       Solenoid = Reverse
   Toroid   = Reverse

    (from Tuesday 08:00 April 15) 

       Solenoid = Reverse
   Toroid   = Forward

    (from Tuesday 08:00 April 22) 

       Solenoid = Forward
   Toroid   = Forward

    (from Tuesday 08:00 April 29) 

       Solenoid = Forward
   Toroid   = Reverse

    Trigger Configurations

    global_CMT-11.03.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, 50E30 and 60E30. If help is needed with additional prescales, contact the Triggermeisters.
    • In this configuration, we see L1/L2/L3 rates of 500-1100/250-600/30-60 Hz, which is primarily a function of the instantaneous luminosity. If the rates are too high - L1>1200 or L2>700 - contact the Triggermeister. A good effort should be made to keep the average global FEB rate below 5%.

    The D0 Shift Schedule

    • D0 Shift Calendar
    • All Captain and DAQ shifts are 24/7.
    • Shifters can be on-call:
      1. if there is no Store,
      2. if MCR states there is no shot setup expected for 4 or more hours,
      3. if the situation with the sub-detector is stable,
      4. if there are no sub-detector tasks to perform (checklist, calibration, special runs, monitoring), and
      5. if the Shift Captain is in agreement
        6.
    • Calorimeter and Muon Shifters do not need confirmation from their sub-detector coordinators. However, there are Special Instructions which Muon Shifters must follow before leaving.
    • For the SMT & CFT/PS/FPS sub-detectors, the Shift Captain will need approval from their sub-detector coordinators (Eric/Breese or Fred respectively) before releasing the shifters:
    • Shifters must report in with the Shift Captain to give a contact number before leaving.

    Global Monitoring: Trigger & Physics Examines

    • Main Global Monitoring page.
    • Global Monitoring (GM) is being coordinated by Pushpa Bhat, Michiel Sanders and Joe Steele. 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.
