D0 Run Plan Period

• We have seen better muon system stability recently, even when running at L1/L2 rates of 10-20% above current guidelines. Until further notice, please use the following prescription for choosing prescales at run changes:
  • Prescale Set 30E30 - Initial Luminosity Range of 29-34E30
  • Prescale Set 25E30 - Initial Luminosity Range of 24-29E30
  • Prescale Set 20E30 - Initial Luminosity Range of 19-24E30
  • Prescale Set 15E30 - Initial Luminosity Range of 14-19E30
  • Prescale Set 10E30 - Initial Luminosity Range of 09-14E30
  • Prescale Set 05E30 - Initial Luminosity Range of 04-09E30
  • For luminosities less than 04E30, page the Triggermeister.
  In case of problems such as a very high PDT crash rate, just return to the standard guidelines.
• We will revisit this plan on Wed Jan 8 once we know the status of the trigger list version 10.0.
• Shot setups will be determined by stack size, preferably >140 mA and by the Accelerator Operations status.
  
  • Mon Jan 6 Eve - Wed Jan 8 Day: TeV studies
  • Wed Jan 8 Eve - 22:00 Sun Jan 12: Stack 'n Store
  • Mon Jan 13 Owl: Begin January Shutdown Schedule
  • Mon Jan 13 07:00-08:00: Lab-wide power outage.
• D0 shifts from Fri Jan 3 Day through Mon Jan 13 Owl:
  1. Captain and DAQ Shifts are 24/7.
  2. Detector and GM shifts are on-call starting from Mon Jan 6 Eve through Wed Jan 8 Owl. Every on-call shifter must report to the Shift Captain with contact phone number, and follow the standard on-call Shift Schedule Procedures, including filling out checklists and performing system checks.
  The shutdown shift schedule begins from the day shift on Mon Jan 13.
• 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.

• 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. If the rates are too high - L1>600 or L2>250 - contact the Triggermeister. A good effort should be made to keep the average global FEB rate below 2%.

• 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.

• 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.
