Current Situation and Plans

  • In general, The MCR schedule foresees stack and store as soon as the tune-up from last week's repairs is complete (expect Wednesday December 17th).
  • We are back to collecting quality data with the full detector in readout. Commissioning activities should occur between stores, unless approved by the run coordinator. Between stores, collect zero-bias data with as much of the detector as possible.
  • Track phi distributions (e.g. in VertexExamine) may show a dip around phi of 4.5. This is caused by a known CFT readout problem.

  • Shot setups are determined by stack size. At the present time, stack sizes are still smaller than before the shutdown, 80-100mA.
  • The Shift Captain should follow the MCR e-log and call MCR as needed to keep up with dynamic schedule of the Tevatron. MCR may give D0 quiet time or a Controlled Access. Page Dmitri Denisov for Controlled Access approval. See the whiteboard for Controlled Access requests.
  • Read the D0 Logbook before your shift in order to be better prepared!

Trigger Configuration

The default global trigger list is global_CMT-12.32.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:

   02E30, 05E30, 08E30, 10E30, 13E30, 17E30, 20E30, 25E30,
   30E30, 35E30, 40E30, 45E30, 50E30, 60E30, 70E30, 80E30, and scraping.
If help is needed with additional prescales, contact the Triggermeisters.

In this configuration, we see L1/L2/L3 accept rates of 600-1500/300-800/30-60 Hz, depending on the instantaneous luminosity and prescale set. If the rates are too high - L1>1500 or L2>850 or L3>65 Hz - or the global FEB exceeds 10%: contact the Triggermeister. A good effort should be made to keep the average global FEB rate below 6%.

Recorded Physics Run Limit:    4 hours     or    instantaneous rate in Taker < 25 Hz

The DØ Shift Schedule (D0 Shift Calendar)

All Captain, DAQ and SMT shifts are 24/7.

Other 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

Calorimeter, Muon and CFT Shifters do not need confirmation from their sub-detector coordinators. However, there are Special Instructions for Muon Shifters and Special Instructions for CFT/CPS/FPS Shifters which must be followed before leaving.

Shifters must report in with the Shift Captain to give a contact number before leaving.

Global Monitoring: Trigger & Physics Examines

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 is running the vertex examine (currently on d0ol27). Michiel Sanders has documented the Vertex Examine Instructions (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_4L1L2L3MP-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, and a low rate L3 mark and pass trigger that writes to the monitor stream. The prescales should only be changed by or with approval of the triggermeisters.

If there is a request for cosmic ray data: the default cosmics trigger list is official/special/cosmics-3.00.xml. If the CTT is available, official/special/cosmics_trk-1.00.xml can also be used.
