The Run Plan Standard Instructions can be found at http://www-d0.fnal.gov/runcoor/runplans/runplan_standard.html

The Current Daily Plan can be found at http://www-d0.fnal.gov/runcoor/runplans/runplan.html

There are new standing instructions for Captains. These involve making sure the Silicon Radiation Monitoring is running, making SAM dataset definitions at the end of a shift and recording the quality of data taken with colliding beam for all subsystems. Also check the Luminosity HV and Monitoring pages for current information.

Detector and Other Specific Instructions

Luminosity counter phototubes are very sensitive to the presence of the solenoidal magnetic field. Whenever current in the solenoid is changed (turning solenoid ON, OFF or changing polarity) it is the responsibility of the Shift Captain to set the HV on the luminosity counters according to specific instructions outlined below by Gregor Geurkov. Note that the Luminosity HV stays ON at all times, even during beam studies, but the setting of the HV to lower or higher percentages depends on the solenoidal field being off or on.

Forward Muon

There are four folders of muon shifter's instructions in the control room with detailed "step-by-step" instructions on how to run the system, check lists, Examine "reference plots" as well as call lists. There are experts (both pixels and MDTs) who will be watching systems operation daily and to solve problems, if any. They carry forward muon system cell phone and pagers. They are Igor Vasilyev (x6435) for pixels and Basar Sabirov (x2989, (630) 399-2367 (cell), x3438 (home)) for MDTs.

Magnets

Contact the Operations Technicians in DAB to ramp the magnets. The solenoid takes about 20 minutes to discharge and the toriod about 10 minutes. The shift captain should check that these are interlocked after they are ramped down.

Plan for Magnet Operations from Dmitri Denisov 10-Aug-2001

1. The Shift Captain is responsible for providing D0 Ops Shifter with instructions on turning D0 magnets ON/OFF or changing polarities.
2. Any changes in magnet currents should occur when there is no store in the Tevatron. The Main Control Room should be notified by the Shift Captain at least 10 minutes before any changes in D0 magnet operating conditions.
3. The polarity of the magnets is to be changed every week. Changes are to be done before the first store that starts after 00:00 o'clock Monday, and will be done independent of the amount of data collected during previous week(s) or any other conditions.
4. Until the 2001 October shutdown the sequence of polarities changes is: (R - Reverse, F - Forward)

   Week of	08/05	08/12	08/19	08/26	09/02	09/09	09/16	09/23	09/30	10/7
   Solenoid	F	F	R	R	F	R	R	F	F	F
   Toroid	F	R	R	F	F	F	R	R	F	R

5. Special modes of operation for the magnets (no field for detector studies, etc.) will be described on a case by case basis in the daily run plan. As soon as such studies are over, we should return to the sequence outlined in step 4. above.
6. In order to reduce operating expenses, the solenoid and toroids should be powered OFF if it is known that collisions are not expected within the next 24 hours. They should be turned ON at least 1 hour before the expected shot setup.
7. During magnet current changes, follow the procedures outlined in the run plan for operating luminosity counters high voltage. No other detectors are known to be affected by magnetic field changes.

Standing Instructions and Shift Tasks

The Captain should make sure that the Silicon Radiation Monitoring is running. See the online instructions for details.
(http://www-d0.fnal.gov/~naeema/radmon/shift/procedure.htm)

At the end of a shift, Captains should follow Wyatt Merritt and Heidi Schellman's instructions on how to define a SAM dataset. The definition should define all the runs that are deemed good from the store that should be run through reco.

The default event display d0ve should be run at all times for colliding data
start_daq d0ve

The ROOT version global_monitor examine should be run as well on d0ol04 (Captain's console), as this feeds histograms to the web. See the Captain's guide for details. There have been problems running this examine, but it does work if the instructions are followed closely.

Run Examines and Event displays at all times. In particular:

COOR records the begin and end of runs along with the crate configurations. DAQ shifters must still enter the relevant information in the taker pop-up windows. For details, see the message from Alan Stone.

Captains should summarize the runs taken with colliding beam and indicate their quality:

  
 start  end  run#  trigger  #events  toroid/solenoid  crate list  data quality (good/bad/unknown)  Comments
                                      (off,for,rev)                   (CAL,CFT,CPS,MUO,SMT)

At the begin of stores, the store number should be entered into COOR via

setup d0online

store_begin number.

store_end

Note: If you need to make changes in trigger configurations, contact the Trigger Meisters (Elizabeth Gallas and Levan Babukhadia).
