Current Situation and Plans

Tue 26-Feb-2002 22:30
MCR plans have changed - there will not be an access this week to repair the Recycler. Beam studies will continue through Wednesday night with shot setup expected sometime on Thursday Owl or Day shift.

Wed 02/27 07:30-10:00 Online cluster down for upgrade to RAID array
Wed 02/27 13:00-15:00 pDAQ system devoted to L3 cDAQ tests. Contact person: Gustaaf Brooijmans.
Wed 02/27 15:00-18:00 DAQ system devoted to L2 tests. Contact: Reinhard Schweinhorst.

After DAQ tests, the system needs to be returned to normal and thoroughly checked for DAQ operations.

D0 shifts plan for this week:

  1. Captains and DAQ shifts are 24/7.
  2. Day and evening detector shifts are ON.
  3. Owl detector shifts Wed 02/27 are "on call". That means that shifters have to report to shift and, if agreed by Captain and detector groups leaders, could leave providing Captain with phone numbers where they can be reached during the shift.
  4. Starting from day shift Wednesday, 02/27 all shifts are ON.

If there are long periods (> 1 hr) of no beam in the Tevatron then continuation of the special Cosmics Run requested by G. Gutierrez can be conducted - see the Special Runs request binder. Note the SMT needs to be in unsuppressed mode. The request also asks for no Solenoidal field.

Control Room Activities

Captains are responsible with communicating with the MCR about end of stores. The MCR will inform the D0 control room 15 minutes before the store end, so that D0 is able to end run/reduce HV orderly. As soon as we are ready, D0 Captain has to call MCR and confirm that D0 is "ready for store termination". In order to maintain clear communication with MCR the Captain should be the only shifter communicating with the MCR.

In order to be able to remove runs with problems and not lose large data samples and because luminosity conditions change over a few hours, the "size" of the global run should be dictated by:

whichever comes first.

There is a new form in the electronic Control Room Logbook (restart the logbook to get the new button)
This form is intended for any "major" configuration change in any subsystem - examples might be installation of new hardware or firmware, addition of detectors, loss or regain of power supplies etc, etc. The keyword to search on is CONFIG_CHANGE. Contact Leslie Groer if more fields are needed.

Sustained, stable rates into L3 of 100 Hz have been achieved. Rate to tape is limited by the online system to about 40-50 Hz maximum. Global runs should use the prescale files established by the Trigger Meisters (TM). See the TM instructions for more details. If for some reason a different set of prescales is needed other than the standard ones, the TM should be notified.

DAQ shifters should use the DAQ Monitor to print out the L3 trigger page once every 2 hours during colliding beam running. The output file for these is stored as /online/log/mon/dmp.L3_Filter_n where n = a number that is incremented. Dump the file to the printer and write the date and time and stick this into a binder. The snapshot gives the total numbers of triggers seen by L3 for the run with the rejection and acceptance.

The Alarm Watcher is now active and will be issuing alarms warning of situations which would have paused a run - the run-pause step has not been activated yet but the verbal warning is issued. All alarms need to be investigated. If a HV channel has tripped, the run should be paused and the voltage reset. All occurences should be noted in the logbook, real and "fake". Captains and DAQ shifters should keep careful note of alarms (in the logbook) that are issued and that will be displayed in the Alarm display window:
  > setup d0online; start_daq alarm_display
Geoff Savage should be contacted if there are problems with the Significant Event Server of Alarm Watcher. See further instructions from Geoff.

By default, all crates should be included in global runs unless experts have removed them. Experts should be contacted if there are problems with any of the readout crates.
Note that there have been occassional problems with L2 crates going missing. During colliding beam operation, if problems cannot be resolved quickly by the DAQ and detector shifters the L2 on-shift person should be contacted immediately. If the L2 expert cannot be reached quickly (< 10 minutes), the L2 crate(s) should be removed from the run. The crates should only be reinstated in the global run if a L2 expert is present AND there is a "natural break" in the run.

Any work that will be disruptive to data taking during colliding beam (e.g. DAQ system tests, L3 tests, TFW work, sDAQ etc.) must be approved by the Run Coordinator.

All work in the MCH must be done with the full knowledge and presence of the experts and can only occur during times when there is no colliding beam. No cables, configurations, crates etc should be changed without the experts' explicit approval. Also the shift captain and DAQ shifter must be kept informed of any activity in the MCH (this includes test systems for L2, L3, STT, etc.) and this work needs to be recorded in the electronic logbook, with the names of the people involved.

Standard Trigger Files

For colliding beam, the default trigger configuration file is now:

global_CalMuon-4.10.xml
There are prescale files for 1, 2, 4, 5, 6, 8, 10, 12, 20, 30E30. There are also minbias_xxE30 files. See the Trigger Meisters' instructions. If there are problems contact the Trigger Meisters.

During non-colliding beam, the zero_bias_only trigger should be run with all available crates to exercise the DAQ as long as this does not conflict with commissioning or calibration efforts. Recording should be kept off unless tests of data transfer to the Feynman Computer Center are needed. These rates to FCC should be kept low (1 Hz) unless there is good reason to push data faster.

Planned Special Runs or Activities

Cosmic Ray Run for CFT + SMT - Gaston Gutierrez

Looper Study (Approved) - Ron Lipton/Naeem Said Requestor

See the Special Run Request Binder for details
Special run forms are available in the Special Run Requests binder in the control room.
