This run plan covers:
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:
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.
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:
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.
For colliding beam, the default trigger configuration file is now:
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.
