For the remaining stores until the shutdown the goal is stable, global data taking. No changes to detectors, electronics, software/software parameters should be done without specific approval of the Run Coordinator. Downtime should be minimized to fixing serious problems which prevent data taking. Captains are charged with enforcing this goal.

This run plan covers:

From : Eve shift Sep 29, 2001

Through: Eve shift Sep 30, 2001

Current Situation and Plans

Current Magnet configuration:

Toroid: Reverse

Solenoid: Forward

Shot setup expected Sat night after the controlled access. Goals for the beginning of the shift are to get to stable data taking with as many of the crates as possible, with the caveat that unstable crates should be removed from the run and the experts contacted.

Priorities for the current Store

Global Runs
The default running condition is with the global trigger list, with all available crates. The current list is the global_CalMuon-1.4.xml trigger which now includes L1 central di-muon triggers. Keep the prescales according to the instructions of the Trigger Meisters and see the instructions for tuning rates depending on beam conditions. Use all available L3 nodes by entering "0" in the run parameters box - this should get 9 nodes if no-one else is running. Tests of the L3 system indicate that we should be able to sustain rates of 15-20 Hz but with the instabilities seen in the DAQ lower rates might need to be maintained to get stable running. Keep the unprescaled triggers and tune the prescaled triggers to maintain the desired output rate based on the instructions in the trigger files.

Special No-solenoid field run
Assuming we still have colliding beam, the Day shift should conduct a special run for Jet energy scale calibrations. Take 100k events.
Solenoid: Off, Toroid: Reverse. Contact Gregor Geurkov to change the luminosity electronics for the no-solenoid field condition.
Trigger: global_CalMuon-1.4.xml, but prescale away the muon and the CFT coverage triggers and enhance the jet and EM triggers. Keep the min-bias and zero-bias triggers. In particular the triggers to keep are:
CEM(1,5), CEM(1,10), CEM(1,20), CJT(1,5), CJT(1,10), CJT(1,40), CEM(2,5), CEM(2,10).
Crates: Make sure that the calorimeter crates have the correct pedestals and that hot cells have been suppressed. Other crates can stay in the run but are not critical.
After 100k events, turn the solnoid on again and continue with normal global runs.

FPD plans to regularly put their pots in during stores and depending on shifter availability. See the FPD pot motion run plan. At the end of the current store they intend to do a quick pot insertion in just a couple steps.

Special Note about Crates: Crates that are too unstable i.e. they cause a hang (FE busy or missing in the data) of the DAQ more than twice an hour, are not to be run in global runs with colliding beam unless (i) experts are present and (ii) actively working on debugging the problem. The crate can be run in a separate run for debugging if it does not intefere with the global run.

Priorities when NOT in Store

Scott Snyder has identified a memory leak in COOR but will not release a fix for the next few weeks as he will be out of the country. The suggestion is to restart COOR once every day or two.

Allow detector experts to work on their crates.

Cosmic Ray runs if no beam. Halo runs if there is a proton or anti-proton only store.

Ensure detectors take decent calibration files in preparation for collisions.

There are (temporary) instructions from Moacyr Souza <moacyr@fnal.gov> on restarting the L3 monitor that feeds information to the DAQ monitor display if the process hangs. If the information is not updating in the Level 3 page of the DAQ display:

Login in to d0ol03 using the d0run account
Make sure that the server is not running, by typing
ps -aux | grep l3LumServer_x
If you do see the process running, kill it by using
kill -15 xxxxxxx
where xxxxxxx is the process id number for the first 'l3LumServer_x' process.
After this issue:
source /home/moacyr/l3server_source

This should restart the server.

General note for special runs: Experts need to be identified for any special run and should provide a means of contact (pager preferably). If there is trouble starting up a special run and experts cannot be located or contacted, then the run should be put "on hold" until further notice by the Commissioning coordinators.

For no colliding beam these are the trigger files:

Cosmics cosmics-1.0.xml

Zero-bias zero_bias_only-1.3.xml

Proton store proton_halo_only-1.2.xml

Anti-proton store pbar_halo_only-1.2.xml

Shift Captains must make a SAM dataset for good runs at the END OF EVERY SHIFT. Use the SAM dataset web page (see the Standing Instructions for details).

Note to Captains: The Operations Technicians are taking care of the safety walk through represented on the 3rd page of the Captain's checklist. Captains are still responsible for safety walkthroughs on the first two pages including the 2nd floor of the Fixed Counting House. Heidi Schellman has put together a very useful Pictorial Guide to components in the Control Room and in DAB.
