This run plan covers:

From : Eve shift Jan 02, 2001

Through: Eve shift Jan 03, 2001

Toroid: On Forward

Solenoid: On Forward

Current Situation and Plans

Store 875 is colliding. The store will remain until 08:00 Thursday morning with accelerator studies starting at 06:00 or 07:00 and planned to continue until 08:00 Friday. If the beam is lost then studies will start earlier. Shot set up is planned for Friday DAY shift.

The main task of the shift crew is to collect data in stable global runs. Maximum input rate into Level 3 will be dictated by stable running and currently is about 12-15 Hz. By default, all crates should be included in global runs unless experts have removed them, with the exception of the CFT (see below). Experts should be contacted if there are problems with any of the readout crates.

The FPD can move their Roman pots not earlier than 1/2 hour after beginning of store. There is a plan agreed to by Run Coordinator and the Beams Division (see Standard Run Plan). Before any pot motions the MCR and CDF must be informed. In particular, CDF would like to be informed about which pots are being moved.

The major shift tasks are:

• Keep DAQ running collecting colliding beam data and cosmics or beam halo data. Recording must be kept ON for all runs.
• All test runs and trigger configurations must be stopped and freed before starting the global data taking run with colliding beam. CFT special runs may only start after the global run is going.
• Captains will inform the DAQ shifter when the begin store command should be issued (after scraping is complete) and when to issue the end store command which should be done before high voltages are ramped down or before accelerator studies begin.
• Include all front-end and readout crates in the data taking; experts have to be called in the case of problems.
  Detector experts should clearly indicate the status of crates on the white board in the Control Room.
• Conduct Captain and shifters' walkthroughs, fill check lists and report all problems to experts.
• Run all detectors at full voltages (beam conditions permitting).
• Monitor beam losses and silicon radiation doses.
• Help experts with short controlled accesses.
• Run all detector Examines under Detector shifter control. Report any problems to the subdetector coordinators. Until further notice the Global Examine is broken and need not be run.
• When there is no beam, calibration runs should be taken. These runs should be coordinated with the DAQ shifter.
• From now on, the offline farms will process all data in global physics runs, hence captains are no longer responsible for making shiftsets. If there are special runs (cosmics, halo, etc) that needs to be reprocessed on the farms, then the persons requesting the special data collection is required to fill in the shiftset request form and to send mail to d0-farms@fnal.gov.
• People have requested that the shift summary report still be mailed to d0shifters, as well as posting on D0news. If many people on d0shifters do not wish to see this, we will set up a separate mailing list.

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, STT, etc.) and this work needs to be recorded in the electronic logbook, with the names of the people involved.

CFT Operations

During colliding beam:

1. The CFT shifter will communicate with the Captain and DAQ shifter and request whether the CFT crates (0x50,0x51,0x52,0x53) are to be included in the primary global run or not.
2. If desired by the CFT shifter, CFT crate(s) will be excluded from the global run and sDAQ runs with the CFT only may be run independently.
3. If independent CFT pDAQ runs or unsuppressed CFT running in the global runs are requested, the Run Coordinator must approve the run. This does not apply to sDAQ runs.
4. Once debugging work with one or more CFT crates has been completed and the crates are available for more than an hour for regular running, the CFT shifter should inform the Captain and DAQ shifter that the crate(s) are available for global runs. These crates must be run in suppressed mode. The global run should not be stopped just to include these crates, but the next natural, convenient break in the run should be used to include the crates.

Standard Trigger Files

For colliding beam trigger configuration file is

global_CalMuon-3.10.xml

There are prescale files for 1, 2, 4, 6, 8, 10E30 and a panic file. For example, for luminosity between 3E30 and 5E30 use prescale file 4E30 and similar for other prescale files. If there are problems with the v3.10 file, contact the Trigger Meisters.

For cosmic ray running use one of two files (depending upon L2 crates status):

cosmics-1.1.xml - does not include the L2 crates

cosmics-1.2.xml - contains the L2 crates in non-readout mode

proton_halo_only-1.2.xml
