This run plan covers:

From : Eve shift Friday June 28, 2002

Through: Owl shift Tuesday July 2, 2002

Note: Dmitri Denisov will be away from the lab June 22-July 3 and
Leslie Groer will be Acting Run Coordinator: pager (630) 218-8421.

Current Situation and Plans

All shifts are to be manned 24/7 throughout the weekend. Tevatron plans are for shots and stores all weekend through Tuesday 08:00, at which time they will do three shifts of beam studies.

The water leak was located during the Friday (June 28th) supervised access. One of the SMT heat exchangers was disconnected from the water manifold. Ops crew successfully closed up in record time - less than two hours.

Magnet polarities (through Tuesday July 2nd owl shift):

   Solenoid = Reverse
   Toroid   = Forward

There are three trigger configuration files to use:

global_CalMuon-7.40.xml

global_CalMuon-noL2-7.40.xml

global_CalMuon-noL2MU-7.40.xml

For the first store(s) going from Friday evening through Saturday owl shifts, the global_CalMuon-noL2MU-7.40.xml is to be used. From the Saturday day shift, there will be L2 and Muon experts around, so the DAQ Shifter should run with global_CalMuon-7.40.xml.

Addendum: We will run the global_CalMuon-noL2MU-7.40.xml until further notice. The L2 muon crates frequently get stuck in a state where the SCL init does not help - usually at L1 rates above 200 Hz.

There is a L2 expert on-call 24/7 if help is needed in getting L2 (Cal, Muon and Global) read out. A reasonable effort should be made to keep L2 in the run. Separate trigger configuration files are available if all or part of L2 cannot be made to read out in a timely fashion.

7.40 is a new trigger configuration not yet tested with beam, so new sets of prescale files need to be created and tuned. Initial 7E30 prescale sets are ready for shot setup and early store. If help is needed with prescales, page Elizabeth Gallas (call at home if at odd hours).

Addendum: There are now three prescale sets tuned from store 1482 - 2E30, 4E30 and 8E30.

For the first couple of stores this weekend, we will need to tune the prescales for optimum data taking. The maximum rates into and out of L3 have yet to be determined. Elizabeth has suggested the following schedule:

Beam conditions
Shot Setup Collisions

Day Page Page

Eve No Page Page

Owl No Page Home

	Beam conditions
	Shot Setup	Collisions
Day	Page	Page
Eve	No Page	Page
Owl	No Page	Home

During non-colliding beam, the zero_bias_only-1.3.xml trigger should be run with all available crates to exercise the DAQ as long as this does not conflict with commissioning or calibration efforts.

During extended periods of time (>1 hour) when no beam is expected in the Tevatron, the cosmics-1.40.xml trigger should be run with all available crates and Recording On as long as this does not conflict with commissioning or calibration efforts.
