Coordination
Tasks & Run 
Coordination
1. activities under subsystem responsibility
2. anticipate periods without beam, e.g. HV
3. DQM definition documented
1. organize "dry run" with SG
2. DQM machinery operational
3. revised usable shift docu (RC&SG)
4. detailed run & shift plan until end of 2001
1. collect and review comm. needs of SG
-> detailed run plans
2. regular RC meetings
3. usable DQM 
1. routine running
2. prepare run & shift plans until April 02
1. prepare for Au MinBias week
2. consider &  prepare in detail trigger commissioning steps

General Remarks

* FLT incl. pretriggers: useful dedicated shorter studies are possible in each stage
    and will be handled with some priorities

* startup trigger scheme for 2002: 1 track from FLT + 2 tracks inside SLT (muon and electron pTr tracks)

* after this: include ITR and muon pixel into FLT, study FLT pair trigger, commission high multiplicity Veto, ...

* as default: contiguous shift periods (>= 6 shifts in one to two weeks)

* aiming for well definned period with a stable system / fixed configuration

* a questionaire to the subsystems++ is under preparation
   ==> feedback and detailed schedule by end of August 2002

* transparencies of talk in Copenhagen on June 22, 2001:  K. Ehret - Collab. Meeting
