Goals &
End of the

2. common stable "dry" operation of complete detector 1. 1st test data with complete detector on tape
2. reasonable good workingpoints established 1. stable common DAQ

2. production run

Activities technical operation of SC, gas, readout, ...
noise, dead channels,
cabling tested & fixed - 1 week of commontechnical operation without beam
"dry run"
- fix problems
- revise docu - SD specific calib runs - ECAL calib
- ITR HV training
- VDS/ITR spars. (SLT) - common data taking
- ECAL calib & ITR HV training 1. take a muon enriched data sample (1 week, SLT): complete detector (incl. ITR) 1. Golden Min Bias run (1 week)
2. prepare for pTr + SLT operation:
1 week stable running (DAQ) with pTr + SLT
1. dedicated FLT
commissioning
2. first 1+2 track
production run ... 1. 1+2 track production run
various wire comb.
2. prepare FLT usage of ITR and muon pixel and study FLT pair trigger

Data taking standalone tests common operation test runs

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 reviewcomm. needs of SG
-> detailed run plans
2. regular RC meetings
3. usable DQM 1. routine running
2. prepare run & shift plans until April 02 consider & prepare in detail trigger commissioning steps routine routine routine routine

Analysis
Issues --- --- analysis of MinBias data: calib & align.
-> feedback - calibration
- alignment
- FLT studies - muon eff
- pTr efficiencies
- Gold. Min Bias run - J/Psi eff., resolution - J/Psi
- FLT - FLT efficiencies Physics

General Remarks

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

* default trigger 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

* Main Goals/Milestones

end of Sep 2001: subdetectors operational
end of 2001: detector (without triggers) commissioned incl. DAQ and DQM
end April 2002: default 1+2 trigger in stable operation, efficiencies understood, already some J/Psi physics data on tape

* List of Abbreviations

SD - subdetector
SG - subgroups
RC - run coordination
WoB - Week of Beam operation
HS - regular HERA-B shift (8h)
ES - expert shifts (8 - 12h)
EoC - expert on call (1 week)
pTr - preTrigger (ECAL & Muon)

* Footnotes

[1] reduced shifts - might be feasible in periods where lot of experts are around:

just one person on regular shift
experts expected to be present for longer continuos time periods, esp. while operation
