Sign Off

• A number of infrastructure sub-systems have
  already been commissioned or are in the process
  of being so
• CV
• Cryogenics plant on surface
• Cryogenics in USA15, Magnet equipment
• Cranes
• For these we envisage a sign off procedure only
• To collect the performance parameters
• To understand open issues and problems
• To integrate them in a uniform documentation
  scheme, easy to trace back

9
Sign Off

• A formal procedure to make sure that
• Installation (if any) has been properly done
  e.g. w.r.t. TC procedures (Install. DB, etc)
• Proper grounding safety issues have been taken
  into account
• Documentation is available
• Technical and maintenance documentation for H/W
  and S/W
• User guides, operational procedures, including
  the test procedures
• Planning for maintenance and responsibilities
  are defined
• Performance is according to specifications
• Or we understand where, how, possibly why, there
  is a disagreement
• We know what are the open problems and issues
• And what actions can be defined
• It is clear who is authorized to use the system
  once commissioned
• Sensitive items ID cooling, LARG high voltage,
  TILES Cesium system,
• The sign-off procedure may occur in several
  steps
• For a complex WP one may envisage intermediate
  milestones, hence sign offs
• Associated to a repetitive aspect
• E.g. ROD crates, FE electronics, muon chambers.

Sign Off
In the Work packages document WP
outcome (Agreed before WP activation)
Final sign-off procedure

• Installation report
• Inventory, grounding, safety,
• Performance specifications
• Expected functionality
• Quantitative performance figures
• Test report
• Checklist of tests and results
• Operational documents
• Indicates who is responsible, who to contact for
  problems
• Maintenance procedures/plan
• Pointers to relevant documentation
• Operational procedures
• Test procedures
• Component manuals
• List of open issues/problems

Weekly meetings at Point 1

• Make use of sub-system installation meetings to
  follow phase 1 sub-system specific commissioning
• Phase 1 has too many WPs to concentrate their
  follow up in a single weekly meeting
• Avoid proliferation of meetings
• Assume that emphasis will shift from installation
  to commissioning
• Weekly meeting
• The same morning as the follow-up of the
  management meetings for UX15 (EAM) counting
  rooms (CRM)
• Use for topical discussion, sign off, follow
  sub-systems w/o an installation meeting (e.g.
  DSS, DCS, DAQ, trigger)

• Minutes can be found at
• Experimental Area Management (EAM)
  http//atlas.web.cern.ch/Atlas/TCOORD/Activities/L
  ogistics/G1/EAM_minutes_index.html
• Counting Rooms Management (CRM) ATC-C-IM-0001
• Inner Detector ATC-GE-MM-0132
• Calorimeters ATC-GE-MM-0125
• Muons ATC-GE-MM-0126

12
Monthly meetings

• Start discussion of phase 2 commissioning - gt
  monthly meeting
• Overall status and issues to be escalated TMB,
  EB

13
Potential difficulties

• Elaborating the commissioning work to be done
  needs time and some distance with the daily work
  on site.
• Collaborators involved in commissioning in the
  sub-systems are too often overloaded by many
  other things (e.g. production/installation
  tasks).
• More effort needed to prepare the functional
  work packages following installation.
• The new installation planning is very tight (no
  float anymore). This can jeopardize the tests and
  the commissioning. Determine priorities in the
  tests.
• Test programs, software and analysis tools ready
  in advance is an important asset.
• Centralized management of the computers and
  network at point 1 is mandatory to avoid
  confusion.
• Need of a centralized support for the counting
  rooms.

14
Phase II commissioning

• Define a reasonable end of Phase I for the
  sub-systems.
• We wont go sequentially Phase 1-gt Phase 2.
• System integration
• Partitioning the ATLAS detector Trigger
  (CTP,LTP), DAQ (RCD), DCS, DB
• Integration Sub-detectors DAQ DB Offline
  data
• Integration Sub-detectors central DCS DBs
• Operations L1calo LARG TILES (Workshop Feb..
  1st 2005, next in April)
• Functional tests
• Noise tests and Calibration Pulse tests on large
  scales involving sub-detectors and L1. Involves
  ROD crate DAQ.
• Partial cosmic runs Tiles Muon Barrel sector
  13 ( alignment) LARG (later). Involves ROD
  crate DAQ.
• Toroid tests (after completion) Sub-systems
• Infrastructure (cooling, ventilation)
  sub-systems (detectors, electronics, TDAQ, DCS)

15
Phase II commissioning

• More local combinations
• LARG cryogenics
• Magnets cryogenics
• ID gas system
• Muons gas system
• Work organization
• Many ideas are around and we already feel the
  pressure to take cosmics asap. Need a clear
  formulation (WP) to decide the priorities and
  build a planning.
• Working groups being organized
• L1, DAQ or DCS oriented
• Detector performances and physics coordinators
  calibration data, cosmics
• Elaborate WPs. Monthly meetings to discuss and
  plan them.
• Role of commissioning coordination
• Need a place to operate the detector being
  commissioned (proto Control Room)
• .

can be considered not as Phase II, but as A
natural extension of Phase I
16
Conclusion

• Continue to initiate the mechanics of WPs with
  the various ATLAS systems. Milestone of June,
  before the barrel calorimeters move to IP.
• The success of a well commissioned ATLAS system
  is the result of the sum of many detailed
  tasks.They have to be well thought and prepared
  to be meaningful for the future.This required
  more collaborators involved in these aspects. The
  acknowledgment of this work is of importance.
• Centralized management of the computers and
  network at point 1 will become soon mandatory to
  avoid confusion.
• Need of a centralized support for the counting
  rooms.
• Start thinking seriously soon to a proto control
  room.
