Commissioning 8

Sign Off

A number of infrastructure sub-systems have already been commissioned or are in the process of being so: C&V 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


Commissioning 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.

Commissioning 11

Weekly meetings at Point 1

Minutes can be found at: Experimental Area Management (EAM):

http://atlas.web.cern.ch/Atlas/TCOORD/Activities/Logistics/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

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)

Commissioning 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.


Commissioning 14

Phase II commissioning Define a reasonable “end of Phase I” for the sub-systems. We won’t go sequentially Phase 1-> 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)


Commissioning 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, butas A natural extension of Phase I


Commissioning 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.
