The impressive progress on the construction, installation, and commissioning of the detector, as well as on the preparation for the data collection, the distributed analysis and the physics, will be covered over this week
As the details we will be presented all ‘first hand’ by those doing actually the work, there is no point for me to cover any of this now…

New LHC machine schedule
A new LHC schedule and turn-on strategy was presented to the CERN SPC and Councilthree weeks ago
The experiments were informed only shortly before, and allowed to communicate it just after the SPC meeting
The main features of the new schedule are:
- The beam pipe closure date will be end of August 2007 (instead of end of June 2007)
- After that there will still be a few weeks of controlled access to the cavern
- This is followed by an LHC commissioning run with collisions at the injection energy (450 + 450 GeV), until the end of 2007
- Then there will be a shut-down (typically 3 months) during which the remaining machine sectors will be commissioned without beam to full energy (7 TeV)
- After that the LHC will be brought into operation for the first physics run at 14 TeV, with the aim to integrate substantial luminosity by the end of 2008
The LHC Machine Advisory Committee (MAC) has strongly endorsed this new start-up strategy asthe most efficient way to reach 14 TeV collisions
The SPC stressed that the goal should be several fb-1 integrated luminosity at the end of 2008

Milestones for the machine
- Sectors 7-8 and 8-1 will be fully commissioned up to 7 TeV in 2006-2007. If we
continue to commission the other sectors up to 7 TeV, we will not get circulating
beam in 2007.
- The other sectors will be commissioned up to the field needed for de-Gaussing.
- Initial operation will be at 900 GeV (CM) with a static machine (no ramp, no
squeeze) to debug machine and detectors.
- Full commissioning up to 7 TeV will be done in the winter 2008 shutdown

We now have enough information to produce a consolidated plan for
commissioning.
Three quarters of the machine has been liberated for magnet
installation and interconnect work is proceeding in 2 octants in
parallel. Magnet installation is now steady at 25/wk . Installation will
finish March 2007. The machine will be closed in August 2007.
Every effort is being made to establish colliding beams before the
end of 2007 at reduced energy. The full commissioning up to 7 TeV
will be done during the 2008 winter shutdown ready for a Physics run
at full energy in spring 2008.
CERN management’s conclusion
(Presented last week by J Engelen at theCracow Physics at LHC conference)
10 July 2006 ATLAS Plenary 17
W e Z ee
(Data taking efficiency (machine x detector) of 30% includedEfficiency of all analysis cuts included)
s = 900 GeV, L =1029 cm-2 s-1
Given this new schedule situation, ATLAS stated that the start-up strategy should be such that the useful integrated luminosity at 14 TeV at the end of 2008 will be maximized
This points towards preferring a few weeks of stable running conditions at the injection energyas compared to possibly lengthy attempts to reach the maximum possible beam energy of 1.1 TeVbefore the full commissioning of LHC power components in the winter shut-down
Primarily the run in 2007 will be a detector and computing commissioning run, much more than a physics run

Overall financial situation (more details in the CB)
Main financial framework (a simplified summary)
ATLAS construction budget initial MoU 1995 475 MCHF
updated baseline contributions 468 MCHF
Cost-to-Completion (CtC) evaluation 68 MCHF(in addition to deliverables, accepted by the RRB in October 2002 based on the Completion Plan)
Main funding issues today
There are remaining outstanding contributions to the baseline & Common Fund 9 MCHF
Not all the calculated CtC shares have been pledged, in fact the situation only looksquite good because CERN has committed 5 MCHF more than its calculated share
The following table shows the details

Updated Cost to Completion estimates
The RRB was warned in the April 2006 meeting that the ATLAS management is re-evaluating thefinancial situation and evolution since the CtC estimates accepted in October 2002
The situation as we understand it now is that there are new overcosts projected at the level of 4.4 MCHF for the completion, over the 68 MCHF estimated in 2002
Further delays in installation work beyond August 2007 would require additional resources for manpower to be paid (order 200 – 400 kCHF per month)

Note that these overcosts could still be absorbed within the initial completion plan provided that all FAs would provide the full calculated share of the initial CtC funds, given the extra contribution provided by CERN
Alternative funding schemes have been discussed with the CB Audit Group, and will be discussed in the CB meeting
Restoration of the full TDR detector
The RRB has been reminded regularly that for the standard LHC design-luminosity the ATLASdetector will have to be restored to its approved TDR configuration
At the time of the establishment of the Completion Plan (October 2002), this was estimated tobe in the 20 MCHF range (usual CORE material accounting)
The ATLAS management will have to examine and coordinate plans for reaching the full detectorin the coming months; we are also requested to give first indications about this at the next RRB

During this ATLAS Week it will become evident that the ‘Operation Model’ is being implemented in a gradual and pragmatic way
(Details can be found at http://uimon.cern.ch/twiki//bin/view/Main/OperationModel )
10 July 2006 ATLAS Plenary 24
Steps on the way to the gradual implementation of the Operation Model (OM)
Setting up of the five activity areas:
Detector operation Will evolve from the present commissioning organization which iswell functional and growing
Trigger Will evolve from the present TDAQ system and physics-relatedtrigger activities, and the TDAQ management changes underway anticipate the reorganization
Computing Basically existing, OM adaptations being implemented
Data Preparation Is being set up now, will regroup many present activities
Physics Basically existing, OM adaptations being implemented
An important step was the introduction of explicit combined Trigger and Physics Weeks driving this central activity for preparing the data taking era
Both the cosmic ray running, gradually starting at Point-1, and the forthcoming large-scale ‘Calibration Data Challenge’ simulations can be seen as important ‘shake-down’ actions for the OM implementation
We have also initiated a major effort (OTSMOU Working Group) to define the fair sharing of all operation tasks between all the Institutions, and to review the M&O sharing for the running phase
This will include a definition of obligations for new Institutions joining ATLAS in this new phase
10 July 2006 ATLAS Plenary 25
Main goals in very general terms
Get a global view of where we stand in all aspects in the preparations for our experiment
Recall that global aspects concern us all, and that we need to care about much more than just the areas of our own activities
This OW should make us particularly aware of the ongoing transition from construction to operation
The major focal points are clear
- Completion of the construction- Assembly, integration and commissioning of the detector components- Computing and software- Trigger and physics preparation
- Installation- Commissioning
- In general: preparation of the operation phase
Last, but not least, enjoy a stimulating and motivating time together
Recalling the Goals of the Overview Weeks:
