9 10 July 2006ATLAS Plenary9 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… Integration work on one of the two SCT end-caps

10 10 July 2006ATLAS Plenary10 News from the LHC machine

11 10 July 2006ATLAS Plenary11 New LHC machine schedule A new LHC schedule and turn-on strategy was presented to the CERN SPC and Council three 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 ( GeV), until the end of 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 as the 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

12 10 July 2006ATLAS Plenary12 Last magnet deliveredOctober 2006 Last magnet testedDecember 2006 Last magnet installedMarch 2007 Machine closedAugust 2007 First collisionsNovember 2007 Milestones for the machine - Sectors 7-8 and 8-1 will be fully commissioned up to 7 TeV in If we continue to commission the other sectors up to 7 TeV, we will not get circulating beam in 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 LHC commissioning (Presented by CERN to SPC and Council)

15 10 July 2006ATLAS Plenary15

16 10 July 2006ATLAS Plenary16 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 The machine will be closed in August 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 CERN management’s conclusion (Presented last week by J Engelen at the Cracow Physics at LHC conference)

17 10 July 2006ATLAS Plenary17 W  e Z  ee (Data taking efficiency (machine x detector) of 30% included Efficiency of all analysis cuts included)  s = 900 GeV, L =10 29 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 energy as compared to possibly lengthy attempts to reach the maximum possible beam energy of 1.1 TeV before 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

18 10 July 2006ATLAS Plenary18 Overall financial situation (more details in the CB) Main financial framework (a simplified summary) ATLAS construction budgetinitial MoU MCHF updated baseline contributions468 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 looks quite good because CERN has committed 5 MCHF more than its calculated share The following table shows the details

19 10 July 2006ATLAS Plenary19 Status of the Cost to Completion funding (CERN-RRB )

20 10 July 2006ATLAS Plenary20 Updated Cost to Completion estimates The RRB was warned in the April 2006 meeting that the ATLAS management is re-evaluating the financial 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) SystemItem Item Over Run System Over Run System Total Cost System Over Cost MCHF % Magnet % Technical Coordination % Muon Big Wheels1.39 TCn installation manpower efforts at Point LArCC project % ATLAS % Not initially part of TCn The following table has been made by the CB Audit Group (see C Oram’s CB presentation) Largely due to the engineering contracts Workforce not available from CERN and Institutes

21 10 July 2006ATLAS Plenary21 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 ATLAS detector 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 to be in the 20 MCHF range (usual CORE material accounting) The ATLAS management will have to examine and coordinate plans for reaching the full detector in the coming months; we are also requested to give first indications about this at the next RRB

22 10 July 2006ATLAS Plenary22 Remaining is also the cash flow problem… (see M Nordberg’s regular presentations for details)

24 10 July 2006ATLAS Plenary24 Steps on the way to the gradual implementation of the Operation Model (OM) Setting up of the five activity areas: Detector operationWill evolve from the present commissioning organization which is well functional and growing TriggerWill evolve from the present TDAQ system and physics-related trigger activities, and the TDAQ management changes underway anticipate the reorganization ComputingBasically existing, OM adaptations being implemented Data PreparationIs being set up now, will regroup many present activities PhysicsBasically 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

25 10 July 2006ATLAS Plenary25 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:
