1. The Norwegian ATLAS - HEPP project RECFA Meeting, NorwayOslo 15 May 2009 Farid Ould-Saada, University of Oslo HEPP Project leader and leader of NorduGrid-related Grid projects On behalf of many colleagues

2. Outline: Previous particle physics projects: reminder The High Energy Particle Physics (HEPP) Project Financial situation, very briefly The ATLAS HEPP team Some achievements, highlighted Conclusions and Outlook

3. Summary • Great progress on the construction, installation, and commissioning of the ATLAS detector, as well as on the preparation for the data collection, distributed analysis and physics • We are ready to tackle the LHC era • and really look forward to the first 100 pb-1

4. Previous Particle Physics Projects in Norway • Period 1998 - 2005 • Elementary Particle Physics Analysis (PL: Lars Bugge) • ATLAS @ LHC (including Grid from 2002) • BaBar @ SLAC • Delphi @ LEP  • HERA-B @ HERA (until 2003) • WA102 @ SPS (until 2001) • Theory: (from 2000) • ATLAS instrumentation (PL: Bjarne Stugu)

5. Current High Energy Particle Physics Project • Period 2006 – 2011 • A strategy document for CERN-related research covering the period 2006 to 2011 was presented to the Norwegian Research Council in 2003  Strategy document 2006-2011 • High Energy Nuclear Physics (PL: Dieter Rörich)  see presentation • New instrumentation (PL: Steinar Stapnes) see presentation • High Energy Particle Physics – HEPP project (PL: Farid Ould-Saada) http://koherens.uio.no/hep/hepp/ • “CERN-Related High Energy Particle Physics Research Programme in Norway: Resource Application 2006-2011”, Farid Ould-Saada et al., 2005 http://www.fys.uio.no/~farido/HEPP06-11/HEPP06-11.html

6. The Norwegian High Energy Particle Physics Project 2006-11 http://koherens.uio.no/hep/hepp/

7. HEPP in 2006-2009 • ATLAS experiment at the Large Hadron Collider (LHC) • Main Activity within the HEPP project  this presentation • High Energy Particle Physics Theory  see presentation • BABAR experiment at the SLAC B-factory • Still some publications from DELPHI and HeraB

8. Due to various delays (late start of LHC, ...) all post-docs were hired late both personnel and running costs affected (fewer people to travel). budget related to travel and presence at CERN affected (no shifts before 2009). Budget re-ajusted but More or less according to plans Financial situation

9. HEPP/ATLAS Project members

10. Permanent Staff - ATLAS 2 professors retired in 2008 + Lars bugge 50% + involved in other activities = Crisis in Oslo experimental group  Need at list 2 permanent positions!

11. ATLAS + Grid Post-doctoral positions • HEPP project plan foresees 3 Postdocs positions for the period 2010-2011 • Clear increase in # post-docs financed by the research council. Use to be 1-2 before 2005!!! • Substantial contribution from Grid projects  Synergy HEPP- Grid

12. ATLAS + Grid PhD Students: Current reporting period (RP) 08-09 • Finished during RP • Ongoing • Started during RP •  This is a good news! • Clear increase in # PhD’s. Used to be ~2-3 before!!! •  Still improvement needed • Contribution from Grid projects  Synergy HEPP-Grid

13. ATLAS Master Students: Current reporting period (RP) 08-09 • Finished during RP • Ongoing • Started during RP •  Good news: most of the finishing master students were offered a PhD grant: gRB’! • Question: Who will continue attracting students, motivate them and supervise them? • hence ensuring “sustainability” In other words ...

17. Another problem that Heart us and many others

18. Main Project Activities and milestones • Due to technical problems during the installation and commissioning of some superconducting magnets of the accelerator • the start-up of LHC had to be delayed from November, 2007 to mid-2008. • Several of the milestones related to the main activities described in the HEPP application document will thus be shifted, • typically by six months. Status: 2005 2007 2006/Q1 2008/Q2 2007/Q4 2008/Q2 2007/Q4 2011/Q4 2006/Q1 2008/Q2 2006/Q1 2008/Q2 2007/Q2 2008/Q2 2008/Q3 2009/Q4 2010/Q1 2011/Q4 Installation and Commission of Semi-Conductor T (SCT) 2006/Q1 2007/Q2 Commissioning of ATLAS 2006/Q4 2007/Q4 Operation of ATLAS, including SCT 2006/Q4 2011/Q4 Software develop., simul., analysis preparation 2006/Q1 2007/Q4 Computing infrastructure, data/service challenge 2006/Q1 2007/Q4 Data-taking with cosmic rays, analysis 2006/Q4 2007/Q2 Data-taking at Low luminosity, Phys. analysis 2007/Q3 2009/Q4 Data-taking at High luminosity, Phys. analysis 2010/Q1 2011/Q4  Due to the September 2008 incident, important milestones will be further shifted …  However progress has been made and some important milestones have been reached

20. Contributions to ATLAS Detector & Computing Infrastructure

21. One of the Norwegian contributions to the ATLAS “Semi Conductor Tracker” (SCT): Oslo, Bergen and Uppsala built 320 silicon modules ~ 15% of Atlas needs.

22. In 2006, the HEPP project's goal to build, install and test parts of the ATLAS SCT detector was reached Both barrel and end-cap integrated into the TRT (transition radiation tracker) on the surface and tested with cosmic rays The performance of the complete system, (tested for noise performance and cross-talk, efficiency, tracking and alignment), is very good Project members took part in Milestone cosmic ray tests and are heavily involved in commissioning. Impressive contribution of students to commissioning and shifts

23. ATLAS Cryogenics • Construction ofcryogenicstanks for ATLAS (NTNU, UiO, Industry) • aresuccessfullycompleted • The liquid nitrogen and liquid argon vessels have all been installed and routinely used in the successful tests of the barrel superconducting toroïd magnet system which was tested at full current at the end of 2006.

24. F. Ould-Saada Computing Grid infrastructure • The Nordic Data Grid Facility (NDGF) Tier 1 reached full operation in 2008. Seen as One site from CERN!

25. NDGF ARC-based (only) distributed Tier-1  the most effective of all Tier-1 clouds of ATLAS Physics distributed analysis already possible Synergy HEPP-Grid  A complete Grid environment for research • Efficient utilization of computing resources  Alex Read’s presentation
