  1. CERN related research program in 2006-2011Nuclear Physics • High energy nuclear physics • ALICE experiment • Installation and Commissioning • Data taking • Data analysis – offline computing • Physics program • HENP after 2011 • Theory • ISOLDE activity

  2. ALICE at LHC • First collision: mid 2007 • ALICE lifetime = 10 years

  3. ALICE - budget

  4. Installation and Commissioning – 2006 (1) • Installation of the TPC FEE • Dec. 2005 – Feb. 2006 • 3 people for 2 months 1 person-month @ CERN: ~35 kNOK

  5. Installation and Commissioning – 2006 (2) • TPC/HLT pre-commissioningwith laser beams and cosmics • Feb. 2006 – Aug. 2006 • 1-2 people for 2-3 months • Installation of the TPC RCUs • Summer 2006 • 1 person for 2 weeks

  6. Installation and Commissioning – 2006 (3) • Installation of the PHOS FEE and RCU • Spring 2006 • 2 people for 2 months • PHOS pre-commissioning and calibration • PS beam in summer 2006 for 8 weeks • 1-2 people for 2.5 months (shifts)

  7. Detector installation plan

  8. Commissioning - 2007 • Commissioning of the front-end electronics • TPC • PHOS • Installation and commissioning of the HLT • Full connectivity • 30% of computing power • First pp collisions in summer 2007 • First PbPb collision in 2008

  9. Running scenario • First pp collisions in 2007 • 1 month per year heavy ion run • 7 months per year pp • Running schedule for the first 5 years • Regular pp runs at 14 GeVreduced luminosity between 1029and 5*1030 cm-2sec-1 which will leads to event rates from 10 kHz to 200 kHz • 2-3 years PbPb collisionsluminosity of 5*1026 cm-2sec-1 which leads to an interaction rate of 4 kHz • 1-2 years ArAr • 1 year pPb like collisions

  10. Data analysis – offline computing • Scandinavian offline computing contributed through NDGF (Nordic Data Grid Facility) • Agreed sharing ATLAS/ALICE 50%/50% • ALICE computing needs approx. half of ATLAS but half the number of collaborators • LCG resource status: 50% shortfall for ALICE

  11. ALICE ATLAS CMS HR 2001 LHCC 2004 HR 2001 LHCC 2004 HR 2001 LHCC 2004 Now Now Now CPU 16 26 35 17 41 65 26 40 55 Disk 2 9 13 3 21 24 4 14 26 MSS 5 11 11 20 11 11 10 16 17 Evolution of computing resources

  12. Present status of pledged resources • Tier 0 at CERN • ALICE requirements satisfied, including peak for first pass reconstruction • Tier 1 and Tier 2 • As declared to LCG and presented to RRB • CAF not included

  13. Physics program • Flow analysis (TPC, HLT) • High pt physics • Nuclear modification factor direct  and 0,  (PHOS, TPC, HLT) • Di-jets, gamma-jets (PHOS, TPC, HLT) • Heavy flavour • Open charm production (TPC, ITS, HLT) •  production (TPC, TRD, HLT) • Ultraperipheral collisions (TPC, SPD+trigger detectors, HLT)

  14. Nuclear Theory • Relativistic heavy ion collisions and quark-gluon plasma • Initial state • Final Freeze Out • Collective, Fluid Dynamical properties (“Third flow component”) • Phase transition dynamics

  15. Personell - staff

  16. ALICE - budget

  17. HENP after 2001 • ALICE running plan • pp or pp-like run at 5.5 TeV • Light AA system • dA • Low energy PbPb • Another high energy PbPb • ALICE upgrades ? • CBM at FAIR/GSI ? • Astrophysics experiment ?

  19. CBM experiment at FAIR/GSI • Facility for Antiproton and heavy Ions Research • Planned commissioning: 2010 – 2015 • CBM experiment • super-dense baryonic matter • in-medium properties of hadrons

  20. Dense Matter in the Universe • Mergers of binary stars – the ultimate nuclear collision • evolution depends on the equation-of-state of the matter inside the star • large differences between normal neutron stars and selfbound stars • different pattern of mass transfer • observable via gamma bursts, gravitational waves, ...? in 2020? astro/-ph/0403374
