8 Commissioning 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 month per year heavy ion run 7 months per year pp Running schedule for the first 5 years –Regular pp runs at 14 GeV reduced luminosity between and 5*10 30 cm -2 sec -1 which will leads to event rates from 10 kHz to 200 kHz –2-3 years PbPb collisions luminosity of 5*10 26 cm -2 sec -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 Evolution of computing resources CMSATLASALICE MSS Disk CPU Now LHCC 2004 HR 2001 Now LHCC 2004 HR 2001 Now LHCC 2004 HR 2001
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)

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 ?
18 ALICE at LHC – Phase 2 Depending on physics results Upgrades: detectors, FEE, DAQ, trigger Example: detector covering large rapidities Probe initial partonic state in a novel Bjorken-x range ( ): –nuclear shadowing, –high-density saturated gluon distribution J/ψ ALICE PPR CERN/LHCC GeV SHLC: shutdown (2012 ?) + upgrade
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/
