18 Trajectographe à silicium Des capteurs en silicium très finement segmentés (rubans et pixels) permettent de suivre la trajectoire des particules et de mesurer leur impulsion Comparable à un appareil photo à 70 millions de pixels prenant 40 millions de clichés par seconde! But: mesurer les trajectoires & l impulsion des particules chargées Tracker

19 EM calorimeter xtals, lead tungsten oxide, 80% metal: transparent

21 Software structure/layers non-HEP specific software packages Experiment Framework Event Det Desc. Calib. Applications Core Libraries Simulation Data Mngmt. Distrib. Analysis Every experiment has a framework for basic services and various specialized frameworks: event model, detector description, visualization, persistency, interactivity, simulation, calibration, etc. Many non-HEP libraries widely used Applications are built on top of frameworks and implementing the required algorithms Core libraries and services that are widely used and provide basic functionality Specialized domains that are common among the experiments ( some in grid middleware) GRID Middleware OS & Net services common for expts. expt. specific grids/networks 30 June Grid 2008; H F Hoffmann, CERN Software and Grids

22 What to do with the data? Global collaboration Hans Hoffmann, CERN honorary22 individual physics analysis batch physics analysis batch physics analysis detector Event Summary Data (ESD) raw data event reconstruction event reconstruction event generation, simulation event generation, simulation event filter (selection & reconstruction) event filter (selection & reconstruction) processed data Analysis Object Data (AOD) (extracted by physics topic) Detector calibration alignment Detector in the Grid

23 Global collaboration Hans Hoffmann, CERN honorary July 2008 Digital camera, 150 M pixels, observing: 10 9 frames/s, recording selected frames: 200/s, ~1 GB/s recorded volume Concorde (15 Km) Balloon (30 Km) CD stack with 1 year LHC data! (~ 20 Km) Mt. Blanc (4.8 Km)

24 Computing GRID the size of the planet!

25 Global collaboration Hans Hoffmann, CERN honorary International cooperation: Russian workers converting shells to CMS detector parts

26 Structure CMS est constitué de plus de tonnes dacier – en comparaison la Tour Eiffel ne pèse que tonnes! Ce socle a été réalisé au Pakistan et est arrivé au CERN par bateau, train et camion! Contribution from Pakistan

27 CMS Global collaboration Hans Hoffmann, CERN honorary

28 ALICE: an ultra-sensitive eye on the Universe: Quark-gluon plasma?

29 31 countries, 109 institutes, 1000 scientific/technical participants 29

30 LHCb: an asymmetrical perspective

31 What is the Grid? The World Wide Web provides seamless access to information that is stored in many millions of different geographical locations In contrast, the Grid is an emerging infrastructure that provides seamless access to computing power, software and data; distributed over the globe enabling CERN users to work from home as if at CERN CERN in everyday life H F Hoffmann CERN honorary

32 Marek Domaracky CERN in everyday life H F Hoffmann CERN honorary

33 CERN in everyday life H F Hoffmann CERN honorary 33 e-Science is about more than networks, Grids, High Performance Computing...; e- science is about global collaboration in key areas of science and the next generation of infrastructure that will enable it. John Taylor, Director Research Councils, UK, 2000 Provide equal access to the data, software, compute power.. to all participating scientists

34 large data repositories; data services communication means facilities, instruments, services e-libraries archive/curation centres people & VOs skills & training computers (HPC; HTC); computer aided services interoperable open software networks, services, dark λ Multidisciplinary Collaborations: Common objectives Open sharing Critical mass Trust and respect >Best efforts Quality Assurance Service-oriented e-science infrastructure ingredients CERN in everyday life H F Hoffmann CERN honorary
