CERN: where antimatter is made CERN is about fundamental scientific challenges in Particle Physics Front page, September 19, 2002 More Sci- Than Fi, Physicists Create Antimatter Physicists working in Europe announced yesterday that they had passed through nature's looking glass and had created atoms made of antimatter, or antiatoms, opening up the possibility of experiments in a realm once reserved for science fiction writers. Such experiments, theorists say, could test some of the basic tenets of modern physics and light the way to a deeper understanding of nature [...] The new research was conducted by physicists at CERN, the particle physics laboratory outside Geneva.

CERN: where the web was born Fundamental scientific challenges produce disruptive technologies

The world’s largest superconducting structure LHC – the Large Hadron Collider The world’s largest superconducting structure 27 Km of magnets with a field of 8.4 Tesla Super-fluid Helium cooled to 1.9°K Two counter- circulating proton beams Collision energy 7 + 7 TeV

CMS – The Compact Muon Solenoid 40 MHz 1 PetaByte/sec reduced online – event selection, data compression to a data recording rate of 100 Hz 1 PetaByte/year Four LHC Experiments start up – April 2007

The Large Hadron Collider - 4 detectors Requirements for data analysis CMS ATLAS LHCb Storage – Raw recording rate 0.1 – 1 GByte/sec Accumulating data at 5-8 PetaBytes/year (plus copies) 10 PetaBytes of disk Processing – 100,000 of today’s fastest PCs

Problem 1 – Cost Problem 2 – Number of components
