CERN where antimatter is made

• CERN is about fundamental scientific challenges
  in Particle Physics

Front page, September 19, 2002More Sci- Than Fi,
Physicists Create Antimatter Physicists working
in Europe announced yesterday that theyhad
passed through nature's looking glass and had
createdatoms made of antimatter, or antiatoms,
opening up thepossibility of experiments in a
realm once reserved forscience fiction writers.
Such experiments, theorists say,could test some
of the basic tenets of modern physics andlight
the way to a deeper understanding of nature ...
The new research was conducted by physicists at
CERN, theparticle physics laboratory outside
Geneva.

LCG The LHC Computing Grid Project

• a geographically distributed computing facility
• for a very large user population of
  independently-minded scientists
• with independent ownership/management of the
  different nodes
• each with different access and usage policies
• and serving multiple user communities

Conclusion

• CERN creates new technologies of value to
  Industry
• CERNs Grid RD may create disruptive
  technologies
• Industry creates new technologies of value to
  CERN
• CERNs Grid RD dependent on industrys inputs
• Win-win situation for CERN and Industry to
  collaborate
