The Missions of CERN• Push forward the frontiers of knowledge

What are the constituent parts of matter? What was matter like during the first moments of the Big Bang?

• Develop new technologiesInformation technologies – the Web and the GridMedicine – diagnostics and therapy

• Train the scientists and engineers of tomorrow

• Unite people from different countries and cultures

The instruments used

2. Detectors : Gigantic instruments that observe and record the results of the collisions(particle trajectories, energy, charge…)

1. Particle accelerator : Boost particles to high energies and make them collide

E = m x c2

3. Computers : Collect, store, and send around the world the big quantity of data received from the detectors for data analysis.

The mandate of the Cooling and Ventilation Group concerns the operation and maintenance of the cooling systems, pumping stations, air conditioning installations and fluid distribution systems for the PS, SPS and LHC including their experimental areas and special cooling systems of LHC sub-detectors. It also provides service to the Computer Centre and some miscellaneous installations.
