The tool is particle accelerator (..a very powerful microscope)

The principle
Ernest Lawrence – 1930: “Whirling particles around to boost
their energies, then casting them toward a target like stones from a
slingshot is the most effective way to smash open atomic nuclei.”

The tools do not exist, scientist and engineers have to create them. This technological effort has important return for everyday life: • UHVacum ->

Putting the machine underground allows LHC to have a negligible environmental impact.

Why underground-2? To screen the particle detectors from cosmic rays (high energy protons of cosmic origin) For 1 GeV particles, the rate is about 10,000 per square meter per second

• To stop the particle produced by the collision

Beam on- data acquisition:
• Everybody out, access prevention;
• Monitoring effluents levels against environmental limits,
• Monitoring the machine and react to anomalies or incidents.

Beam off – maintenance:
• Plan before doing;
• Access restrictions;
• Personal radiological dosimetry;
• Training for emergencies.

Criogenic leak > risk of Oxygen lack
• 96 t of liquid Helium in the accelerator tunnel
• ~ 100 t of liquid Argon, Helium, Nitrogen in the 4 experiments
Risk of lung cold burns and risk of axphixiation
Amongst the measures: Helium spills simulations and test,
Oxygen lack sensors,
Personal breathing equipment.

conclusion • A large underground facility with complex multidisciplinary
safety challenges;
• Most of the time no people underground;
• World wide collaborations in different disciplines of physics and engineering to develop new technologies.
