LARGE HADRON COLLIDER

The LHC is exactly what its name suggests - a large collider of hadrons. Strictly, LHC refers to the collider; a machine that deserves to be labelled ‘large’, it not only weighs more than 38,000 tonnes, but runs for 27km (16.5m) in a circular tunnel 100 metres beneath the Swiss/French border at Geneva.

OVER HEAD VIEW

The LHC is physically located in a circular 27km (16.5m) long tunnel under the Swiss/French border outside Geneva, but as an international project and implimentation the LHC crosses continents and many international borders.
In the UK, engineers and scientists at 20 research sites are involved in designing and building equipment and analysing data.

Why the LHC

A few unanswered questions...

For the past few decades, physicists have been able to describe with increasing detail the fundamental particles that make up the Universe and the interactions between them.
This understanding is encapsulated in the Standard Model of particle physics, but it contains gaps and cannot tell us the whole story. To fill in the missing knowledge requires experimental data, and the next big step to achieving this is with LHC.

How the LHC works

Inside the accelerator, two beams of particles travel at close to the speed of light with very high energies before colliding with one another. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. They are guided around the accelerator ring by a strong magnetic field, achieved using superconducting electromagnets. These are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance or loss of energy. This requires chilling the magnets to about ‑271°C – a temperature colder than outer space.

Heavy-ion physics at the LHC

In the LHC heavy-ion programme, beams of heavy nuclei ("ions") collide at energies up to 30 times higher than in previous laboratory experiments. In these heavy-ion collisions, matter is heated to more than 100,000 times the temperature at the centre of the Sun, reaching conditions that existed in the first microseconds after the Big Bang. The aim of the heavy-ion programme at the LHC is to produce this matter at the highest temperatures and densities ever studied in the laboratory, and to investigate its properties in detail. This is expected to lead to basic new insights into the nature of the strong interaction between fundamental particles.

The LHC experiments

six experiments at the LHC are all run by international collaborations, bringing together scientists from institutes all over the world. Each experiment is distinct, characterised by its unique particle detector.
The two large experiments, ATLAS and CMS, are based on general-purpose detectors to analyse the myriad of particles produced by the collisions in the accelerator. They are designed to investigate the largest range of physics possible. Having two independently designed detectors is vital for cross-confirmation of any new discoveries made.
Two medium-size experiments, ALICE and LHCb, have specialised detectors for analysing the LHC collisions in relation to specific phenomena.
Two further experiments, TOTEM and LHCf, are much smaller in size. They are designed to focus on "forward particles" (protons or heavy ions). These are particles that just brush past each other as the beams collide, rather than meeting head-on.

Worldwide LHC Computing Grid

The Large Hadron Collider will produce roughly 15 petabytes (15 million gigabytes) of data annually – enough to fill more than 1.7 million dual-layer DVDs a year!
Thousands of scientists around the world want to access and analyse this data, so CERN is collaborating with institutions in 34 different countries to operate a distributed computing and data storage infrastructure: the Worldwide LHC Computing Grid (WLCG).
