Large Hadron Collider – LHC, in general, the LHC refers to a machine that deserves to be labeled the “Largest” in the world made by human which is weighs more than 38,000 tons (thirty eight thousands). This machine is located 100 meters beneath the Swiss / French Border at Geneva which is runs for 27 km (16.5 mile) in a circulated tunnel but as an international project the LHC crosses continents and many international borders..
The LHC (Large Hadron Collider) is an International Project, in which the UK has a leading role in this project and has scientists and engineers working on all the main experiments. The LHC’s 27 km loop in a sense encircles the globe, because the LHC project is supported by an enormous international community of scientists and engineers. Working in multinational teams, at CERN and around the world, they are building and testing LHC equipment and software, participating in experiments and analyzing data.
However, the Collider is only one of three essential parts of the LHC project. The other two are:
- The Detectors: which sit in 4 huge chambers at points around the LHC tunnel.
- The GRID: which is a global network of computers and software essential to processing the data recorded by LHC’s detectors.
What will this Big Machine (LHC) do:
The LHC will allow scientists to probe deeper into the heart of matter and further back in time than has been possible using previous colliders. Researchers think that the Universe originated in the Big Bang (an unimaginably violent explosion) and since then the Universe has been cooling down and becoming less energetic. Very early in the cooling process the matter and forces that make up our world ‘condensed’ out of this ball of energy.
The LHC will produce tiny patches of very high energy by colliding together atomic particles that are travelling at very high speed. The more energy produced in the collisions the further back we can look towards the very high energies that existed early in the evolution of the Universe. Collisions in the LHC will have up to 7x the energy of those produced in previous machines; recreating energies and conditions that existed billionths of a second after the start of the Big Bang.
How does the LHC Work:
The LHC accelerates two beams of atomic particles in opposite directions around the 27km long Collider. When the particle beams reach their maximum speed the LHC allows them to ‘collide’ at 4 points on their circular journey. Thousands of new particles are produced when particles collide and detectors, placed around the collision points, allow scientists to identify these new particles by tracking their behavior.
The detectors are able to follow the millions of collisions and new particles produced every second and identify the distinctive behavior of interesting new particles from among the many thousands that are of little interest. As the energy produced in the collisions increases researchers are able to peer deeper into the fundamental structure of the Universe and further back in its history. In these extreme conditions unknown atomic particles may appear.
