What is the Large Hadron Collider?

The Large Hadron Collider is a "new physics" mechanism device for particle physics scientists to explore new particles and microscopic quantified particles. It is a high-energy physics device that accelerates protons to collide. The English name is LHC (Large Hadron Collider) .

Large Hadron Collider

Purpose of the construction process and exploring microscopic particles

LHC is an international cooperation project, jointly funded by universities and laboratories owned by more than 2,000 physicists in 34 countries.

The LHC contains a 27-kilometre circular tunnel located between 50 and 150 meters underground due to local terrain. This is the previous large electron positron

In 1994, after the Large Hadron Collider project was approved,

It officially started operation at 15:30 on September 10, 2008.

In two colliding acceleration tubes

CERN launched the Large Hadron Collider (LHC) on September 10, 2008. The world's largest machine is expected to unravel the mysteries of the origin of the universe, including five major mysteries.

Over the past few decades, physicists have deepened their understanding of the basic particles and their interactions that make up the universe in detail. Deepening of understanding

All six experiments using the Large Hadron Collider (LHC) will be completed under the mode of international cooperation. These experiments bring together scientists from research institutions around the world to witness an exciting moment. Each experiment is completely different, and it is determined by the uniqueness of the particle detectors it uses. Two large-scale experiments-ATLAS (English abbreviation for toroidal instrument experiment, hereinafter referred to as ATLAS) and

The LHC construction funding was originally a 2.6 billion Swiss francs approved in 1995, and another 210 million Swiss francs was used for experiments. However, funding was overrun. A major review in 2001 was expected to require an additional 480 million Swiss francs in the construction of the accelerator and an expenditure of 50 million Swiss francs in experimental operations. At the same time, due to the reduction of CERN's annual budget, the completion date of the LHC was postponed from 2005 to April 2007 to pay with more annual budget. The increase of 180 million Swiss francs is in the manufacture of superconducting magnets. In addition, there are still engineering difficulties when constructing underground caves that house CMS. The expected total construction is approximately $ 8 billion.

The Large Hadron Collider accelerates two beams of protons to an extremely high energy state of 14TeV (14 trillion electron volts) and collides them. Its energy state can be related to

The largest machine in the world

In July 2014, the Beijing Institute of High Energy Physics in China was preparing a toroidal particle collider with twice the LHC.

The perimeter of the collider to be built in China has reached 52 kilometers and the collision energy is as high as 70 TeV. According to the plan, China's collider will only target electrons in the early stage, and the collision energy will only have 240 GeV energy, while in the later stage, it will gradually open up enough horsepower for proton collision.

It is expected that China's collider will be put into use in 2028 and cost $ 3 billion. It is unclear whether this is a joint project with foreign counterparts. ^[7]
