European Large Hadron Collider

European Large Hadron Collider (Picture 1)

The Large Hadron Collider is a device for particle physics scientists to explore new particles and microscopically quantify particles. It is a high-energy physical device that accelerates the collision of protons. The European Large Hadron Collider is the world's largest and most energetic particle accelerator, with 7,000 scientists and engineers from around 80 countries. Built by 40 countries. It is a high-energy physical device that accelerates the collision of protons. It is a circular accelerator, buried 100 meters underground, and its ring tunnel is 27 kilometers long. It is located at the European Nuclear Research Center (also known as the European Particle Physics Laboratory) in Geneva, Switzerland, across France and Switzerland. border. On September 10, 2008, the collider was first launched for testing.

In order to save costs, physicists did not dig an expensive new tunnel to accommodate the new collider. Instead, they decided to remove the positive and negative electron accelerators that were originally placed at the European Nuclear Research Center and replaced them with large Hadron collisions. The 50,000 tons of equipment needed for the machine. When two proton beams move in the opposite direction in the circular tunnel, the powerful electric field causes their energy to increase dramatically. Each time these particles run, they gain more energy. To keep this high-energy proton beam running requires a very powerful magnetic field. Such a strong magnetic field is produced by a superconducting magnet cooled to near absolute zero. What physicists most want to build is a 30-kilometer-long machine that smashes electrons and positrons with at least 500 billion electron volts.

On November 8, 2010, scientists began to use the large European Hadron Collider on the Swiss-French border to create a small "big bang" that mimics the instantaneous process of the formation of the universe nearly 14 billion years ago. This is the first time the machine has used lead ions for collisions. Protons have been used in previous experiments. Lead ions and protons are collectively referred to as "hadrons", but the former are larger and heavier than the latter. Inside a circular orbit about 27 kilometers in length, the two bundles of lead ions travel in opposite directions, and each time they run, they gain more energy and speed. The high temperature generated by the collision is equivalent to 100,000 times the temperature of the sun core, that is, 10 trillion degrees. It is believed that this temperature is the temperature within a few millionths of a second after the Big Bang was born 13.7 billion years ago. At this temperature a "quark-gluon plasma" will be produced. The existing physics theory holds that within a few millionths of a second after the birth of the universe, there has been a substance called "quark-gluon plasma" in the universe. Scientists hope to solve the mystery of the formation of the universe through the mini "Big Bang" experiment.

In 2010, scientists involved in the Large Hadron Collider (LHC) project said they might be close to the Higgs boson. The Higgs boson is also known as the "God particle" and is said to play an important role in the formation of the universe after the Big Bang. On April 5, 2015, after about two years of downtime maintenance and upgrades, the European Large Hadron Collider was restarted and the second phase of operation was officially launched. It is hoped to explore the existence of supersymmetric particles of Higgs coupled particles. LHC can make a big step in human science and technology. For example, the formation and synthesis of antimatter will become possible. Finding antimatter and its synthetic methods will make it possible to solve our energy crisis and become the fuel of choice for space travel and interstellar travel. Antimatter has an incredible power, just a small amount of antimatter, and its energy with material annihilation can be compared with millions of tons of nuclear bombs.
