What is a Collider? What is a Collider? What does it do?

Today, high-energy accelerators are huge, such as Fermillab's 1,000 billion electron volt proton synchrotron, which has a circular orbit of more than 6,000 meters. If the energy is to continue to increase, the footprint of the accelerator will inevitably increase significantly. For example, an accelerator with an energy of 100 billion electron volts will be made as big as the Earth.

Of course, this is not possible. So what to do? It's a good idea to build a collider.

A collider, as the name suggests, is a machine that achieves a head-to-head collision of two beams of high-energy particles. We know that if a beam of high-energy particles is used to bombard a stationary target, only a small part of the energy of the high-energy particles is effective for interaction, that is, the effective energy is very low, and the effective energy of two beams of high-energy particles colliding head-to-head will be much greater. For example:

Two beams of 30 billion electron volts collide head-tohead, which is equivalent to one beam of 19 trillion electron volts to bombard stationary protons; Two beams of 20 billion electron volts collide head-on, which is equivalent to a beam of 1600 trillion electron volts bombarding a stationary electron. Obviously, from an energy point of view, the collider is much superior to ordinary high-energy accelerators, so the collider is one of the main means of conducting "ultra-high-energy" experiments.

Currently, the world's highest-energy collider is the electron positron collider (PETRA) at the Electron Synchrotron Center in Hamburg, Germany. Construction began in January 1976 and was officially completed in April 1979. At present, the energy has reached 19 gev by 9 gev, which is equivalent to about 1,444 trillion electron volts of the energy of an ordinary high-energy accelerator.

CERN's ISR is currently the world's largest proton collider. The energy can reach, about 100 million electron volts equivalent to the energy of an ordinary high-energy accelerator.

The highest-energy collider under construction, planning, and brewing is the Electron Positron Collider (LEP), which began construction at CERN on September 13, 1983, with an estimated energy of 200 GEV times 00 GEV, which is equivalent to an ordinary high-energy accelerator with an energy of 100 billion electron volts. After the completion of the third phase of the UNK accelerator planned by the Soviet Union, a proton collision experiment with an energy of 3,000 GEV by 000 GEV can be carried out, which is about one hundred billion electron volts equivalent to the energy of an ordinary high-energy accelerator.

At present, the US high-energy physics community is considering building a proton collider of about 20,000 gev by 20,000 gev, which is equivalent to the energy of an ordinary high-energy accelerator and can reach as high as 8.5 billion electron volts.

With the collider, extremely high energy can be obtained. However, on the collider, there are only a limited number of experiments carried out, so it and the high-energy accelerator should complement each other. The collider is nothing more than a complement to a high-energy accelerator, not a replacement.

What exactly is a collider? Why is Yang Zhenning against building it?

The collider is an instrument for scientific research. The collider's ability to measure the flow of high-energy charged particles is very useful in scientific research.

A collider is a device used to study particles; It is mainly used to collide two particles and make them shatter, so as to study.

This refers to a kind of particle accelerator, the main function is to display light points on the screen, computer screens, TV screens will be used.

The larger ones are as follows:

Europe: LHC (Large Hadron Collider, mainly located in Switzerland and France, currently the largest Hadron Collider in the world).

Japan: ILC (International Linear Accelerator. Building. ）

United States: There are already many large accelerators, such as Fermilab, Stanford linear accelerator, etc.

The Superconducting Super Collider (SSC) is the largest scientific research construction in history, but it was abandoned by Liang because the cost of rubber was too high to be built.

China: BEPC (Beijing Positron Collider), CEPC (Circular Electron Positron Collider). Under construction, it will be the largest collider in the world when completed.

At present, there are mainly the following large colliders in the world:

1.CERN's Large Hadron Collider (LHC), located on the border between Switzerland and France, is currently the world's largest and most energetic particle accelerator and impact experiment facility.

2.The Super-Symmetric Particle Accelerator (SUPERKEKB) of the Japan High Energy Accelerator Research Agency (KEK), located in Tsukuba, Japan, is currently the world's largest source roller capable of producing the largest number of proton antiproton collision events.

3.The energy-enhanced proton collider (Tevatron) at the Fermilab National Accelerator Laboratory in the United States, once the world's highest-energy particle accelerator, ceased operation in 2011.

4.The Beijing Positron Collider (BEPC) at the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences is currently the only collider in China, and in 2008 it was upgraded to the Beijing Positron Collider Special Project (BEPCII), becoming one of the most advanced particle accelerators in Asia.

These are the major call-up machines in the world at present. These colliders have played an important role in the study of the structure of elementary particles and the evolution of the universe in the microscopic field.

1. Its main function is to accumulate and accelerate the flow of two particles injected by the pre-accelerator one after another, and make them collide in the opposite direction of motion when the beam intensity and energy reach a certain intensity, so as to produce a high enough interaction reaction rate, so as to facilitate measurement.

2. The collider is an instrument for measuring high-energy particle experiments, with the purpose of discovering 'new physics-new particles', including field energy efficiency particles, supersymmetric particles, super-dimensional quanta, etc.

3. At the same time, the collider is also a law of 'particle mechanism', which is a new physics-new particle exploration beyond the 'particle standard model', and there are institutional mechanisms of 'positron and negative electron colliders' and 'unconventional coupling of neutrons and electrons' in nature. Therefore, the collider has a very important construction significance in high-energy particle physics-condensed-particle astrophysics.

1.No, 2Nothing good, 3.Ordinary people can't do it, and as for the results of their research will benefit mankind, it is a matter of at least 10 years or even decades, just like Einstein's theory of relativity 100 years ago, and the benefit of mankind is only a matter of recent decades.

The collider is a device developed on the basis of a high-energy synchrotron, and its main function is to accumulate and accelerate the flow of two particles injected by the pre-accelerator one after another, and make them collide in opposite motion when the beam intensity and energy reach a certain intensity, so as to produce a high enough interaction reaction rate to facilitate measurement.

The collider is an instrument for measuring high-energy particle experiments, with the aim of discovering new physics-new particles, including field energy efficiency particles, supersymmetric particles, super-dimensional quanta, etc. At the same time, the collider is also a law of particle mechanism, which is beyond the standard model of particles, and there is an unconventional coupling mechanism of positive and negative electrons colliders and neutrons and electrons in nature. Therefore, the collider has a very important construction significance in dismantling high-energy particle physics-condensed matter-particle astrophysics.
