Particle Collider Presenter? Which country has a particle collider

Sina Science and Technology News At around 15:30 Beijing time today, CERN introduced the first batch of protons into the annular tunnel of the Large Hadron Collider, officially launching the world's largest particle collider.

In today's accelerated test, the proton beams will move in an anticlockwise direction, and if the test is successful, scientists may inject another clockwise beam of protons a month later and then have them hit head-on.

As the first step in a long-term experiment, the beams of subatomic particles will be accelerated to nearly the speed of light and then collide, with the impact briefly generating temperatures of up to 100,000 times the temperature of the sun in a tiny space. Analysts will keep a close eye on the entire impact process in search of elementary particles. Peter Jenni, a spokesman for the Atlas (Atlas Instrumentation Experiment, hereinafter referred to as the Atlas) spokesman, said:

We will enter a whole new field of physics. The 10th is a very important milestone. "The Atlas is one of four huge laboratories installed on the ring tunnel.

Detectors attached around the ring tunnel will monitor the impact process.

In a 10-hour experiment, the particle beam could travel more than 10 billion kilometers (6 billion miles), enough to make a round trip between Earth and Neptune. At maximum intensity, each beam holds the equivalent of a car traveling at 1,600 kilometers (1,000 miles) per hour. The Large Hadron Collider will consume 12

Named after the British physicist Peter Higgs.

You mean the principle or something.

The larger ones are as follows:

Europe: LHC (Large Hadron Collider.

Mainly located in Switzerland and France, it is currently the world's largest hadron collider).

Japan: ILC (International Linear Accelerator.

Building. United States: There are already a number of large accelerators, such as Fermilab and Stanford.

linear accelerators and much more. The Superconducting Super Collider (SSC) is the largest scientific research project in history, but it was abandoned because it was too expensive to build.

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

Function: 1. Make the accelerated particles collide and restore the universe as much as possible.

the environment in which it arises;

2. Do various particle experiments.

Workflow. The protons in the two collision accelerometers each have an energy of 7 tev (megaelectron volts) for a total impact energy of 14 tev. The time for each proton to orbit the entire storage ring is 89 microseconds.

microsecond）。

Because of the synchrotron's scattered nature, the particles in the accelerator tube are in the form of bunches rather than a continuous stream of particles. The entire storage ring will have 2,800 particle clusters.

Equipment structure:

It was built by universities and laboratories belonging to more than 2,000 physicists from 34 countries.

The LHC consists of a circular tunnel with a circumference of 27 km, located between 50 and 150 meters underground due to the local topography. This is a reuse of the tunnels previously used by the large electron positron accelerator (LEP).

The tunnel itself is three meters in diameter, on the same plane, and runs through the Swiss-French border, with most of the main part in France. Although the tunnel itself is underground, there are many ground facilities such as cooling compressors, ventilation equipment, control motor equipment, and freezing tanks built on top of it.

The function of the particle collider is to accumulate and accelerate the flow of two particles injected by the pre-accelerator in succession, and when the beam intensity and energy are fixed, they collide in a state of opposite motion, so as to produce a sufficiently high interaction response rate for easy measurement.

When bombarding quiescent palladium (particles) with high-energy particle boots, only the energy in the wide leakage excitation of the centroid system is the effective energy of the particle interaction, which accounts for only a part of the total energy of the particles in the laboratory system. If the energy of the particle hitting the target is e, then the centroid energy acting on the same particle in the target is about e.

The Particle Collider is a high-energy physics device that accelerates the collision of microscopic particles. It helps physicists explore, discover, and quantify particles. Its most basic function is to accumulate and accelerate the stream of particles in a high-energy accelerator, and when they reach a certain intensity and energy, they collide to produce a sufficiently high reaction energy as expected by the experiment.

As a research facility for basic disciplines, the collider is widely used in the field of high-energy physics. Today we are going to talk about the role of particle colliders in the astrophysics of exploring the origin of matter in the universe.

If the particle collider can reveal the true nature of matter, it can be found out how the most basic matter is produced in the big **. On the contrary, if the experiment shows that it is impossible to produce the most basic substance in the big **, then the big ** theory cannot be established.

Modern particle colliders are very large. For example, the Large Hadron Collider (LHC) is currently the world's largest and most energetic particle accelerator at the Joint European Centre for Nuclear Physics (CERN) in Switzerland. Its 17-mile (27-kilometer) underground tunnel acceleration ring was built by universities and laboratories in 34 countries.

The particle collider can accelerate millions of particles to the speed of light, and the stream of particles soars 11,245 times per second in the 27-kilometer-circumference acceleration ring. The process of particle collision discovered by the experiment is a particle collision spectacle at the forefront of exploring the origin of the universe. Other important experimental results include b meson, w+ -, and z.

and other particles.

First, in particle collision experiments, scientists accurately measured how much energy was released from the collision between an electron and an atom. It shows that energy and mass can be converted into each other in a certain way, and the mass increased by particles close to the speed of light is also measured. The experimental results once again verify the accuracy of Einstein's special theory of relativity, i.e. e=mc 2.

Mass and energy can be converted into each other.

Secondly, on the high-power collider, scientists have been able to briefly reach the original temperature within 1 second, and the fact of the collision at this moment is that at extremely high temperatures, the particle trail after the collision has a very short lag time difference, that is, pure energy is generated after the collision, and then the particle trail is generated in these energies. This is where matter comes into being in the first place.

The explanation obtained by this experiment is consistent with all other known evidence for the existence of a large **, as well as with the mathematical model that the universe began with a large **. Once again, the big ** theory is supported by experimental evidence.

The results of repeated particle collision experiments by the research team have shown that the particle collider has been unmistakably observed and recorded that particles can be turned into energy, and energy can also be turned into particles. Compared to all matter, energy is the most basic.

And the total amount of surplus particles produced in the large ** forms the entire matter of the universe today.

That's what the particle collider gives us. In this sense, the universe does not "come out of nothing", it comes from energy that is both untouchable and intangible.

Two units. In 2008, the world's first and largest Hadron Collider was built at the foot of Mount Jura on the border between Switzerland and France. Buried 100 meters underground, the device is a circular accelerator with a total length of 27 kilometers.

In 2004, the Beijing Positron Collider Major Renovation Project (BEPCII) project was launched, and a new Beijing spectrometer (BES) matching the high brightness of BEPCII was built by using a double storage ring and a large cross-angle collision scheme. So far, there have been two.

Finally, the collision brightness is 95 times higher than that of BEPC, and the brightness of the collider is the number of particles per square centimeter per second that two bundles collide.

The increased brightness means that the number of paraplastic mold-proton reactions that occur under the same conditions and at the same time increases, thus providing more experimental data for physical research. In 2016, BEPCII's Collision Brightness was reached under energy, and the victory reached the acceptance index of brightness.

The development of the particle collider is as follows:

After the completion of the Beijing Positron Collider, Chinese high-energy physicists have obtained a number of important achievements in high-energy physics, such as accurate measurement of lepton mass, r-value measurement, and discovery of new resonance states of particles.

On the internationally authoritative particle data sheet, more than 500 data are now from the Beijing Positron Collider. Since then, China has occupied an international leading position in the field of international high-energy physics.

The Beijing Positron Collider is China's first large-scale scientific facility, which not only enables China to occupy a place in the field of high-energy physics in the world, but also promotes China's development in high-tech fields such as accelerators, detectors, the Internet, and high-performance computing. <>

The role of the particle collider is to cut microscopic particles, and its principle is quantum mechanics.

Our world is made up of countless microscopic particles, such as molecules, atoms, and quarks. Scientists have long wondered what the inside of these microscopic particles that make up us look like. Therefore, by chance, the particle collider was created through the principle of quantum mechanics, which is a machine that sets high-energy particles to collide with each other, and in layman's terms, it is a scalpel that can cut microscopic particles.

The predecessor of the particle collider was the synchrotron, which is very similar in shape to a ring, exerting more and more energy on the particle through a magnetic field, bringing it close to the speed of light before hitting the target particle. There are three main steps, which are accumulation, acceleration, and collision. In fact, it is very difficult to control a particle collision, so a large number of particle beams are generally used to collide to increase the frequency of particle collisions.

When particles collide, they must have a lot of energy to break apart, and if the energy is not enough, the colliding particles will combine to form new particles. This is the reason for the outer ring of the particle collider, which can increase the path of acceleration of the particles, giving the particles greater acceleration to gain more energy.

The invention of the particle collider has brought many new chapters to the scientific community, many special microscopic particles are found in the particle collider, China's current particle collider was born in Beijing in 1990, is a positron and negative electron collider, the Chinese Ding Zhaozhong also won the Nobel Prize for the discovery of brand-new particles on the electron collider.

Although the particle collider is very good, there is no idea of continuing to study a large particle collider in our country at present, and scientists have said that even if it is successfully developed, it will have no concrete significance in the next 50 years. Therefore, the particle collider is still a thing of the future, and I hope that one day in the future, there will be a breakthrough in physics, so that the dust particle collider can contribute to mankind again.

The function of the particle collider is mainly to accumulate and accelerate the particle flow in the front pole accelerator, so that the particle flow can operate to a certain intensity and energy, and then the high energy generated by the collision is carried out. In addition, the collider is actually a microscope, which generates energy by observing particles and running them at high speeds.

The role is to help human beings better explore the origin of the universe and many other issues. The principle is to use the interaction between the electric field and the magnetic field to accelerate the positive and negative ions to nearly the speed of light to make an impact.

The effect is to accumulate and accelerate the particle flow motion. The principle is to cause two streams of particles to collide with each other in relative motion, knock them apart or form new particles.

It's about figuring out the limits of what humans can detect.
