Where does the accelerating energy of the particle accelerator come from?

In the 20 years from the 30s to the second half of the 50s of the 20th century, the energy of the accelerator increased by hundreds to thousands of times. This is because elementary particles are to be discovered. In addition to looking for cosmic rays, we have to go inside the nucleus.

There is a very strong force inside the nucleus, i.e., the nuclear force that holds the elementary particles together, so it takes a lot of energy to study the elementary particles. As the energy of the accelerator increases, so does the number of elementary particles found in the laboratory.

The particle accelerator is already smaller than a large machine factory, its electricity consumption is equivalent to that of a medium-sized city, and the staff can reach thousands of people. However, although the energy of today's particle accelerator is large enough, it is still far from meeting the requirements of exploring the mysteries of the atom, so as people explore the mysteries of the atom, the particle accelerator will continue to improve.

So far, the highest energy of the particle accelerator has been generated by the European Large Hadron Collider (LHC). Two beams of protons with energy collide with each other, with an energy of up to 7 tEV.

What kind of exploration process has human beings gone through to understand the microcosm? Why do we need large-scale scientific devices to study the microscopic composition of matter? Ye Minghan, academician of the Chinese Academy of Engineering and academic director of the China Advanced Science and Technology Center, will introduce you to the particle accelerator, an important tool for human beings to explore the microscopic world of matter.

The electric field does work on the particles whose initial position is on one side of the plate" Here is the energy**.

In this process, the electric field does positive work on the particle, and correspondingly, it can be considered that the particle does negative work on the electric field, so the energy of the electric field decreases and needs to be supplemented by the outside world.

Each time the electric field is reversed, the electric field does positive work on the particle, so the velocity of the particle gradually increases, while the electric field continuously consumes energy and is replenished by the outside world to maintain its electric potential.

In fact, energy is also required to switch the direction of the electric field, but it does not act directly on the particles.

Energy is certainly required to maintain the magnetic field, but again, it does not act directly on the particles.

for follow-up.

The potential energy of the electric field will definitely decrease after doing work on the particle, but because the work done is too different from the potential energy, Ji Xiaoyou will not reflect it, and the electric field will also be supplemented by the external circuit, 1, the energy of the electric field is determined by the potential difference between the two point poles, with the work done on the particles, the potential difference between the two ends will decrease (energy conservation), and the external power supply will continue to make up for the decrease of the potential difference, so that it is maintained at the constant (value) laughing level of the TV difference, so, Taken together, the energy obtained by the charged particle is actually part of the energy provided by the external circuit (because there is a loss, it will not be 100% converted).

That's it for a short time, if you want to calculate, you can calculate it with the help of a simple two-pole plate capacitor as an external electric field...1. There must be a magnetic field.

1: Conversion of electricity into magnetic field, that is, electrical energy into magnetic energy, in which the energy of the accelerated particles of the electromagnetic particle accelerator comes from the electrical energy that provides the magnetic field.

2: Plates or magnetic poles, in which the energy of the particles accelerated by the electromagnetic particle accelerator comes from the plates or magnetic poles.

If you think about it, the magnetic field provided by the plates or poles is also time-limited, and the magnetic field will weaken over time, that is, the energy will also become smaller,..0, the energy of the accelerated particles of the electromagnetic particle accelerator comes from **.

The electric field does work on the particles whose initial position is located on one side of the plate, and the particles accelerate their motion to shoot out the electric field, enter the magnetic field, and return to the original electric field plate after half a turn and half a turn, although the position has changed, the electric potential energy is the same as at the beginning, and the kinetic energy has increasedLike this, circle by circle, the energy of the particles is getting bigger and bigger, and this energy comes from?

Let's reverse the electric field without consuming energy.

It doesn't seem to take energy to maintain an electric or magnetic field, just put the plates or poles there (at least theoretically).

What energy of the electric field decreases when the electric field does positive work on a particle? Is electric potential energy?

Correspondingly, it can be said that the particle does negative work on the electric field", do you mean that the particle does negative work on the "object" of the electric field?

I mainly don't understand how the energy of an electric field can be understood in addition to electric potential energy. That is to say, the charge distribution before and after the plate does work on the particle, that is, the electric field does not change; Then the particles return to the same electric potential after turning in circles, and the energy of "electricity" should not change.
