Ronald Vigo stood in front of the busy construction site, pointed to the building under construction not far away and began to introduce the situation of the international thermonuclear fusion reactor, "The ITER device still follows the operating principle of the Tuokemark device, but the actual Yàn device we built is larger in scale and has a higher energy level!"

"That location will be where the heart of the ITER unit will be installed, the high-temperature deuterium-tritium plasma ring. Bigo's finger changed direction, "It contains 15 megaamperes of plasma current, 500,000 kilowatts of nuclear fusion reaction power, and releases up to 1,020 high-energy neutrons per second." The plasma ring is in a ring sleeve of a shielding cladding that will absorb 500,000 kilowatts of thermal power and all the neutrons produced by the fusion reaction. ”

"There is nothing new in the design principle! But such a large power is not comparable to our real device!" Someone in the Chinese delegation whispered his opinion.

"A mixture of a few milligrams of deuterium and tritium is packed into a small ball about a few millimeters in diameter, and then a laser beam or particle beam is evenly injected from the outside, and the inner layer of the sphere is squeezed inward. The gas in the ball is squeezed, the pressure rises, and the temperature also rises sharply, and when the temperature reaches the required ignition temperature, the gas in the ball explodes, producing a large amount of heat energy. Such explosions occur three or four times a second and continue on and on. Most of the existing controllable nuclear fusion devices use this method!" Some people were born to be harmonious, and when they said this, the representatives of Huaguo not only gave birth to a sense of pride, but the founder of this theory was none other than Mr. Wang Ganchang, a scientist of the older generation in Huaguo.

"Hey, the more we invest, the more hope we have of achieving results! Our country only allocates $1 billion a year to controlled nuclear fusion research, and we still have to distribute it to so many units! If this situation does not change, we will have to catch up with Mi Guo and ITER for a long time to come!" Academician Nie sighed and couldn't help but grumble. "At the end of last year, I approached the higher authorities many times to apply for funding, but the result was that there was still only that!"

"Yes, how can we do it without money!" This sentence caused a chorus of echoes from the scene, but Ma Yang showed a smile on the corner of his mouth at the edge of the crowd, it's not that the country hasn't invested a lot of money in this field, it's just that it hasn't been handed over to you!

"Don't talk about being practical! Without funds, it's not easy for us to recruit people. As soon as the Xihe plan came out, they robbed them of talents in both the superconducting field and the laser field! If you want me to say that space technology is important, without controlled nuclear fusion, there will be no fundamental development in space technology! Before he could be happy, the topic gradually developed in the direction that worried him.

"Mr. Bigo, may I ask what kind of device is being built over there!" Ma Yang was afraid that these people's words would make an inappropriate association with the ITER staff, so he quickly stepped forward to ask.

"That's a hoop superconducting magnet, which is capable of generating a strong hoop magnetic field of 5.3 Tesla, and is one of the key components of the device. The installation will cost $1.2 billion. Mr. Bigo didn't seem to notice the discussion of the Chinese scientists, and continued to introduce it to everyone, and when he said 1.2 billion US dollars, his tone revealed a sense of pride, in his opinion, except here and in the United States, I am afraid that no country in the world can come up with such a big hand, "The center of the ring is a huge superconducting coil barrel, and there are six large hoop superconducting coils on the outside of the hoop field coil, that is, the polar field coil. The role of the central solenoid and the polar field coil is to generate the plasma current and control the plasma shape. High-temperature deuterium-tritium plasma rings and hooped superconducting magnets are encased in a large dewar. It sits on the base and constitutes the body of the real yàn pile. ”

Mr. Vigo's fingers are pointing around the body. The names of one device after another and their basic parameters were announced, "Outside the main body are four 10 megawatt strong current particle accelerators, 10 megawatts of steady-state millimeter electromagnetic wave system, 20 megawatt radio frequency wave system and dozens of advanced plasma diagnostic measurement systems." The whole system also includes: large-scale power supply system, large-scale tritium plant, large-scale water supply (including deionized water) system, large-scale high-vacuum system, large-scale liquid nitrogen, liquid helium cryogenic system, etc. All possible adjustments and repairs in the ITER body are done by a person or a hand who controls the machine remotely. ”

"Gentlemen, the ITER device represents the world's highest level of research on controlled nuclear fusion, and it also uses state-of-the-art technology in several fields, such as large superconducting magnet technology. Medium-energy high-current accelerator technology, continuous, high-power millimeter wave technology, complex remote control technology, etc. After introducing the device, Mr. Bigo raised his chest, as if to say come and worship. Come and praise us French for their prowess!

Sure enough, as soon as his words fell, Academician Nie took the lead in applauding, and then the applause of the other Chinese delegates also rang out, and Mr. Bigo's chest stood higher in the applause.

"Iter is indeed a joint product of several major scientific and technological powers in the world! Both in scale and efficiency are much stronger than our current real devices! Even East may not be able to compare with the real energy heap we see now!" Academician Nie first sighed.

"Yes, our reactor is a toy compared to this one!" echoed a representative from another city in Shuzhong Province.

"According to the agreement we made, we can send staff here to conduct research, if only I could come here!"

Mr. Bigo laughed from ear to ear in the praise of everyone, and he looked at these people with admiration and admiration expressions in satisfaction, but when his gaze swept over Ma Yang, the smile suddenly froze; Ma Yang's face had a smile that was not easy to be noticed, this smile was not the happy smile of Academician Nie and others when they saw the heavy changes in their field of study, but a faint smile of disdain.

If it were an ordinary person, I am afraid that I would not be able to detect the meaning of his smile, but who made Monsieur Vigo a romantic Frenchman by nature, when he was young, he toppled countless beautiful figures on the banks of the Seine, and he was very sensitive to the information hidden behind those subtle expressions!

Ma Yang suddenly felt that something was wrong, and raised his head to meet Mr. Bigo's gaze, oh, could it be that he had discovered something wrong, right? Ma Yang hurriedly asked, "Mr. Bigo, what is the design goal of ITER?" (to be continued...... ）
