The preparation for this experiment is much more complicated than before. The requirements for temperature adjustment and detection are higher, so the experimental design, process, and control must be more precise.
In addition, the experiment used an iron-based alloy superconductor, and the superconducting excitation temperature is only about 20K (Kelvin). It is necessary to create ultra-low temperatures below minus 250°C, which is several times more difficult.
"It's best to have a large device that controls the temperature accurately."
Xiang Qiansheng said, "To conduct this experiment with our current equipment, the experimental design will be very complicated and the accuracy is not enough."
Wang Hao thought for a while and asked, "The accuracy is almost acceptable. I just want to see the phenomenon."
He Yi sounded a little distressed, "This experiment will probably cost a lot of money."
"Don't worry about the funding." Wang Hao did not consider the funding issue. As long as it is within the normal cost range, it is acceptable. Even if it costs more, a few million for one experiment is enough.
Xiang Qiansheng thought for a while and then suggested, "Professor Wang, are we going to do experiments like this in the future? If we do a lot, I still recommend purchasing a large-scale equipment that can accurately control the temperature."
Wang Hao asked, "How much does it cost to buy such a piece of equipment?"
"Money is not the key."
Xiang Qiansheng said, "This kind of equipment is imported and ordered from a fixed manufacturer. It takes a long time from ordering to manufacturing, transportation and debugging. This kind of equipment can be delivered in one year, which is already very fast." Soon."
He continued, "If it is used a lot in the future, we can purchase it from other laboratories. The Superconducting Laboratory has an idle temperature control equipment, and it has been idle for more than two years. Their projects cannot use it temporarily."
"How much does it cost?" He Yi immediately asked. It is good to buy second-hand top-notch scientific research equipment, but the main reason is that the price of cutting-edge equipment is too high and ordinary laboratories cannot afford it.
"It will cost more than 30 million."
Xiang Qiansheng thought for a moment and gave a figure, then explained, "The introduction of that equipment cost 60 million. Although it has been used for many years, it only cost 30 million, and the Superconducting Laboratory is not willing to sell it. "
Top-notch scientific research equipment is not an ordinary electronic product.
The market for this kind of cutting-edge equipment is small, and only large laboratories will buy it, but again, it is difficult to buy it.
Wang Hao nodded and said, "Let's prepare this experiment first. If the results are in line with expectations, we will then consider purchasing new equipment."
After the meeting ended, everyone in the laboratory became busy.
This is a large experiment.
It took more than a week to prepare for the experiment. Without purchasing new equipment or materials, every part of the experimental device was built by hand, and even the circuits inside were connected one by one.
After everything was ready, everyone gathered in the operation room and prepared to officially start the experiment.
Everyone's face was filled with tension and anticipation.
This is a very large experiment, not because of how large the scale is, but because the requirements for the experiment are too high and the corresponding costs are also very high. The total cost of the experiment is more than five million.
The previous experiments they conducted had a maximum cost of only 600,000 or 700,000.
In addition, the goal of the experiment is also very interesting. It is hoped to detect the AC gravity field phenomenon before the superconducting state is excited.
"If the superconducting state is not excited, will an AC gravity field be produced?"
"This is what Professor Wang said. It should be okay, right? I don't believe anyone, but I also believe Professor Wang."
"But it still sounds unreliable."
"If the AC gravity field can be detected without exciting the superconducting state, doesn't it mean that it is possible to activate the AC gravity field at room temperature and normal conductivity?"
"Now we are creating ultra-low temperatures, are you thinking too far ahead?"
Many people were discussing in low voices.
They were indeed very curious about the experiment, as were Liu Yunli and the other three. They felt as if they were about to witness a miracle.
People in the physics laboratory have great trust in Wang Hao, and it can even be said that they are fanatical. They have not reached this level yet, and they still feel that it is impossible to achieve anti-gravity in a non-superconducting state.
Wang Hao stood in front of the experimental equipment, stared at it for a long time with his lips pursed, and then waved his hand, "Let's get started."
Then he stepped aside and watched.
Although the experiment is very expensive and requires higher detection accuracy, the experimental process is no different from the original one.
The experiment is to continuously lower the temperature after power is turned on. After it drops to minus 150°C, the speed begins to slow down.
When it drops below minus 200°C, the rate of decrease becomes even slower, and the value also drops a little bit. The superconducting temperature of the iron-based superconductor used in the experiment is minus 259°C.
When the temperature reached minus 250 degrees Celsius, everyone looked carefully at the logo - ultra-thin balloon.
Several ultra-thin balloons are suspended directly above the device. The average density of the balloons is almost the same as that of air. Because the top and sides are isolated by glass covers, there is no air flow inside, and the balloons will not rise.
The temperature is still slowly dropping.
-
251℃.
-
252℃……
When it reached '-253°C', the balloon in the glass cover suddenly slowly rose upwards.
Although it only rose a little, the operation still caused a burst of exclamation, because the temperature has not yet reached the critical line of superconductivity.
The temperature continues to drop.
-
253℃.
Several balloons have been attached to the top of the glass cover. Other detection equipment has also changed its values. The pointer that detects the AC gravity field value has also deflected slightly.
Everyone was very excited, but everyone held their breath.
The experiment continues.
The final temperature reached minus 259°C. When the superconducting state was activated, the detection pointer suddenly deflected significantly.
But it's no longer important.
"That's it!"
Wang Hao's voice was also slightly excited. The theory he studied was verified again, which showed that his research direction and conclusions were correct.
The people participating in the experiment are still carefully recording the data.
Others couldn't help but excitedly discuss, "Is this a brand new discovery?"
"It turns out that stimulating an AC gravity field does not necessarily have to be in a superconducting state. Ordinary conductive states are also possible..."
"It may also be that in the ordinary conductive state, the AC gravity field is so small that it cannot be detected? It is completely covered by the electromagnetic field?"
"The AC gravity field may also be related to the electromagnetic field?"
"Anyway, this is definitely a big discovery! A super big discovery!"
Liu Yunli, Ruan Weiping and Xue Chang were also very shocked. They also knew that they were definitely making a big discovery in front of them.
They are only technically studying the AC gravity field, but no matter how much they study technically, it is impossible to make such a discovery.
The three of them were silent together.
Xue Chang said, "So I have always felt that our research is meaningless."
"It's better to move here quickly!"
"With the help of Professor Wang's theoretical research, we can find the direction of improvement in technology..."
Ruan Weiping pursed his lips and said, "You can apply for the move here first, but I think it's more important that we study Wang Hao's annihilation and topology theory."
"If we don't understand this, we'll never catch up."
Liu Yunli and Xue Chang nodded together. They had not paid attention to the 'annihilation topology theory' before, but now they finally discovered that the 'difficult to understand' theory mentioned by Wang Hao was the most important.
If they cannot understand the basic theory, they can only follow and watch, and it is impossible to truly participate in the research.
…
After new discoveries are made, the laboratory still summarizes data and summarizes experiments.
Wang Hao began to do further research. He encountered a bottleneck in his topological research on microscopic morphology within conductors.
But soon, good news came.
Lin Bohan officially resigned and came to Xihai University, signed an agreement to become an associate researcher at the Mason Number Laboratory, and also joined the exchange gravity research project of the Physics Laboratory.
Lin Bohan's resignation was not easy, mainly because the Mathematical Sciences Center attached great importance to him.
