"Teacher Ding, this sparrow is so fragrant, it's much better than roasting it over fire."

Xiong Cheng, the number one disciple who followed Ding Biyun into the mountain, picked up a roasted sparrow that was still bubbling out with a wooden stick, and he smelled the aroma from afar.

The person in charge of the antenna array construction next to him also approached and commented matter-of-factly:

"Except for the hair on one side of the belly because of the heat accumulation, the rest of the place is really heated evenly, inside and outside at the same time, if you control the heat again, how tender the meat is.

I used to sell this in my hometown, but it tastes good if it is not done well, so it tastes right. ”

Ding Biyun, who was standing next to the flat panel array antenna, had black lines on his face, wanting to kick the dead sparrow and was afraid of getting oil, so he could only hum twice in the end.

The first space-based power transfer test – 50% success.

Ten minutes ago, the Chiwu-1 satellite in the sky accurately limited the microwave beam to the antenna array, and the solar energy from outer space reached the ground at a distance of 0.12 light seconds, and then was efficiently converted into electricity by the receiving coil.

In a period of up to 10 minutes, the average power generation of Chiwu-1 was 451 kilowatts, the transmission power was 447 kilowatts, and the average ground received and converted power was 375.5 kilowatts, with a transmission conversion rate of 84%.

The efficiency is a lot lower than expected, 7.5% less electricity, but it's acceptable and still very good.

The temperature of the receiving antenna is also okay, and the temperature of the receiving antenna only rises to 24 degrees Celsius when the outdoor temperature is 17 degrees Celsius, and the temperature control is quite good.

However, after a while, the control room suddenly found that the efficiency was slightly reduced, and then the outdoor infrared detection station sent an early warning, saying that a temperature anomaly was found in the antenna, and the control room immediately turned off the microwave transmission antenna of Chiwu No. 1 for safety reasons, and then hurriedly went to check.

In the end, it was found that the sparrow, which I don't know where, had fallen on the antenna, and was subjected to microwave scorching with an average power of 447 kilowatts.

The poor sparrow first lost its ability to struggle due to the huge amount of microwave radiation, and then its entire body began to be evenly heated from the inside out.

But just this heating power is okay, after 36,000 kilometers of scattering 447 kilowatts of power distribution range reached 12,500 square meters, the power per square meter is only 36 watts, and it can't be burned to death.

However, the unfortunate thing is that the place where it lies is exactly the receiving antenna near the center point, and the antenna array will concentrate most of the microwaves in a small area through the reflective surface, so the heat from other places continues to accumulate at the contact point, and the accumulated heat rises rapidly, and it begins to be heated from the side that lies down, and when Ding Biyun and others arrived, it was almost cooked......

This can only be regarded as a small accident, the transmission test itself is quite successful, that is, the transmission efficiency is not known why it is lower than expected, but the efficiency of 84% is actually ready for practical use.

"The trees here are too dense, and at the beginning, we only took into account the small impact of clutter and the Qinling Mountains that were recently elected in Chang'an, so I am afraid that it will be very unfavorable to the ecological environment in the future.

At least cut down all the trees around to prevent small animals from disturbing, and move to an open area in the future. ”

Listening to his mentor's words, Xiong Cheng's face fell:

"Teacher Ding, we won't go to the Great Gobi."

"Not really." Ding Biyun grabbed his hair, although theoretically the conditions in the Gobi Desert are good, he doesn't want to go to the Gobi Desert.

"In fact, in the future, the antenna can be made into a semi-enclosed parabola, which can not only concentrate microwaves but also prevent interference, but the construction cost is too high, and I don't need it during the test, so I still have to contact and cut down trees."

You immediately contact Xinyuan Company and the Shuchuan government, tell them that the experiment was very successful, and quickly transfer the remaining half of the second batch of funds. In addition, to urge the company's upgraded solar cells, it must be mass-produced by the end of this year, and poor cost control is the trouble. ”

……

Capital.

Frank Yang walked on crutches on the campus of Tsinghua University, and when passing students and teachers passed by, he greeted him warmly as usual, and he nodded politely in response.

But as soon as the students walked past him, they would gather together and whisper, and they would look at him from time to time.

The reason why this is so is because a major incident has happened in the past few days, a reporter from China News Service reported: Frank Yang, who once resolutely opposed the construction of accelerators, is now vigorously in favor of building high-energy accelerators!

There are all the evidence in black and white, audio and images, and it is not a small or medium-sized accelerator, but a super ring proton accelerator with a circumference of more than 100 kilometers will be built to charge the last barrier of cutting-edge physics!

When Frank Young returned to China, he believed that the national strength at that time should not be used to build accelerators that were useless for people's livelihood, and he really did this.

Later, in the 10s, some people began to emphasize the importance of basic science, but Frank Young did not speak, and always felt that the time was not ripe.

He opposed the accelerator as soon as he returned to China in 1970 and has been against it since the 80s, but the Institute of High Energy Physics resisted the pressure to become BEPC.

In 2012, when Wu Yunfeng said that he wanted to engage in CEPC and the 100-kilometer positron collider, Frank Young's attitude remained the same.

Although there is no official news yet, there are rumors that the new proton accelerator will be named "TEPA (Three-hundred trillion Electron volts Proton Accelerator)", which means 300Tev proton accelerator.

The grapevine also reported that the TEPA project will be completed in two phases, with an investment of 24 billion yuan in the first phase and 87 billion yuan in the second phase, with a total cost of about 110 billion yuan to build a 140-kilometer circumference of the accelerator, which is more than five times larger than the LHC.

In addition, a new National High Energy Physics Research Center will be built together with TEPA, with an investment of about 7 billion yuan, to further improve the domestic basic scientific research capacity to the international leading level.

So by the time the boss got on the plane back to Beijing, the popular news headline had become:

"Frank Young proposes to spend $200 billion to build an accelerator."

"More than 170 cutting-edge physicists, including Stephen Hawking, and more than 1,000 domestic scientists have jointly endorsed the launch of the TEPA program, and many of the world's top universities have also expressed their support."

"Lin Ju: Invest 10 billion yuan in basic science!"

In an interview, Liu Cixin denied the feasibility of building a superaccelerator along the equator, saying that it was just a science fiction idea, and that scientists in reality are even greater.

"Nobel laureate François Engler: If TEPA is built and willing to go to China for research, TEPA is a great breakthrough."

"More than 80% of the 75 million participants voted in favor of donating money to build the accelerator, and the importance of basic science is deeply rooted in the hearts of the people."

“……”

As soon as the plane landed, the superiors began to shake people, not the high-energy institute, but the Ministry of Finance.
