Nanke Dream Realm - City of Truth.

Institute of Geology of the Academy of Sciences.

Feng Qingyun, a geologist on duty in Nanke's Dream Realm, suddenly received an email.

When I opened it, it turned out to be a letter to assist in the research, mainly about the neutrino stream emission trajectory, the determination of the radioactive layer in the inner strata of the blue star, and the establishment of a ground emission point to avoid the radioactive bottom layer.

Hey? Top Secret?

When Feng Qingyun saw this, he was confused in his heart, what is there about neutrino and stratum radioactivity involving top secrets?

Moreover, the signatures of the invitation letter are Huang Mingzhe and Zhang Tingyu, and there is no one who does not know Huang Mingzhe in the domestic scientific community, and Zhang Tingyu is the deputy director of the Institute of High Energy.

This is the reason why Feng Qingyun is puzzled, he is engaged in physics and mathematics, how can he also play geology?

However, since it is a top secret, he is also very knowledgeable, and clicked to accept the invitation, and then his figure disappeared into the City of Truth.

Appears in a virtual space specially set up by Huang Mingzhe.

In this virtual space, there were already many people busy at this time, and Feng Qingyun also saw two other researchers from the Institute of Geology.

Seeing that the relevant personnel had arrived, Huang Mingzhe said straight to the point: "First of all, thank you very much for taking time out of your busy schedule, and then I will talk about the task ......."

He briefly explained that the task was to build a model of the planetary emission points of the neutrino emitters, which had two requirements.

First, the installation area is relatively secluded and safe.

Second, as far as possible, allow the neutrino stream to cover the largest area without passing through the radioactive layers of the strata.

Although he didn't understand why he wanted to avoid the radioactive layer in the formation, Feng Qingyun still said dutifully:

"In the strata, the radioactivity of the earth's crust is very low, but there is an asthenosphere between the Moho interface at the top of the upper mantle and the crust, which is the closest radioactive layer to our ground."

Feng Qingyun said as he projected the cross-sectional map of the blue star in front of everyone.

The asthenosphere is between 50~250 km deep and can be attributed to part of the upper mantle, which is the place where magma is generated, and it is also a formation with a high concentration of radioactive elements.

The highly concentrated radioactive elements release energy, which heats silicon-magnesium-aluminium oxides to form magma.

This also explains why, many natural marbles are seriously radioactive, and magma is also the reason for the formation of very polymetallic deposits, especially those radioactive minerals, most of which are carried by magma to the earth's crust.

"Then let's start calculating the appropriate neutrino emitter installation point according to the current asthenosphere upper limit." Huang Mingzhe commanded.

"No problem."

The people acted according to their profession.

The upper limit of the asthenosphere from the ground is about 50 kilometers, but this figure is an average, and the oceanic crust is relatively thin among the earth's crust, and the continental crust is relatively thick, these factors need to be taken into account.

The average thickness of the earth's crust is about 17 kilometers, of which the continental crust thickness is larger, with an average of about 39~41 kilometers. The crust is thicker in the mountains and plateaus, up to 70 km; Plains and basins have relatively thin crusts.

The oceanic crust is much thinner than the continental crust, only a few kilometers thick.

The Qinghai-Tibet Plateau is the thickest part of the Blue Star crust, with a thickness of more than 70 kilometers; The crust in the mid-Atlantic submarine valley near the equator is only 1.6 kilometers thick, and the abyssal trench in the eastern Mariana Islands in the Pacific Ocean has the thinnest crust and the thinnest crust on the blue star.

Since the neutrino emitter must be located on a high mountain or plateau, the neutrino flow trajectory cuts into the deepest part of the earth's crust, which is set to a maximum depth of 80 kilometers in the direction of the continental crust and a maximum depth of 30 kilometers in the direction of the oceanic crust.

According to the ground curvature of the blue star and the depth of the earth's crust, it can be calculated that the maximum coverage distance facing the continental crust is about 1200 km, and the maximum coverage distance facing the ocean is about 900 km.

Of course, each region can be adapted to local conditions, after all, the thickness of the crust in each region is different, and there are many situations that need to be considered when arranged on the ground.

For example, the neutrino transmitter installed on the Qinghai-Tibet Plateau can reach a maximum coverage of 2,000 kilometers.

The neutrino transmitter set up on Wuzhi Mountain in Qiongzhou can also cover about 1,100 kilometers.

For example, the highest peak of Wuzhi Mountain in Qiongzhou is 1867 meters, and the neutrino transmitter is arranged at an altitude of 1200 meters, which can naturally increase the direct coverage distance.

This is a ground-facing setting, if it is facing the sky or even outer space, according to Huang Mingzhe's calculation of the neutrino exhaustion rate of high-energy π, the maximum impact distance can reach around 300,000 kilometers.

This range has fully covered the low Earth orbit and synchronous orbit of the blue star, and even part of the lunar orbit will be affected.

Among the researchers present, there are many experts in geology and astronomy, plus the assistance of supercomputing and virtual simulation space.

Soon they had a preliminary completion of the construction of the planetary model.

The arrangement of the edge-center is formed.

On the sideline, there are eight neutrino transmission stations, including the Wuzhishan Transmission Station in Qiongzhou, the Daiyunshan Transmission Station in Fuzhou Province, the Jiaodong Peninsula Transmission Station in Qilu Province, the Laoyeling Transmission Station in Ji Province, the Daxinganling Transmission Station in Mongolia District, the Tianshan Transmission Station in Xinjiang Region, the Tanggula Mountain Transmission Station in the Snow Region, and the Wuliangshan Transmission Station in Yunnan Province.

The central area is set up to defend the sky and outer space, and there are four launch stations, namely: Hefei launch station in Hui Province, Luliang launch station in Jin Province, Hanzhong launch station in Qin Province, and Hengyang launch station in Hunan Province.

These neutrino transmitters cover most of Asia, with the exception of western West Asia and the South Sea Islands in Southeast Asia.

And the sky and outer space, which are covered without dead ends, directly launch high-energy π neutrino streams into outer space on a large scale, and any nuclear weapon that breaks into from outer space will directly become a dud.

Of course, this defense system can only protect most of Asia, and cannot prevent the United States and the Western Continent Alliance from exploding on the spot.

Unless neutrino emitters are placed in outer space, so that the world's nuclear reactions can be suppressed without dead ends.

Unfortunately, according to calculations, a large-range neutrino emitter needs to consume 80~12 billion kWh of electrical energy per year.

Obviously, the solar panels of the satellite are not able to provide such a huge amount of electricity for the time being, and the progress of the nuclear fusion reactor miniaturization project currently being carried out by the Jinwu Project is relatively slow.

In fact, the miniaturization project of nuclear fusion reactors has an impact not only on neutrino emitters, but also on gamma-ray lasers in the Phoenix Project.

After all, a large-range high-energy gamma-ray laser is bound to be an electric tiger, and solar panels simply cannot support this energy consumption.

Of course, with the neutrino emitter arrangement there is bound to be another serious problem.

If these neutrino transmitter stations in China are fully powered, they will be covered, not only will the nuclear weapons become duds, but the operating nuclear power plants will also be paralyzed instantly.

Even fusion reactors can be affected, because neutrons cannot be produced, which will make the chain reaction of the fusion reactor unsustainable.

But Huang Mingzhe has already figured out a solution, which is to arrange neutrino reflection devices around the fusion reactor to reflect these high-energy π neutrinos.
