Excerpt from a poem written by Ashlock, editor in chief of Berlin daily, to commemorate the accident in 1943（ Excuse me, Xiong Wenqing of East China.)
Slotin is serious.
Two hemispherical beryllium balls are made of plutonium-239. Because beryllium has good neutron reflection properties, it can be guaranteed that no neutrons will penetrate from the inside. In this way, people are safe outside.
Radiation sickness is a terrible disease, but future generations are absolutely hypocritical. After pregnancy, they actually stop their neighbors from using WiFi. It's the biggest thing in the world. It's the most important thing in the world. That point of electromagnetic radiation. If it can cause personal injury, there will be no safe place in the world.
Of course, it is a matter of dose.
When the two balls are close to each other, neutrons will have more opportunities to impact the nucleus. Only experiments can know how close they are.
This is basically the model of an ordinary nuclear bomb. The front and rear hemispheres are detonated with explosives. Pushing the two hemispheres together can complete a terrible chain reaction and become the explosion of a nuclear bomb.
The key is this distance, which is realized by transferring the middle gasket. If the gasket is marked with thickness, you can know the distance, and determine the real and effective critical situation through the response of different distances.
Slotin's expression was not too serious. For him, it was necessary for him to raise his feet if he was light. He had died so many times before, especially during the test flight. Which time was he nervous? If smoking was not forbidden in the laboratory, he really wanted to finish this simple experiment again and again with a cigarette end in his mouth.
Yes, there is no difficulty for him.
Slotin stood in front of the two hemispheres, his left hand easily inserted into the thumb hole, grasped the beryllium upper hemisphere, easily moved down, facing the lower hemisphere on the platform below.
The two hemispheres were originally separated, and the distance between them was very large at the beginning, so Slotin moved very fast.
The scale of the nucleus is quite small. Only when the distance is close to a certain value will there be a terrible chain reaction.
At this time, Slotin's right hand was holding a screwdriver. When the upper hemisphere was about to contact the lower hemisphere, he poked the screwdriver in and put it between the two hemispheres to maintain the gap between the upper and lower hemispheres.
"Move the shims." Slotin greeted.
Although he is the main operator of the experiment, like surgery, only one master knife can't do, and he has to have an assistant.
Slotin has both hands. He holds the upper hemisphere in his left hand and a screwdriver in his right hand. At the same time, an assistant is responsible for converting different shims. The distance between them is changed by this gasket with different thickness.
At this time, there are only two of them on the console. Two colleagues are watching two meters away from them. Further away, in the corner of the room, there are four other personnel responsible for calculation.
The assistant carefully began to draw the filler. The assistant didn't have as good psychological tolerance as sloutin. This thing is very dangerous. In case of an accident, I'm afraid everyone present will die and the whole base will be ruined.
Otherwise, why call it the devil's center?
Just as the assistant had just pulled out the thick shim and had not inserted the thin one, a buzzing sound was heard in his ear.
Damn it, there are mosquitoes in this broken desert. Their vitality is so tenacious, and the mosquitoes in Africa are very powerful. Once they bite a pimple, they may not go down for ten days and a half months.
This mosquito, unexpectedly, flew towards the gap between the two hemispheres?
When the assistant looked at the track of mosquitoes, there was a big hand in front of him.
"Wow!" Slotin's right hand quickly grabbed the mosquito, and his mouth was still laughing: "see if you fly fast or my hand is fast. In a moment, I'll pull your mouth down."
The assistant was stunned.
Where's the screwdriver in your hand? What you want to control is the core of the devil!
"Dong!" A crisp sound appeared in everyone's ears. Sloutin used to hold a screwdriver in his right hand. Now he used his right hand to shoot mosquitoes. The screwdriver poked inside, didn't put it firmly, rolled down twice, and fell to the ground!
In an instant, everyone's eyes looked over, and everyone's eyes were filled with fear.
The shim has just been pulled out and has not been inserted with a new one. Now, the only screwdriver inserted in it has fallen down!
At this moment, sloutin was stunned. What's going on?
Here, mosquitoes are the most annoying. He's right to fight mosquitoes, because the screwdriver is inside. He thinks it's firmly inserted!
But who would have thought that the screwdriver fell down?
It doesn't matter. I still hold it in my left hand!
In order to prevent accidents, Slotin is prepared with both hands, a screwdriver in his right hand and a beryllium ball in his left hand.
Not afraid, not afraid.
Slotin's psychological quality is quite strong. This sudden situation is nothing at all. Now, his left hand is firmly grasping the upper hemisphere!
Shit, no!
Just then, suddenly, his left hand slipped.
"Dong!" The voice was not loud, lighter than the voice just now, but at this moment, death had been announced.
If he knew he was easy to sweat, Slotin would put some anti-skid powder on his hands before doing the experiment!
The current situation also exceeded Slotin's expectations. He stayed for a while.
The plutonium block on the top is in close contact with the plutonium block on the bottom, just as two cut eggs are aligned, and the egg yolk is completely aligned.
At the moment of contact, the terrible chain reaction started.
A neutron impact produces four neutrons, bombards four atomic nuclei, generates sixteen neutrons, and continues to bombard... Almost every impact reaction takes place in a shorter time than microseconds.
Neutrons can't come out. The outer shell of beryllium wraps all neutrons, reflects them back and continues to participate in the reaction.
As a result, the impact chain continues to extend downward, with more and more behind. This is the terrible thing of the exponential level. The neutron density grows wildly in microseconds. Every time a new neutron is generated, it will continue to bombard other plutonium atoms to produce energy and more neutrons
There is no barrier between the two plutonium hemispheres. Neutrons are growing wildly, and at the same time, energy is growing wildly at a terrible speed.
The fission of a single atomic nucleus releases only a few hundred MeV of energy, but the advantage of quantity makes it quickly become a macro terrible energy.
In a short time, when the gap between the two balls and the plane parallel to the gap expand to the whole room, you can see the blue fluorescence generated by air ionization. At the same time, a huge heat wave has hit everyone's cheeks.
It's over!
Please report us if you find any errors so we can fix it asap!
Scientists with great souls, may God welcome you!
