Chapter 1663: Hand 1 slip

Scientists with great souls, may God welcome you!
When you are with us, even strangers know
Your wisdom and reputation
Not only in the melting pot of death
We finally see your noble heart
Excerpted from a poem written by Ashlock, editor-in-chief of Berliner Zeitung in 1943, to commemorate the accident. (Excuse me for being a young man of East China.)
Slotin is serious.
Two hemispherical beryllium with plutonium-239 inside. Because beryllium has good neutron reflection properties, it can be guaranteed that no neutrons will penetrate from the inside, so that people are safe outside.
Radiation sickness is a terrible disease, but people in later generations are absolutely over-hypothetical. After pregnancy, preventing neighbors from using Wi-Fi is simply the biggest in the world. She has a baby that is the most important thing in the world. If radiation can cause personal injury, there is no safe place in the world.
Of course, this is a matter of dosage.
When the two are close to each other, the neutrons will have more chances to impact on the nucleus and how close they are. This is only known by experiments.
This is basically the model of an ordinary nuclear bomb, with two hemispheres in the front and the back, and the explosives at the back detonate. Pushing the two hemispheres together can complete a terrible chain reaction and become a nuclear bomb explosion.
The key is this distance. This is achieved by transferring the spacer in the middle. The thickness is marked on the spacer to know the distance. Through the reaction of different distances, the true and effective critical situation can be determined.
Slotin's expression didn't have much seriousness. For him, it is necessary for him to hold his feet lightly. He died so many times before, especially during the test flight, when was he nervous? If it weren't for the ban on smoking in the laboratory, he would really want to finish this simple experiment with his cigarette over and over again.
Yes, there is nothing difficult for him.
Slotin was standing in front of the two hemispheres, his left hand easily inserted into the thumb hole, grasping the upper hemisphere made of beryllium, and moving down easily, facing the lower hemisphere placed on the platform below.
The two hemispheres were originally separated, and the distance between them was very large at the beginning, so Slotin moved quickly.
The scale of the nucleus is quite small, and only when the distance is close to a certain value, a terrible chain reaction will occur.
At this time, Slotin's right hand was holding a screwdriver. When the upper hemisphere was about to touch the lower hemisphere, he stabbed the screwdriver in and pushed it in between the two hemispheres, maintaining the gap between the upper and lower hemispheres.
"Move the shims." Slotin greeted.
Although experimenting with his main manipulator, it is the same as performing an operation. Only one surgeon is not enough, and an assistant is required.
Slotin took up both hands, holding the upper hemisphere in his left hand, and a screwdriver in his right. At the same time, beside him, an assistant was responsible for switching between different shims. Through this gasket of different thickness, to change the distance between them.
At this time, on the console side, there were only two of them. Two meters away from them, two colleagues were watching, and further away, in the corner of the room, four other personnel were responsible for the calculation.
The assistant carefully started to draw the shims, but the assistant did not have the mental tolerance of Slotin. This thing is quite dangerous. If an accident happens, everyone present will die and the entire base will be ruined.
Otherwise, why call it Devil Ball Heart?
Just as the assistant had just pulled out the thick shim, and had not inserted the thin one, at this moment, I heard a buzzing sound in my ear.
Damn, there are mosquitoes in this desert. The vitality is so tenacious. And this African mosquito is quite powerful. Once you bite a pimple, you may not get it for ten and a half months.
This mosquito flew into the gap between the two hemispheres desperately?
When the assistant was watching the trajectory of the mosquito, there was a big hand in front of him.
"Wow!" Slotin's right hand quickly grabbed the mosquito, his mouth was still laughing: "Look at whether you are flying fast or my hand is fast. In a moment, I will take your Pull your mouth down."
The assistant was stunned.
Where is the screwdriver in your hand? What you want to control is the core of the devil!
"Boom!" A clear voice appeared in everyone's ears. Slotin was originally holding a screwdriver in his right hand, but now he used his right hand to slap the mosquitoes. The screwdriver was stuck in it. Down, it 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 replaced with a new one. Now, the only screwdriver inserted in it has fallen down!
At this moment, Slotin was also shocked, what's the matter?
Here, the mosquitoes are the most annoying. He is right to hit the mosquitoes, because the screwdriver is inside, he feels it is firmly inserted!
But who would have thought that the screwdriver would fall down?
It doesn't matter, I'm still holding it with my left hand!
In order to prevent accidents, Slotin prepared with both hands, a screwdriver in his right hand and the upper part of the 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!
I rely on ~EbookFREE.me~ not good!
At this moment, suddenly, his left hand slipped.
"Boom!" The voice was not loud, it was lighter than just now, but at this moment, the arrival of the of death had already been announced.
If you know you are prone to sweating, Slotin will definitely put some anti-slip powder on your hands before doing the experiment!
The current situation also exceeded Slotin's expectations, and he stayed for a while.
The upper plutonium block is in close contact with the lower plutonium block, just as if two cut eggs are aligned, and the yolks are aligned completely.
At the moment of contact, the terrible chain reaction started.
One neutron impact produces four neutrons, bombards four nuclei, generates sixteen neutrons, and continues bombarding...Every impact reaction occurs almost in a shorter time than microseconds.
The neutrons can't get out either. The outer shell of beryllium envelops all the neutrons, reflects them back, and continues to participate in the reaction.
As a result, this impact chain continues to extend downward, and more and more behind, this is the exponential horror. The neutron density grows wildly in microseconds, and each new neutron will continue to bombard other plutonium. Atoms, generating 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 terrifying speed.
The fission of a single atomic nucleus releases energy of only a few hundred megaelectron volts, but the advantages of quantity make it quickly become a terrifying energy on the macro.
In a short period of time, the gap between the two balls, the plane parallel to the gap, expands to the entire room, and the blue fluorescence produced by air ionization can be seen. At the same time, a huge heat wave has hit everyone Cheeks.
