Release that Witch Chapter 1321: High-energy experiment (below)

Fifteen kilometers away.

The steel-framed high platform stands in the white snowfield. It looks a bit like the creation --'s regular dense structure, the beams and steel cables with ice cones, and the barbed wire surrounded by layers. Reveal the beauty of industry.

Hundreds of people were busy around him, preparing for the detonation.

Because the weight of the entire principle device is close to ten tons, Hummingbird has gone to the front line, so it cannot be assembled in Neverwinter City. It can only be distributed to the test explosion site and assembled on site.

Fortunately, the structure itself is very simple. In addition, the need for split shipping was considered in the design, and the requirements for workers are not high.

This is also the difference between "Splendor of the Sun" and other weapon -- Even if the venue and equipment have been arranged, it will still take a day or two to complete the final preparations.

At this moment Roland and Anna are standing on the top of the tower, directing the assembly of the device.

"Next is the core part three, pay attention to the direction of the interface, be careful!"

"Everyone listen to my password! Three, two, one!"

With the worker's Captain horn, a silver-white cylinder was slowly pushed into the device.

Until this step is completed, Roland is relieved.

The two uranium 235 cylinders packed in the cylinder are the main energy sources of this test explosion, --. The mass of each block is 20 kg. When the two are combined, it will provide a total charge of forty kilograms. This value is lower than the critical limit of 53 kilograms. In theory, no fission reaction will occur severely, but as he said before, the critical value is not a fixed value.

The shape, temperature, pressure and other conditions may cause this value to change, which is why the "nuclear weapon" which is purely based on stacking materials has little practical value. For example, in the state of a sphere, 52 kilograms of uranium 235 seems to be stable, but it is actually a volcano that is ready to erupt. Even a little shock or vibration can make it cross the border.

Similarly, although it is safe to use multiple small uranium blocks, it will double the difficulty of detonation. -- When several uranium blocks are combined into one body, the whole can indeed exceed the critical point. The high temperature will cause the uranium block to expand rapidly, reducing its density in disguise, and the severe explosion will push the raw materials away from the distance, thus interrupting the reaction.

In short, a reasonable configuration must not only make uranium critical, but also maintain it in this state for as long as possible in order to exert the power of the fission reaction.

Gun-type configuration is called a gun type because its principle is very similar to that of the ancient firearms. Through the detonation of explosives, one uranium block is suddenly pushed to another uranium block. Under great pressure, the density of uranium blocks will increase rapidly, even if the mass is slightly lower, it can cross the critical point.

After the device's case was connected, Anna personally inserted a can of the package coated with the warning sign of the radioactive source into the reserved tail connector.

That was also the last key component of this test explosion.

For a moment, Roland seemed to feel something stuck on his face, and even stopped breathing for half a beat.

"polonium-beryllium Neutron Source".

As the name suggests, it can provide a large number of free neutrons for fission and is the most direct way to reduce the critical value. Inside a can-like metal container, a row of hollow **** -- is placed. Each ball is similar in size to a ping-pong ball. The core is a marble-like shuttlecock and it is wrapped in gold foil. Loop honeycomb beryllium flakes.

When the uranium blocks collide, they will also smash this small jar located at the bottom of the "gun barrel". All hollow **** will be pressed thinner than paper by the violent explosive gas. After the gold foil is broken, the beryllium sheet It will be intimately attached to the shuttlecock, accept the alpha particles emitted by the latter, and then emit several times the neutrons.

These neutrons will participate in the fission reaction of uranium 235. If you are lucky, you can consume several percent more raw materials before the reaction is terminated, which greatly enhances the power of nuclear weapon.

Since the half-life of 钋 210 is only 138 days, it is essential to provide a replacement interface. In addition, it is extremely dangerous to leave the neutron source in weapon for a long time. After all, polonium-beryllium can emit neutrons as long as it is in contact. Once the gold foil is damaged, the consequences are unthinkable.

After the polonium-beryllium neutron source is installed in the principle device, it has changed from a mild and harmless thing to a monster that is likely to be everyone at the absorb scene at any time.

Although Roland knows that its feelings are only an illusion, and human impossible captures changes in the number of neutrons in the environment, his breathing is still subconsciously lighter.

At this step, the principle device is officially completed all the preparations before detonation.

Anna took his hand.

"Order it."

In the other's calm eyes, Roland nodded slightly.

Regardless of the outcome, the Splendor of the Sun plan has finally come to this point.

After this step, humanity will go to a new field.

He looked towards personal guard Sean, "Pass me an order and inform the command post, the fire will count down in six hours!"

"As you bid, Your Majesty!"

"6:00"

“woo -- --—woo -- --—woo -- --—woo -- -- --”

"The No. 1 device has entered the ignition-ready phase. Repeat. The No. 1 device has entered the ignition-ready phase. Please pack the equipment immediately and leave the orderly according to the exercise plan! Note that this is not an exercise. The explosion will be closed in an hour, and everyone must evacuate to a safe place before that! "

Soon, the evacuation announcement went through the hall with the sound of the alarm.

"Fast and fast, everyone gathers in the open space in front of the tower, don't pull the next one!"

"The construction team reports the number, one, two, three ..."

"The test door is blocked!"

"All members of the God Punishment Witches team have arrived and started to lead the team to evacuate."

The quiet snowy field seems to be boiling. People's shouts and repeated alarm sounds contrast with each other, and the atmosphere becomes tense and dignified. Everyone knew in their hearts that they were about to witness an unprecedented experiment.

「3:00」

In the command post, Roland and Anna took out two keys and opened the console cover.

When the switches are pressed one by one, the green lights on the table turn on in turn.

"The main cable is delivering power!"

"Mystery Moon One is working normally, and the load is steadily increasing."

"Switch to line one now."

"Understand that once the line is connected, the principle device is powered normally!"

The observer loudly reported the operation of the initiation system, situation, until the last green light came on, meaning that the current had been passed through multiple boosts and conducted to a platform 15 kilometers away.

「1:00」

The alarm also sounded over the command post, which meant that the last hour of the detonation procedure was left.

bunker The doors and windows are fully closed and the oil lamps are extinguished one by one to avoid accidents caused by vibration.

The Neverwinter high-rise enters a special observation room. According to the instructions of Roland, its facade is built into a trapezoid to better resist shock waves, while the inner end is deepened to accommodate the huge Original Carrier. Body.

Taquila witch such as Pasha has been waiting for a long time.

「0:15」

It's getting dark.

The final round of sirens has finally arrived.

Whether it is high-level, soldiers, or workers, they have put on black sunglasses to resist glare in accordance with the previous training content.

Although most people do n’t understand why you should wear this pair of sight-blocking glasses in this dim snowy day.

It's not seeing anything.

「0:05」

"Countdown, five minutes!"

When the announcement sounded again, the scene became silent.

All communication and discussions have been stopped. Everyone is staring intently at the dark front, holding their breath involuntarily.

"Countdown in three minutes!"

Roland felt the sweat on his palm.

Anna glanced at him with a smile, holding him gently.

"Countdown to one minute!"

The other hand also stretched over, and then five fingers crossed.

"Countdown to ten seconds!"

"Nine!"

Although it's a pity that you can't press the detonate button yourself, Roland knows that this long historical fact has just begun.

"Three!"

"Two!"

"One!"

"Initiation!"

The snowy field in the distance is quiet. It seems that nothing happened. -- seems to freeze at this moment. It seems to be a long time later, and it seems like only a short moment.

Then a dazzling blue light bloomed from the horizon, and instantly tore the darkness in front of you!
