Release that Witch - Chapter 1359

[Chapter 1321 High Energy Experiment (Part 2)]

Fifteen kilometers away.

The high platform built of steel frames stands in the white snow field, and it does not look like a creation of this era-the regular and dense exposed structure, the beams and steel cables with ice picks hanging, and the barbed wire surrounded by layers all reveal An industrial aesthetic.

Hundreds of people are busy around it, making preparations before detonation.

Since the weight of the entire principle device was close to ten tons, Hummingbird went to the front line again, so the final assembly could not be carried out in Neverwinter, and the parts could only be distributed and dragged to the explosion test site for assembly on site.

Fortunately, its structure itself is very simple, and the need for dismantling and transportation has been considered during the design, so the requirements for workers are not high.

This is also the difference between “Glory of the Sun” and other weapons – even if the venue and equipment have been arranged, it still takes 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 No. 3 core component, pay attention to the direction of the interface, and be careful of bumps!”

“Everyone listen to my password! Three, two, one!”

With the trumpet of the worker captain, a silver-white cylinder was slowly pushed into the device.

It wasn’t until this step was completed that Roland breathed a sigh of relief.

What is contained in the cylinder is the main energy source of this test explosion—two divided uranium-235 cylinders, each of which has a mass of 20 kilograms.

When the two are combined, a total charge mass of forty kilograms will be provided.

This value is lower than the critical limit of 53 kilograms, theoretically no violent fission reaction will occur, but as he said before, the critical value is not a fixed value.

Shape, temperature, pressure and other conditions may cause this value to change, which is why “nuclear weapons” that rely purely on pile materials have little practical value.

For example, fifty-two kilograms of uranium-235 in a spherical state seems to be stable, but it is actually a volcano that is ready to erupt.

Even a little bump or vibration can make it pass the threshold.

Similarly, although it is safe to use multiple small uranium blocks, it will also double the difficulty of detonation-when several uranium blocks are integrated into one, the whole can indeed exceed the critical point, and the high temperature generated by the fission reaction will The rapid expansion of the uranium block reduces its density in a disguised form, and the violent explosion will push the raw materials far away, thereby interrupting the reaction.

All in all, a reasonable configuration must not only allow the uranium element to reach a critical state, but also maintain it in this state for as long as possible in order to exert the power of the fission reaction.

The reason why the gun-type configuration is called the gun-type is that its principle is very similar to the ancient musket. Through the detonation of explosives, one uranium block is violently pushed to another uranium block.

Under enormous pressure, the density of uranium blocks will increase rapidly, even if the mass is slightly lower, it can cross the critical point.

After the shell of the device was connected, Anna personally inserted a can of packaging with a radioactive source warning sign into the reserved tail port.

That was the last key component of the test explosion.

For a moment, Roland felt as if something had stabbed his face, and even his breathing stopped for a while.

“Polonium-Beryllium Neutron Source”.

Just like the name, it can provide a large number of free neutrons for fission, and it is also the most direct way to reduce the critical value.

Inside a metal container like a can, there is a row of hollow spheres—each sphere is about the size of a ping-pong ball. The core is a polonium ball like a marble, which is tightly wrapped in gold foil, and its surroundings are A ring of honeycomb-shaped beryllium sheets.

When the uranium block collides, it will also shatter the small pot at the bottom of the “barrel”. All the hollow balls will be compressed by the violent explosive gas to be thinner than paper. The balls are closely attached to each other, fully accepting the alpha particles released by the latter, and then emitting several times of neutrons.

These neutrons will participate in the fission reaction of uranium 235. If you are lucky, you can consume a few percent more raw materials before the reaction terminates, greatly increasing the power of nuclear weapons.

Since the half-life of polonium 210 is only 138 days, it is essential to provide a replacement interface.

In addition, it is extremely dangerous to keep the neutron source in the weapon for a long time. After all, polonium and beryllium can spontaneously emit neutrons as long as they come into contact. Once the gold foil is damaged, the consequences will be disastrous.

Once the polonium beryllium neutron source was installed in the principle device, it went from a benign and harmless thing to a monster that could engulf everyone in the scene at any time.

Although Roland knew that his feelings were just illusions, and it was impossible for people to capture the changes in the number of neutrons in the environment, his breathing still subconsciously eased a lot.

At this point, the principle device has officially completed all the preparations before detonation.

Anna took the initiative to hold his hand.

“Order.”

Under the peaceful and steady gaze of the other party, Roland nodded slightly.

Regardless of the outcome, the Sun’s Glory Project has finally reached this point.

After taking this step, human beings will go to a new field.

He looked at his personal guard, Xiao En, “Send me an order to notify the command post, the six-hour countdown to ignition!”

“Yes, Your Majesty!”

“6:00”

“woo woo woo woo——”

“Device No. 1 has entered the stage of ignition and ready to go. Repeat, device No. 1 has entered the stage of ignition and ready to go. Please pack up your luggage immediately and leave the field in an orderly manner according to the drill plan! Note that this is not a drill. It will be closed in an hour, everyone must evacuate to a safe place before then!”

Soon, the evacuation notice rang through the audience along with the sound of the siren.

“Hurry up, everyone, gather in the open space in front of the tower, don’t drag anyone down!”

“The second construction team reported the number, one, two, three…”

“The gate of the explosion test station is closed!”

“All the members of the God’s Punishment Witch Squad have arrived and started to lead the team to evacuate.”

The quiet snow field seemed to be boiling, and the people’s shouts and the sirens repeated over and over again complemented each other, and the atmosphere became tense and dignified for a moment.

Everyone knew 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 cover of the console together.

When the switches were pressed one by one, the green lights on the table also lit up one by one.

“The main cable is delivering power!”

“Mystery Moon 1 is working normally, and the load is steadily increasing.”

“Now switch to line one.”

“Understood, line 1 has been connected, and the power supply of the principle device is normal!”

The observers loudly reported the operation of the detonation system until the last green light came on, which meant that the current had passed through multiple booster relays and was conducted to the high platform fifteen kilometers away.

“1:00”

An alarm was also sounded over the command post, which meant that there was only one hour left in the detonation procedure.

All the doors and windows of the bunker were closed, and the oil lamps were extinguished one by one to avoid accidents caused by vibrations.

The Neverwinter high-rise entered a special observation room. According to Roland’s instructions, its outer facade was built into a trapezoid to better resist shock waves, and one end of the interior was deepened to accommodate the huge original carrier. body.

Pasha has been waiting for Witch Takira for a long time.

“0:15”

It was getting dark.

The last round of rapid sirens finally came.

Whether it is high-level, soldiers or workers, they all put on black sunglasses to resist strong light according to the previous training content of the performance.

Although most people don’t understand why they wear glasses that block their vision in this dark and snowy day.

It’s not that I can’t see anything.

“0:05”

“Countdown, five minutes!”

When the announcement sounded again, the scene had become silent.

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

“Three minutes count down!”

Roland felt sweat dripping from his palms.

Anna glanced at him with a smile, and held him gently.

“Count down in one minute!”

On the other side, a hand stretched out, and then fingers interlocked.

“Ten seconds count down!”

“Nine!”

Although it was a pity that he couldn’t press the detonation button himself, Roland knew that this long journey of historical facts had just begun.

“three!”

“two!”

“one!”

“Detonation!”

The snow field in the distance is quiet, as if nothing happened – time seems to be frozen at this moment, it seems that it has passed for a long time, and it seems that there is only a short moment.

Then an extremely dazzling blue light bloomed from the horizon, tearing up the darkness in front of me in an instant!
