Release that Witch

Fifteen kilometers away.

The high platform of the steel frame stands in the white snowfield, and it looks a bit like the creation of this era – the regular dense structure, the beams and steel cables with ice cones, and the wire mesh surrounded by layers, all revealed. The beauty of the industry.

Hundreds of people gathered around them to do the preparations before the detonation.

Since the entire principle of the device weighs nearly ten tons, Hummingbird went to the front line, so it was not possible to carry out the final assembly in Neverwinter City. Only the parts were towed to the test site and assembled on site.

Fortunately, its structure itself is very simple, plus the design has considered the need for split transport, the requirements for workers are not high.

This is also the difference between “the sun’s glow” and other weapons – even if the site and equipment have been laid out, it still takes a day or two to complete the final preparation.

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

“Next is the core component of the third, pay attention to the interface direction, be careful!”

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

Along with the worker’s Captain, a silver-white cylinder was slowly pushed into the device.

It was not until this step was completed that Roland was relieved.

The main source of energy for this test explosion is the two uranium 235 cylinders, each of which has a mass of 20 kilograms. When the two are combined, a total charge of forty kilograms will be provided. This value is below the critical limit of 53 kilograms. Theoretically, no fission reaction will occur, but as he said before, the criticality is not a fixed value.

Conditions such as shape, temperature, pressure, etc. are likely to cause this value to change, which is why the “nuclear weapon” of the pile material alone has little practical value. For example, 52 kilograms of uranium 235 in the state of the sphere seems to be stable, but it is actually a volcano ready to erupt. Even if it is a little shock or vibration, it is possible to make it exceed the threshold.

Similarly, the use of multiple small uranium blocks, although safe, will also make the difficulty of detonation multiplied – when several uranium blocks are integrated, the whole can indeed exceed the critical point, and the high temperature generated by the fission reaction will The uranium mass expands rapidly, the disguise reduces its density, and the violent explosion pushes the material away from the distance, interrupting the reaction.

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

The gun configuration is called the gun type, because its principle is very similar to that of the old musket. Through the detonation of explosives, a uranium block is pushed to another uranium block. Under great pressure, the density of uranium blocks will increase rapidly, even if the quality is slightly lower, it can cross the critical point.

When the device’s outer casing was attached, Anna personally inserted a can of the package with the radioactive source warning sign into the reserved tail port.

That was also the last key component of the test.

For a moment, Roland seemed to feel that his face was tied, and he even paused for half a beat.

“钋-铍 neutron source”.

Just like the name, it provides 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, there is a row of hollow balls – each ball is about the size of a table tennis ball, the core is a marble-like ball, and it is wrapped in gold foil, and it is surrounded by A circle of honeycombed sepals.

When the uranium blocks collide, they will also smash the small jar at the bottom of the “barrel”. All the hollow spheres will be pressed by the violent explosive gas to be thinner than the paper, and after the gold foil is broken, the cymbals will be smashed. The balls are intimately attached together and accept the alpha particles released by the latter, which in turn ignites several times the neutrons.

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

Since the half-life of 钋210 is only 138 days, providing a replacement interface is an essential design. In addition, it is extremely dangerous to leave the neutron source in the weapon for a long time. After all, the neutron can be self-issued as long as it is contacted. Once the gold foil is damaged, the consequences are unimaginable.

After loading the neutron source into the principle device, it changes from a mild and harmless thing to a monster that can potentially absorb all the people at the scene.

Although Roland knows that his feelings are just illusions, people impossible to capture changes in the number of neutrons in the environment, but his breathing is still subconsciously lighter.

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

Anna took his hand.

“Order it.”

In the calm and calm eyes of the other side, Roland nodded slightly.

Regardless of the outcome, the Sunlight Project has finally reached this point.

After this step, humans will travel to a new field.

He looked at personal guard Sean, “pass me orders, inform the command post, countdown to six hours!”

“Follow, Your Majesty!”

“6:00”

“woo woo woo woo——”

“The No. 1 device has entered the ignition waiting stage, repeating, the No. 1 device has entered the ignition waiting stage, please immediately pick up the equipment and remove the line according to the drill plan! Note that this is not an exercise, the test will be Closed after an hour, everyone must be evacuated to safety before this!”

Soon, the evacuation announcement rang with the alarm sound.

“Quick and fast, everyone gathers in the open space in front of the tower, don’t pull the next person!”

“The second team of construction reports, one, two, three…”

“Test the door of the explosion block!”

“The God Punishment Witches team is all in place and begins to lead the team to evacuate.”

The quiet snowfield seemed to boiling, and the shouts of people and the repeated sounds of the alarms repeated over and over again, the atmosphere became tense and dignified. Everyone knows that they are about to witness an unprecedented experiment.

“3:00”

In the command post, Roland and Anna pulled out two keys and opened the cover of the console together.

When one switch is pressed, the green light on the table also lights up in sequence.

“The main cable is sending power!”

“Mystery Moon is working fine and the load is rising steadily.”

“Now switch to line one.”

“Understand that the line is connected, the principle device is powered normally!”

The observer loudly reported the operation of the detonation system until the last green light was on, meaning that the current had passed through multiple boosts and was transmitted to a high platform 15 kilometers away.

“1:00”

The command post also sounded an alarm, which meant that the detonation program was only the last hour left.

The bunker doors and windows are closed completely, and the oil lamps are also annihilated one by one to avoid accidents caused by vibration.

The Neverwinter high floor entered a special observation room. According to Roland’s instructions, its façade was built into a trapezoidal shape to better resist the shock wave, while the inner end was deepened to accommodate the enormous body of the Original Carrier. .

Parchi and other Tachila Witch have been waiting for a long time.

“0:15”

The sky is getting darker.

The last round of rushing alarms finally arrived.

Whether it is a high-rise, a soldier or a worker, they wear black sunglasses against the glare according to the previous practice.

Although most people don’t understand why, in this dark snowy day, wear this pair of glasses that obstruct the line of sight.

This is not something that can’t be seen.

“0:05”

“Countdown, five minutes!”

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

All the exchanges and discussions have been suspended, and everyone stared intently at the dark front, involuntarily holding their breath.

“Three minutes countdown!”

Roland felt a sweat in his palm.

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

“One minute countdown!”

On the other side, there is also a hand that stretches over, and then the five fingers overlap.

“10 seconds countdown!”

“nine!”

Although it is a pity that I can’t press the detonation button personally, Roland knows that this long historical road has just begun.

“three!”

“two!”

“One!”

“Detonation!”

The snowfield in the distance is quiet, and it seems that nothing happened. Time seems to solidify at this moment, like it has been a long time, and it seems to be only a short moment.

Then a very dazzling blue light bloomed from the horizon, and the darkness in front of it was shredded in an instant!
