Release that Witch Chapter 1192: People of Windseeker

The neutron source can be understood as a fission catalyst. With the additional neutrons it provides, even uranium 235 below the critical mass can be efficiently split. .

In theory, thorium and radium separated from uranium ore can form a neutron source with beryllium. There is no technical problem in this. It is purely the use of beryllium to release a large number of neutrons when bombarded by a particles. Features really work as long as they come together. All three are naturally-occurring substances, and their feasibility is undoubtedly much higher than those artificial elements that are extremely difficult to serve or need to be reproduced by handyman art.

As for Roland, radon was selected instead of radium, purely for safety reasons. Although the half-life of radon 210 is short, it is basically a decay, and the gamma photon yield is extremely low. In other words, as long as it is not eaten, it is almost as safe as uranium. Radium is different. Whether it is the radon generated by subsequent decay or the gamma photons emitted by itself, it is a safety hazard that cannot be ignored. In order to avoid accidents during the experiment, the europium-beryllium neutron source became the most suitable choice.

In addition, beryllium also has the property of reflecting neutrons. If it is used as a shell, it can further increase the efficiency of neutron utilization. If both are used together, plus a sufficient amount of uranium 235, even the simplest and most reliable gun-type structure can achieve good results.

Beryllium is widely present in green gem. Such a distinctive mineral saves the effort of Azima to travel through mountains and rivers. As long as the news is released through the merchant channel, then it will be alright is widely acquired in Four Great Kingdoms.

Roland is very clear about the technical level of Neverwinter City. The principle of bright radiation is simple, but every 10% increase in utilization rate is a threshold, from 1% to 90% or more. There is no need for massive theoretical calculations and experiments. Correction. If high-efficiency energy release is not achieved, impossible will make weapon miniaturize, and it will also waste weapon-grade uranium that has been accumulated. Without Lucia, the loss of refining alone is an insurmountable peak.

But again, rubbing a nuclear bomb by hand is not just a joke in the case of situation that can afford it, or does not care about it. Technological thresholds vary widely, but the principles remain the same. Thanks to the inherent advantages of mass conversion to chemical gunpowder, even if only 1% of uranium participates in fission, its power is enough to reverse the war.

He will do his best in this battle of life and death that determines the fate of the ethnic group.

Not to mention stealing the magical fire and reducing the distance between human beings and the sun in such a barren age?

He is willing to try whenever possible.

"Very good, just keep it like this," Roland patted Lucia's head, "When all lead cabinets are full, you can start the formal test."

"Yes, Your Majesty!" Lucia is full of energy.

*******************

At the same time, Neverwinter City, Aerial Knight school.

This is located in the west of the new institute. It is also a quiet area in a huge area. Today is the time for students to take a vacation. Most people leave the campus early to enjoy the time of reuniting with their families. Gourd is an exception.

"Upwind, put down!"

"Crosswind, roll!"

He was sitting on the simulated bridge, while setting the wind direction for himself, while responding according to the regulations in the "Flight Manual", the wooden rod squeaked, like an old one. Disrepaired waterwheel. The temperature in the training room was quite sultry. After a long period of practice, his back was soaked with sweat, and sweat beads dripped from the chin from time to time, scattered on the rudimentary "dashboard".

Gourd did not stop until the grip slipped and leaned on the chair released a long breath.

After nearly half a year's study, he is no longer the first layman. The "Flight Manual" prepared by Her Royal Highness does not fall into such a mess, and the basic operations can be said to be all printed in her mind. From the beginning, when I got on the bridge, I was busy, and now I can operate with my eyes closed. If I give an order by myself, I don't even need to say a word. As long as I have a thought, my body will react immediately.

But can you fly yourself?

No matter how he imagines, he can't outline the upwind in his mind. Capturing the direction and magnitude of the wind, feeling the posture and tremor of the body, and then exerting coordinated operating forces This is the original word in the manual, but he has no idea what it feels like. Whether he pulled it halfway or pulled it to the end, the driver's console would not give him any feedback. As for the "dashboard" drawn with ink lines, it was more like laughing at his efforts.

The more proficient you are in your movements, the more frustrated Gourd will be.

Just as he was a little upset, the door of the training room suddenly creaked open.

"You are really here"

"How about, I guess right?"

Gourd turned back and looked at the two people walking into the room unexpectedly. They were the Finkin and Heinz of the same team. "How do you ..."

"Don't take advantage of vacations to find fun?" Finkin whistleed, "Because the fun is in school."

"It's you, you just don't have a family, don't you obviously have a lovely sister?" Heinz stepped forward and grabbed his neck, "She asked me not to get tired, oh ... … It ’s so good. "

Gourd's expression suddenly tightened. "Wait, you two went to where I live?"

"Nonsense, otherwise where shall we find you?" Finkin raised an eyebrow at him. "She's called Rachel, isn't it, how about introducing us?"

"Don't even think about it," Gourd glanced at the other person.

"Do you think our conditions are not enough," Finkin refused, "at least I have a formal residence in the Scarlet Water River community!"

Gourd was silent for a while, and finally shook her head helplessly, "It has nothing to do with you, but my sister ... Rachel her own problem. You won't want to be with her."

"Why? I think she's pretty good," Heinz puzzled.

"Speak to hear?" Finkin was also curious.

"Don't ask this," Gourd said badly. "Say something else. The fun you said before, is it What does it mean?"

Finkin didn't continue entanglement, he lowered his voice and said mysteriously, "Do you want to try a real airplane?"

Gourd could not help but hold back, "What did you say?"

"I saw it when I climbed the wall a few days ago," Finkin smiled slightly proudly. "Several new planes were transported into the warehouse of the flight site. Although they are covered with cloth, they are all large and small. It's similar to the The Unicorn piloted by Her Royal Highness. In other words, it's a plane prepared for us! "

"A few days ago? Why didn't you say it?"

"I'm not afraid that you're over-excited and leaked the news." He shrugged. "Today is a holiday. There are only a few people in school. It's the chance to slip in and see what it looks like!" /

"You are crazy!" Gourd did not dare to set up a channel, "Without permission, we cannot enter the flight field at will!"

"Will those soldiers not let you in, okay." Finkin gave him a glance at him, "Of course he went the other way and did not pass through the airfield."

"But ..."

"We just took a look," Heinz also said, "You should feel it, Your Highness Tilly has a lot of smiles and a lot of strict training recently. Maybe you still have to wait. It will take a month or two to really touch it. Compared to this humble wooden table, don't you want to see in advance what the airplane we are going to look like?

"If you don't want to go, let's take a step Oh. first" Finkin frowned.

Gourd hesitated for a long time, and the boring and squeaking sound of the wood when he fiddled, and the lack of progress no matter how he practiced, finally he bit his lip and nodded, "I go , Lead the way. "
