A neutron source can be understood as a catalyst for fission, and with the additional neutrons it provides, even uranium 235, which is below the critical mass, can be efficiently split.
Theoretically, polonium and radium separated from uranium ore can form a neutron source with beryllium. There is no technical problem in this. It purely uses the characteristic that beryllium will release a large number of neutrons when bombarded by a particle. It can really take effect as long as it gets together.
All three are naturally occurring substances, and their feasibility is undoubtedly much higher than those artificial elements that are extremely difficult to handle or require complex processes.
As for Roland's final choice of polonium instead of radium, it was purely for safety reasons. Although the half-life of polonium 210 is short, it is basically a decay and the yield of gamma photons is extremely low.
That is to say, as long as it doesn't eat it, it's almost as safe as uranium.
Radium is different. Whether it is the subsequent decay of radon gas or the gamma photons emitted by itself, they are safety hazards that cannot be ignored.
In order to avoid accidents during the experiment, the polonium-beryllium neutron source has become the most suitable choice.
In addition, beryllium element also has the property of reflecting neutrons. If it is used as a shell, it can increase the utilization efficiency of neutrons in a closer manner.
If both are used at the same time and a sufficient amount of uranium 235 is added, even the simplest and most reliable gun-type structure can achieve good results.
Beryllium is widely present in emeralds, and such distinctive minerals save Aqima from searching for mountains and rivers. As long as the news is released through merchant channels, it is enough to widely acquire it in the four kingdoms.
Roland knew very well what level of Wu Winter City's technical level is. The principle of brilliant radiation is simple, but every 10% increase in utilization is a threshold, from 1% to more than 90%, which requires massive theoretical calculations and experimental corrections. If the energy is not released efficiently, it is impossible to miniaturize the weapon, and the weapon-level uranium that has finally accumulated has been wasted.
Without Lucia, the loss of refining alone would be an insurmountable peak.
But in the same way, rubbing a nuclear bomb with a hand is not just a joke when it is affordable or not caring about losses.
The technical thresholds vary greatly, but the principles are consistent. Thanks to the inherent advantages of mass-energy conversion on chemical gunpowder, even if only 1% of uranium participates in fission, its power is enough to reverse the situation.
In the face of this life-and-death battle that determines the fate of the race, he will do his best.
What's more, stealing divine fire in such a wilderness era and bringing humans closer to the sun is also a kind of romance?
He is willing to give it a try as long as there is a slight possibility.
Very good, just keep it like this, Roland patted Lucia on the head, and when all the lead cabinets were full, the formal experiment could be started.
Yes, Your Majesty!Lucia was very energetic.
*******************
At the same time, there is no Winter City, the Sky Knight Academy.
This area is located west of the new institute, and it is quiet in a huge area. Today is the day for students to take a vacation. Most people leave the campus early to enjoy the time to reunite with their families, while Goode is an exception.
Upwind, press the rod!
Crosswind, roll!
He sat on the simulated bridge, setting the wind direction for himself, and responding according to the regulations in the Flight Manual. The wooden pole made a squeaking sound, like an old and disrepaired water truck.
The temperature in the training room was quite stuffy. After practicing for a long time, his back was soaked with sweat, and sweat beads dripped from time to time on his chin, sprinkling on the simple instrument panel.
It wasn't until the handle slipped that Goode stopped and leaned on the chair and breathed a sigh of relief.
After nearly half a year of study, he is no longer the first layman who knows nothing. The "Flight Manual" written by His Royal Highness the Princess is memorizing it, and the basic operations can be said to be all imprinted in his mind.
From being busy when I got on the bridge at the beginning, to now, I can operate according to the command with my eyes closed. If I order myself, I don’t even need to say it. With just one thought, my body will react as soon as possible.
But can this make yourself fly?
No matter how you imagine it, he could not outline the scene of surging up against the wind in his mind.
Capturing the direction and size of the wind, feeling the posture and tremor of the body, and then exerting the coordinated operating force. This is the original words in the manual, but he had no idea what it felt like.
Whether it is gently pulling half or pulling to the end, the bridge will not give him any feedback. As for the dashboard drawn with ink lines, it seems to be mocking his efforts.
The more skilled he practiced the movements, the more frustrated he felt.
Just when he was a little upset, the door of the training room suddenly creaked and was pushed open.
You're indeed here
How about it, I guess right?
Goode turned around and looked at the two people walking into the room with a little surprise. They were Fenkin and Heinz from the same team. Why are you...
Don't use vacation to find fun?Fenkin whistled, because the music was in the academy.
But you, it would be fine if you don’t have family, don’t you have a cute sister?Heinz walked up and hooked his neck, and she told me not to be tired, tsk... It's so good.
Good's expression suddenly tightened, wait, did you two go to where I live?
Nonsense, otherwise where will we find you?Fenjin raised an eyebrow at him, her name is Rachel, right? How about introducing it to us?
Don't even think about it, Goode glared at him.
Do you think we are not in good condition? Fenjin is not convinced. At least I have a formal residence in Chishuihe Community!
Goode was silent for a moment, and finally shook his head helplessly, "It has nothing to do with you, but my sister... Rachel's own problem."You won't want to be with her.
Why?I think she is pretty good, Heinz wondered.
Let’s hear it?Fenkin was also curious.
Don't ask this, Goode said irritably, say something else, what does the fun you mentioned before mean?
Fenjin didn't continue to pester. He lowered his voice and said mysteriously, Do you want to try a real plane?
Goode couldn't help but be stunned, what were you saying?
I saw it while climbing the wall a few days ago, Fenkin showed a slight smug smile. Several new aircraft were transported into the warehousing in the flight grounds. Although it was covered with cloth outside, it was similar to the unicorn that Her Royal Highness was flying.That is, that is the plane for us!
Several days ago?Why didn't you say that?
I'm not afraid that you will be overly excited and leak the news.He shrugged, and today is a holiday, and there are only a few people in the academy, and it is the opportunity to sneak in and see his true face!
You're crazy!Goode dared not believe it. Without permission, we cannot enter the flight field at will!
Those soldiers won't let you in, okay?Fen Jin gave him a blank look, of course he was going on another road, and not passing through the flight ground.
But……
We just went to take a look, Heinz also said to you, you should feel that His Highness Tilly has smiled a lot less recently and has been training much more strictly.If this continues, maybe you will have to wait a month or two before you can really touch it.Compared to this simple wooden platform, don’t you want to see in advance what the plane we are going to drive looks like?
If you don't go, we'll take a step first.Fenjin winked.
Goode hesitated for a long time, and the boring and dull creaking sound of the wooden pole when fiddling, and the confusion that he could not make progress no matter how he practiced. Finally, he bit his lip and nodded, "I'll go, lead the way."
