If the efficiency of the laser head is not solved, it will be difficult to reduce the overall energy consumption of the photonic engine.

Once a large-scale space voyage is carried out, this problem will seriously affect the endurance of the spacecraft, and if this problem is not solved, the same energy will be consumed, and the range of the spacecraft of the Human Innovation Alliance will be less than half of that of the Anrox people.

This will not only increase the cost of navigation, but also increase the rate of consumption of fuel resources, which must be addressed in order to plan for the future.

Of course, given the current tensions, the first sub-light spacecraft of the Human Innovation Alliance has been designed, a light spacecraft with a single-photon engine and an overall mass of about 3,000 tons, which is a typical experimental spacecraft.

"Li Xiang, we are divided into two ways, you are responsible for the research and development of alternative materials, and I am responsible for the artificial synthesis method of radium." Huang Haojie commanded directly.

Li Xiang nodded, he was not very good at synthesizing elements, which involved nuclear physics.

Institute of Materials, Branch 11.

Located deep underground in the Qaidam Basin in Qinghai Province, the institute was formerly the nuclear physics research base of the Dongtang Academy of Sciences, but has now been merged into the 11th branch of the Materials Research Institute.

It specializes in the research and development of nuclear materials.

Huang Haojie's stand-in robot took the train through the underground tunnel and entered this secret research institute base deep underground.

"The Führer is welcome to come and inspect the work." Chen Xiangqian, director of the institute, and Pavlo, chief engineer?? Korostrov hurriedly said.

Bang Bang Bang ...... Others hurriedly applauded.

"Everyone has worked hard, you're welcome, I'm here this time to develop the artificial synthesis of radium." Huang Haojie waved to everyone.

"Yuan Xiansheng, I'm very happy to meet you, I'm Pavlo?? Korostrov, Chief Engineer of the 11th Branch of Materials. "Pavlo?? Kolostrov excitedly shook Huang Haojie's hand and said.

"It turned out to be Mr. Pavlo Kolostrov from the Moscow Institute of Nuclear Physics, I am very happy to meet you, we will talk as we walk." Huang Haojie said.

"It's a great honor." Pavlo?? Korostrov hurriedly said.

Chen Xiangqian, who was on the side, also hurriedly led the way to the inside of the institute, and he and Pavlo Korostrov introduced the internal situation of the institute to Huang Haojie while walking.

"Has the equipment I sent someone to escort me three days ago arrived?" Huang Haojie asked Chen Xiangqian.

Chen Xiangqian nodded and replied, "It's already here." ”

"Take me there."

"Okay, Führer, please come with me."

After a while, the group came to a laboratory, and in a large space, a device similar to a nuclear fusion reactor was standing.

Huang Haojie asked Zhong to take over the supercomputer of this laboratory and began to test the situation of the equipment.

[Master, the equipment is in good condition and ready for experiments.] ］

Huang Haojie turned his head and instructed Chen Xiangqian: "Take 1 kilogram of titanium element." ”

"Okay, I'll arrange it right away." Chen Xiangqian hurriedly went to arrange the titanium elemental material.

Pavlo Korostrov asked with interest: "Did Yuan Xiansheng plan to synthesize radium through nuclear fusion?"

"Exactly." Huang Haojie replied with a smile while entering the parameters to the device.

"Titanium?" Pavlo?? Korostrov touched his thick beard and thought about it, titanium is element 22 with a relative atomic mass of 47.8, while radium is element 88, and the most stable isotope has a relative atomic mass of 226.

If you want to synthesize titanium into radium, then you must go through the No. 44 element ruthenium in the middle, of course, the nuclear fusion reaction can not help but be in place in one step, most likely Mr. 26 element iron, and then step by step.

Pavlo?? Korostrov had previously envisioned combining light elements with heavy elements, but this was too difficult to achieve.

Generally speaking, the artificial synthesis of radium is usually done by bombarding elements heavier than radium by neutrons, so that the core of the heavy element is fissioned into a relatively light radium element.

However, this method has a fatal drawback, that is, the abundance of elements in nature, the larger the element number, the smaller the relative abundance. The abundance of radium is still relatively more, and using heavier elements to make radium obviously outweighs the losses.

After a while, Chen Xiangqian took 10 kilograms of elemental titanium from the experimental material warehouse.

Huang Haojie put 1 kilogram of elemental titanium powder into the reactor through an experimental assistant robot, which is indeed a nuclear fusion reactor.

When the nuclear fusion reaction switch is pressed, the elemental titanium powder in the reaction kettle is crushed by the powerful neutron ionization generated by the NN-8-1 material, and the nuclear fusion reaction begins to occur.

The thermoelectric power generation system and ion power generation system attached to the reactor began to generate electricity, and soon with the output of electrical energy, the titanium atom was fused into iron atoms by the nucleus.

Once the atom reaches the stage of iron, it means that the nuclear fusion reaction begins to enter a dividing line, the nuclear fusion reaction before the iron atom can output energy, and the nuclear fusion reaction after the iron atom shows a negative output state, and the energy must be replenished before the nuclear fusion reaction can continue.

Huang Haojie continued to operate the nuclear fusion reactor, so that the iron atoms in it continued to fuse, under the strong neutron ionization compression, the iron atoms had to yield to synthesize copper nuclei, zinc nuclei, and then from copper nuclei, zinc nuclei to selenium nuclear fusion......

Half an hour later.

The 1 kilogram of elemental titanium in the reactor has been turned into a mixture of 87 element francium, 88 element radium, and a small part of 89 element actinium.

The experimental robot takes a piece of silvery-white metal mixture out of the reactor and places it in a special storage box.

Because whether it is 87 element francium, 88 element radium, or 89 element actinium, these elements are radioactive, especially up to 1 kilogram of quantity, which greatly increases their radioactivity.

"You take this piece of metal and test the specific content of radium." Huang Haojie to Chen Xiangqian and Pavlo?? Korostrov commanded.

"All right, Führer." The two of them hurriedly took the storage box and headed towards the special laboratory.

Huang Haojie looked at the experimental data just now, while checking the element synthesis furnace, this method of synthesizing elements can indeed achieve large-scale production, provided that the energy is sufficient, and it is obviously a very luxurious behavior to forcibly manufacture heavy elements with huge energy.

But now the Human Innovation Alliance has to use this method to make radium, because it is related to the efficiency of the photonic engine.

More than an hour later, Pavlo?? Korostrov ran over excitedly with a test report: "Führer, your experiment is very successful, the content of radium is about 42%. ”

Huang Haojie flipped through the report and asked Pavlo?? Korostrov instructed: "I will leave the elemental synthesis furnace here, and you will produce 50 kilograms of radium as soon as possible." ”

"Yes." Pavlo?? Kolostrov hurriedly agreed, he knew the importance of radium, and before the replacement of beta-ray laser head materials was developed, they could only produce radium in this way at any cost.
