It's reasonable for me to have a two-way foil for a second-level civilization, right?

Originally, in his vision, laser weapons could serve as the main output weapons of interstellar wars.

Powerful and fast, this is undoubtedly a weapon for interstellar wars!

But the reality gave him a big hole.

"Professor, we believe that the real use of this laser weapon should be to intercept the kinetic energy weapons fired by the enemy." Wilson reminded softly.

Wilson's words woke up Lu Yongchang.

His eyes lit up, and the scene of zero-controlled electromagnetic cannon firing immediately appeared in his mind.

"that's right……"

Lu Yongchang muttered to himself: "If Ling can control this laser weapon, we can build an interception zone as long as [-] kilometers!"

"Just, what should I choose as the main weapon?"

He frowned and walked slowly towards the seat beside him.

"Professor Lu..."

Seeing Lu Yongchang's "out of his mind" look, Wilson's eyes showed a bit of worry.

Hearing the call, Lu Yongchang raised his hand and waved it casually: "Don't worry, give me some time and let me think about it."

While talking, he sat on the chair and closed his eyes.

There is not much time left for human beings, and he has no extra time to try.

……

In the fluorescent green technology tree space.

Lu Yongchang silently looked at the growing technology tree in front of him.

In the upper left corner of the technology tree, two faint white lights are slowly extending.

[Initial Mastery of Kinetic Energy Weapons: Electromagnetic Coil Gun Technology]

[The prototype of energy weapons: high-energy laser technology]

Two dim cursors gradually light up.

The white spot of light continues to extend upwards.

Until the next dim cursor, the white light spots slowly dissipated.

The cursor is very dim, and even the writing on it is not very clear.

Lu Yongchang stared at the dim cursor and focused all his attention on it.

After the familiar feeling of dizziness, a reminder slowly emerged in his mind.

【Particle beam】

Following the reminder, a strong sense of exhaustion emerged spontaneously from within the body.

He looked up.

There is only one step away from [Initial Control of Energy Weapons], which symbolizes the second-level civilization.

Chapter 228 Range Issues of Ion Beam Weapons

"call……"

Lu Yongchang took a deep breath and opened his eyes.

A strong sense of fatigue came from the depths of his eyes.

This is a hangover from getting "hints".

Although it was a bit uncomfortable, it was much better than the result of being in a coma before.

"professor?"

Wilson's voice came from the side: "Are you all right?"

Lu Yongchang raised his head, looked at Wilson's worried face, chuckled, waved his hands and said, "It's okay."

With that said, he put his hands on his knees and stood up.

"Particle Beam Weapon!"

Lu Yongchang scanned the surrounding researchers, and suddenly said in a deep voice.

"What?" Wilson didn't react for a while, and asked subconsciously.

"Our next research direction." Lu Yongchang said as he walked straight out of the laboratory, "Wilson, follow me."

Watching the gradually receding figure, Wilson was slightly taken aback, and quickly followed up.

……

"Particle beam weapon?" Wilson muttered to himself, frowning as he looked at the holographic image data presented in front of him.

Lu Yongchang on the side nodded and said, "To be precise, it's an ion beam weapon."

"After all, we can't accelerate neutral particles like neutrons yet."

"This is also one of the directions we need to study in the future."

"Just imagine." Lu Yongchang's tone suddenly became a little excited, "If we can manipulate a large number of neutrons, let them strike the enemy ship precisely."

"We can completely bypass the armor and directly attack the personnel inside the enemy ship!"

"Like...a neutron bomb."

Wilson took a light breath.

"Of course, this is just my idea." Lu Yongchang shrugged, with a bit of regret in his eyes, "At present, this technology is still far away from us."

"We can only accelerate charged particles right now."

Wilson pondered for a moment, with some hesitation on his face.

"Professor, I have also learned about weapons in this area before."

"It's just... Compared with lasers, ion beam weapons seem to have a shorter range."

"Because of the dispersion effect, once the ion beam leaves the emitter, it starts to spread out on its own."

Faced with Wilson's doubts, Lu Yongchang nodded with a wry smile: "I know this too."

"But ion beams have many advantages over laser weapons."

"For example?" Wilson's eyes became more suspicious.

"First, long-lasting." Lu Yongchang breathed a long sigh of relief, "On this point, no laser weapon can compare to it."

A wry smile appeared on Wilson's face.

He reached out and touched the tip of his nose in embarrassment, and nodded repeatedly.

As the developer of laser weapons, he is naturally aware of the biggest drawback of laser weapons.

"Second, although the speed is not as fast as lasers, sublight-speed ion beams have advantages that laser weapons cannot match."

The corner of Lu Yongchang's mouth raised slightly, and he continued: "It has quality."

"You can understand it as a weapon that combines the advantages of laser weapons and kinetic energy weapons."

Wilson couldn't help but froze in place.

That's right.

This is the biggest difference between laser weapons and ion beam weapons, and it is also the biggest advantage of ion beam weapons.

E=mc?, the mass-energy formula is destined to carry a lot of energy!

Compared with the attack method of laser weapons burning the surface, ion beam weapons cause damage in a more brutal and weird way!

The specially modulated ion beam can completely "pass through" the armor of the starship and directly strike the internal facilities or personnel of the starship!

In the case that it cannot "pass through" the starship armor, its main damage is similar to that of a laser-it releases a lot of heat and burns through the armor directly!

"Then... what should we do?" Wilson asked with a little shortness of breath.

"It's very simple." Lu Yongchang smiled and stretched out his hand across the air, turning on a holographic projection.

"What we have to do is to reduce its dispersion effect and extend its range."

……

2037.12

In the laboratory, Wilson sighed slightly, and turned off the small particle accelerator beside him.

"Professor, failed again."

Wilson smiled wryly and shook his head: "I think we chose the wrong direction."

"Changing the type of ion is not the right direction for research."

Lu Yongchang didn't speak, but frowned and looked at the experimental data in front of him.

During this time, they experimented with a large number of different kinds of ions, trying to find the one with the least dispersion effect.

At present, the best-performing ions can maintain an effective killing distance of about 500km in space.

This distance is obviously not enough.

However, the experiment is not without any gains.

At least, after so many experiments, Lu Yongchang probably knows what type of ions to choose as "ammunition".

Not protons, not electrons, they are too "light".

heavy ions.

Simply put, it is an ion with an atomic mass greater than that of a helium atom.

Of course, not the "heavier" the better.

On the one hand, the "heavier" the ion, the weaker the dispersion effect and the longer the range.

On the other hand, the "heavier" the ion, the more energy it consumes for acceleration, and the slower the ion beam speed, the resulting killing effect will even decrease rather than increase.

In addition, light ions are more likely to penetrate starship armor and cause damage to the interior, while heavy ions are more likely to cause damage to starship armor.

This requires them to find a balance in the middle.

"Tsk..."

Lu Yongchang clicked his tongue a little irritably.

There are too many things to consider, and more importantly, they have not solved the most basic problems.

Range problem!

You can't put your face on the output at that time, can you? !

Just when Lu Yongchang was restless, a holographic image of Zero suddenly appeared.

"Professor, there is one thing I need to remind you."

Lu Yongchang, whose train of thought was interrupted, looked impatiently at Ling.

He frowned and asked, "What's the matter? If it's not something important, you can just go to Fang Xu."

Zero's tone did not fluctuate at all, and he said flatly: "Professor, in a week, the sun will completely swallow Mercury."

"..."

In the laboratory, it fell into silence again.

Wilson stared at Zero's hologram in horror.

Although it is known that this is an inevitable phenomenon in the solar red giant process, but...

When things really happened, Wilson had to admit that the news was still too shocking for human beings.

Lu Yongchang sighed forcefully, reached out to rub his cheeks, and stood up from his seat.

"Time flies so fast..."

"Zero, you can start preparing various protective measures." Lu Yongchang said in a deep voice, "Also, monitor the conditions of Mercury and the sun at all times."

"receive."
