Next to my ears, there was a click-click sound, as if the sound of a Geiger counter was ringing...
Grete really wanted to escape from the room immediately, get himself a lead coat, and then take out a Geiger counter to test it. He tried to calm down for a few moments before he regained his train of thought:
Don't be too nervous, X-rays are not the only ones that can penetrate wood and stones, but will be blocked by lead. X-rays are not the only ones that can see bones through the body...
At least, the first application he developed when he just traveled through time, using [Detection Magic] to see bone structure, had similar properties...
Grete took two deep breaths and tried to calm down. He tentatively asked Cerela:
"The ray you created can be seen if you use magic, um, for example [detection magic]?"
"What?"
Miss Yinlong opened her eyes wide in surprise:
"Why do you need to use [Detection Magic] to see? I can see it directly! Oh, okay, I'll try again..."
She raised her hand for the second time. Grete jumped away suddenly:
"Don't point it at me! No, don't point it at other people! Serira, remember, never point this ray at people unless you have special needs!"
"Oh... Okay." Cerela replied sadly, and the tips of her ears tended to droop a little. She turned in one direction, ensuring that her palms were aimed at the wall, and turned to look at Gretel:
"Are you ready? One, two, three!"
Gretel opened his meditation field of vision at the right time. The field of vision was empty and there was no sign of anything lighting up. He looked at Serrela inquiringly, and Serrela also shook her head:
"It's better to see clearly directly, using meditation vision, tsk..."
Okay, then, it seems that the ray created by Cerera and the magic feedback seen by [Detection Magic] are not the same thing at all... As for how to determine whether the ray created by Cerera is an x-ray...
…
"Mr. Norwood!" Grete once again called the transformation mage in the mage tower, the omnipotent Party B, the fifth-level mage Mr. Norwood:
"Do me a favor and get a high-voltage vacuum tube..."
For the purpose of artificial X-rays, Gretel specially set aside a room on the bottom floor of the Mage Tower, next to the morgue.
Master Norwood was responsible for shaping the glass tube, installing a spiral-shaped fine gold wire on one end that seemed to have properties closest to tungsten, and a fine gold sheet on the other end;
As a magician of the plasticity department, Aurora was responsible for vacuuming the glass tube as much as possible, and then asked Master Norwood to seal the glass tube;
Then, Master Norwood connected the adamantine wire to the wires in the wizard tower, making it hot and red. Aurora was eager to try and grabbed the wires connected to both ends of the vacuum tube:
"Just discharge it, right? Just discharge it, right? Let me give it a try."
"etc!"
Gretel raised his hand. The two invisible servants in the wizard's tower worked together to move a box of lead sheets. Master Norwood used his mental power to quickly shape the lead sheet and shield it between the vacuum tube and everyone. Gretel then
He breathed a sigh of relief:
"Okay. Would you like to try it?"
Aurora closed her eyes and concentrated. Lightning flashed from her fingertips and poured into the glass tube through the wires. At the same time, she turned her head to the right and looked at Cerela hopefully.
Serira revealed one eye from behind the lead sheet and stared at the vacuum tube. After looking at it for a while, she shook her head very firmly:
"I didn't see it at all!"
"this"
Grete was wiping sweat on the side. This research method of rubbing vacuum tubes with hands and manually discharging electricity, no matter how many times I have seen it, I still feel that I am not used to it...
But the vacuum tube discharge should be correct. Every step should strictly follow the description in "Medical Physics":
The vacuum tube heats the cathode to release hot electrons, and then applies high-voltage direct current to the anode and cathode of the vacuum tube, causing the cathode's electron flow to hit the anode target, causing the target to emit x-rays...
Is the vacuum tube not properly evacuated?
Or, is the high pressure not enough?
Or maybe the cathode isn't burning hot enough to release enough hot electrons?
Gretel led everyone to repeatedly revise the experimental design. Increase the current, heat the cathode metal wire, and then heat it again. [Dark Vision] The images seen become increasingly redder and redder, and finally, red can also be seen with the naked eye, and then
"Snapped!"
The wire burned and the vacuum tube exploded...
Well, it seems that the vacuum is not enough, otherwise it will not burn. Gretel, please Aurora, make the vacuum tube empty a little more, and then empty it a little more
"Snapped!"
The vacuum tube is broken...
"This... thicken the wall... make the glass tube stronger... Mr. Norwood, please..."
"Snapped!"
If you smoke it again, it will break again.
Relying on the method of adding more water when there is more noodles, and adding more noodles when there is more water, Grete finally got a glass tube that exhausted Aurora's mental power and could not be vacuumed any more. Then, he turned on the electricity and heated the fine gold wire until it could no longer be vacuumed.
hot:
"Aurora, power on"
Aurora Wharton struggled to mobilize her mental strength.
The fingertips of this evocation mage, who was already at level six and was striving to sprint towards level seven, had unprecedented brilliant lightning dancing on his fingertips.
Even the brilliant blond hair that had not been cut short for a long time exploded in the electric light. At a glance, it looked like a lion with fried hair, oh no, like golden hair...
If Grete had a camera and was in the mood, he would definitely take a picture of the scene in front of him. But he was not in the mood at all now. He just looked at Cerela expectantly, waiting for the eldest lady to give her answer:
"Hmm... It seems there is a little bit, but not much. It's less than the bit illuminated by the star dome. If you don't pay attention, you can't really see it..."
"Then what should we do? Grete, which direction still needs improvement?"
In the basement, two magicians and a silver dragon stared at Gretel. Gretel scratched his head:
"So...is it still a problem with the voltage? The voltage needs to be a little higher..."
In my impression, the high voltage applied between the Yin and Yang poles of a medical X-ray machine seems to be tens to hundreds of kilovolts...
"I can't help it anymore!" Aurora screamed. He couldn't go any higher! If he went any higher, his mental strength wouldn't be able to hold on anymore!
"You don't need to." Grete shook his head. To increase the voltage, there are two ideas: one is to get a transformer to increase the voltage from 220 volts to 220 kilovolts; the other...
Looking for the Lord of Thunder?
Sin, sin, that's the teacher, not the human flesh generator...
Of course, the Lord of Thunder is in seclusion and cannot be delayed for the time being. Gretel changed his mind and directly approached Human Generator No. 2, the senior sister who studies electromagnetic direction, Archmage Philbi:
"Senior sister, please help me! Cerela has discovered something strange, and we are trying to reproduce it... It is a strange ray in the sun, which may be related to the plasticity system!"
