Lü Yongchang immediately turned the knob to slowly increase the current.
When they saw the resistance value on the instrument screen remain perfectly unchanged, all the researchers in the laboratory let out a soft gasp of surprise.
Unlike the researchers around him, Lü Yongchang's expression remained very solemn.
The test is not over yet.
He also needs to test the material's performance in low-pressure environments!
Lu Yongchang winked at Fang Xu, who was standing to the side.
Fang Xu nodded slightly and turned on the vacuum pump next to him.
With a low humming sound, the air inside the glass enclosure was gradually drawn out.
As the barometer readings slowly decreased, even Lü Yongchang broke out in a cold sweat.
It's important to know that superconducting materials react extremely violently to environmental changes!
In the past, superconducting materials would lose their superconducting effect if there was even a slight change in temperature or pressure!
Under the influence of such a powerful current, once the superconducting effect of the wire disappears, even if the resistance value is very small, it will instantly generate extremely powerful heat.
The consequence, naturally, was that this currently unique room-temperature superconducting wire would melt and break!
Several tens of seconds later.
Looking at the calm resistance curve on the test instrument screen, Lü Yongchang finally broke into a bright smile.
He gently wiped the sweat from his forehead, raised his right hand high, and shouted, "Success!"
"We did it!"
Fang Xu, his face flushed with excitement, shut down one instrument after another, then rushed to Lü Yongchang's side and patted him hard on the shoulder: "Well done!"
"We have room-temperature superconducting technology, Academician Fang. Now we should start preparing for the modification of the stellarator!" Lü Yongchang quickly snapped out of his elation and said in a deep voice.
Fang Xu nodded excitedly.
"I'll go and inform the lab staff right away. We'll start modifying the stellarator this afternoon!"
