“What we study is thinking about new technology that would be a way to start up future fusion devices. And it’s really looking at, how do you reduce the cost and complexity,” said Steffi Diem, an assistant professor at UW-Madison and principal investigator of the Pegasus Three experiment. “And our technology looks at building. It looks kind of like a small lightsaber that injects, you know, the fuel in it, and then we capture it by a magnetic field.”
