In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have shown how two old methods can be combined to provide greater flexibility.
While the two methods – known as electron cyclotron current drive (ECCD) and applying resonant magnetic perturbations (RMP) – have long been studied, this is the first time researchers have simulated how they can be used together to give enhanced plasma control.
“This is kind of a new idea,” said Qiming Hu, a staff research physicist at PPPL and lead author of a new paper published in Nuclear Fusion about the work, which has also been demonstrated experimentally. “The full capabilities are still being figured out, but our paper does a great job of advancing our understanding of the potential benefits.”
