Fusion, which replicates the same reaction that powers the sun, has long been viewed as an ideal energy source due to its potential to be safe, clean, cheap, and reliable.
Since the early 1960s, scientists have pursued the possibility of using high-powered lasers to compress thermonuclear material long enough and at high enough temperatures to trigger ignition—the point at which the resultant output of inertial fusion energy is greater than the energy delivered to the target.
Scientists achieved ignition in December 2022 at the National Ignition Facility at Lawrence Livermore National Laboratory, but many hurdles remain in making fusion energy technically and commercially viable for mass production and consumption.
Researchers at the University of Rochester's Laboratory for Laser Energetics (LLE) have, for the first time, experimentally demonstrated a method called dynamic shell formation, which may help achieve the goal of creating a fusion power plant.
The researchers, including Igor Igumenshchev, a senior scientist at LLE, and Valeri Goncharov, a distinguished scientist and theory division director at LLE and an assistant professor (research) in the Department of Mechanical Engineering, discuss their findings in a paper published in Physical Review Letters.
"This experiment has demonstrated feasibility of an innovative target concept suitable for affordable, mass production for inertial fusion energy," Igumenshchev says.
