A still shot from the Senate ENR Hearing to Examine Fusion Energy Technology Development.
Hours before the Senate Committee on Environment and Natural Resources (ENR) opened a scheduled September 19 hearing on fusion energy technology development, CNN published an article titled “The US led on nuclear fusion for decades. Now China is in a position to win the race.” The article was entered into the hearing record, but senators had already gotten the message.

Start talking about dust in a vacuum, and some people will think of household chores. But dust has featured in recent nuclear science and engineering headlines in curious ways: ITER is deploying oversized dust covers inspired by space satellites in the south of France, while at Yale University, researchers have watched every move of a dust-sized particle levitating in a laser beam for telltale twitches that indicate radioactive decay.

The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory has achieved fusion ignition at least five times, each time by directing its 192 high-powered lasers on a capsule containing a tiny, 2-millimeter target filled with hydrogen fuel. Not every shot achieves ignition, however. Tiny imperfections in the targets can mean fizzle, not fusion. But each of the targets used in successful experiments to date have something in common: they were characterized and selected by the 4Pi Integrated Metrology System, a new measurement system developed by General Atomics. Now, the team behind that system is being recognized.
GA announced last week that its Metrology Research and Development team had won the 2024 "Team of the Year" R&D 100 Professional Award from R&D World. The magazine that each year announces the R&D 100 awards that have been dubbed the “Oscars of Innovation” also selects just one “Team of the Year” and announces that award together with four other professional awards.

JT-60SA (Japan Torus-60 Super Advanced) is the world’s largest superconducting tokamak device. Its goal is the earlier realization of fusion energy (see Fig. 1). Fusion is the energy that powers the Sun, and just 1 gram of deuterium-tritium (D-T) fuel produces enormous energy—the equivalent of 8 tons of crude oil.
Last fall, the JT-60SA project announced an important milestone: the achievement of the tokamak’s first plasma. This article describes the objectives of the JT-60SA project, achievements in the operation campaign for the first plasma, and next steps.

Japan’s recent moves to boost fusion power in the nation’s energy plan and accelerate the timeline for a prototype fusion power plant come in response to increased global attention on fusion energy. Even as ITER faces delays, more than 40 private fusion developers are pursuing different technologies and competing for attention. And so are other countries, including the United Kingdom, which announced its plans for a fusion pilot plant back in 2019. Fusion companies and nations alike are responding to a growing sense that there is a race—or at least collective momentum—to commercialize fusion energy.

The magnetic mirror fusion concept dates to the early 1950s, but decades ago it was sidelined by technical difficulties and researchers turned to tokamak fusion in their quest for confinement. Now it’s getting another look—with significantly more powerful technology—through WHAM, the Wisconsin HTS Axisymmetric Mirror, an experiment in partnership between startup Realta Fusion and the University of Wisconsin–Madison.

It was a laser shot for the ages. By achieving fusion ignition on December 5, 2022, Lawrence Livermore National Laboratory proved that recreating the “fire” that fuels the sun and the stars inside a laboratory on Earth was indeed scientifically possible.

At the 34th ITER Council Meeting, held June 19–20, ITER director general Pietro Barabaschi reported on ITER’s progress and presented an updated baseline proposal that would “prioritize the start of substantial research operations as rapidly as possible.”
