During the ITER Private Sector Fusion Workshop in May, Melanie Windridge moderated the panel on inertial confinement fusion with Kazuki Matsuo, the CEO of the Japanese startup Ex-Fusion (which plans to build a laser-powered commercial fusion reactor), and Dan Gengenbach, CEO of the German startup Marvel Fusion (which is pursuing laser-driven fusion through a public-private partnership with Colorado State University in the United States). Part of the discussion was about how inertial and magnetic confinement initiatives can learn from one another.
Fusion historians look back at the 1950s as an age of optimism in the nuclear field. Scientists, infused with a belief that controlled fusion "could be mastered by short-term technological pressure just as uncontrolled fusion had been,"¹ identified magnetic confinement as the method by which fusion power would be achieved. Around the world, scientists embarked on a variety of magnetic fusion concepts, from tokamaks to stellarators to mirror configurations. As the first fission power plant began operations in 1957, fusion scientists hoped that they would not be far behind.
