A huge step forward in the quest for nuclear fusion.
France has recently become the epicenter of a historical milestone in nuclear fusion research, thanks to groundbreaking experiments conducted at the European Synchrotron Radiation Facility (ESRF). This monumental achievement, led by First Light Fusion in collaboration with the University of Oxford, places France and its Alpine city at the forefront of the future energy landscape.

What is inertial fusion?
Inertial fusion involves compressing a tiny fuel pellet, usually containing deuterium and tritium, with extremely powerful laser beams. This rapid compression generates a shockwave that implodes the pellet, creating extreme temperatures and pressures at its core—conditions similar to those found in stars. This implosion turns the core of the pellet into a dense plasma where atomic nuclei can fuse, releasing vast amounts of energy.

The role of the Grenoble synchrotron
The Grenoble synchrotron is not just any piece of equipment; it is a marvel of electromagnetic technology used traditionally for high-energy particle acceleration. With a new generation of high-energy synchrotrons, the ESRF stands as the brightest synchrotron radiation source in the world and a hub of excellence for fundamental and innovation-focused research in condensed matter and life sciences.
Europe’s largest pulsed power facility
First Light Fusion is already well-versed in pulsed power technology through its M3 facility, one of the largest such installations globally and the biggest in Europe. With an investment of 4.3 million euros, it is the only machine of its kind dedicated exclusively to fusion research. Using extreme electromagnetic forces, it primarily functions to launch projectiles at the hyper-velocity needed for inertial fusion.
The First Light Fusion and Oxford experiment
Researchers concentrated their efforts on studying shockwaves using specially designed amplifiers to intensify the energy needed to initiate a fusion reaction. These amplifiers, in which First Light Fusion has become a global specialist, were rigorously tested during the experiments at the synchrotron.
Results of the experiment
Thanks to the brilliance and quality of its X-rays, the ESRF, functioning as a “super-microscope,” allowed scientists to observe in detail the propagation of shockwaves inside the amplifiers and through a plastic sample. This precise observation is crucial for validating the performance of the amplifiers and refining the digital models used to simulate these complex phenomena.
A strategic partnership for the future of fusion
The experiment is part of the AMPLIFI partnership, which brings together First Light Fusion, the University of Oxford, and other leading academic institutions. This collaboration aims not only to advance inertial fusion research but also to train the next generation of researchers in this emerging field.
The future following the grenoble experiment
The results from Grenoble are extremely promising and represent a significant step forward in understanding inertial fusion processes. As Francisco Suzuki-Vidal from First Light puts it, these experiments are a giant leap towards mastering fusion. The success of these tests opens new opportunities for future research, aiming to test these technologies at even higher speeds and more extreme conditions. According to Professor Daniel Eakins, the ability to “freeze shockwaves” provides a unique window into their behavior and interaction, a crucial advantage for the future development of fusion amplifiers.
