Advanced Target Design
First Light Fusion uses its structured and high-dimensional targets to achieve a tailored delivery of energy - the design of which can be tuned depending on the physics goal.
Two distinct applications of First Light’s advanced targets are for achieving high-gain inertial fusion using a pulsed power driver, and for studying the properties of materials at extreme conditions.
Both designs can be efficiently optimized using machine learning and data science-based simulations tools developed in-house to then be crafted by our precision manufacturing facility.
Demonstration of Amplifier Targets
First Light Fusion’s advanced targets for material science applications are called “Amplifiers”. They are compatible with both two-stage light gas gun and pulsed power drivers, and have been successfully used across several experimental facilities worldwide.
At our First Light two-stage gas gun facility in the UK, an amplifier achieved a pressure of 25 million atmospheres - 12x higher pressure than what is typically achievable using these drivers in July 2025.
Similarly, an amplifier designed for use on the Z Machine at Sandia National Laboratories in the U.S.A. (the largest pulsed power machine in the world), achieved a pressure of 37 million atmospheres - more than doubling the previous record for pressure achieved on this platform.
Precision Manufacturing
We have developed and honed sophisticated, cutting-edge precision manufacturing methods and capabilities which have been crucial to the research and manufacture of our high-precision components and targets.
Our experienced team of technicians and engineers produce parts to micron-level accuracy using advanced techniques developed specifically for our fusion approach. This is done in our state-of-the-art, temperature-controlled machining facility where the components are also inspected using the latest optical, laser and tactile metrology.
Every target is custom-designed, often requiring never-before-made geometries and materials and ultra-fine tolerances. What sets our manufacturing apart is that all is done in-house, including the intricate and precise fabrication of every component assembly.
We manufacture with extreme precision to ensure every test delivers clean, reliable data and rapid iteration. With in-house capability, we move fast from simulation, design and manufacture to build and test - accelerating the pace of fusion R&D.
