AboutAbout the lab
Exploring the flow of energy inside a fusion reactor
Fusion Energy Dynamics (FED) belongs to the Laser Fusion Science Division of the Institute of Laser Engineering, and studies how energy moves inside a laser fusion reactor.
Part of the energy generated by fusion reactions circulates through the reactor as energy and as fuel, changing form along the way.
The challenge is to build a laser fusion reactor system that satisfies both of these at the same time.
The lab works on blankets, fuel production, digital twins, and reactor design.
Key terms
- Blanket
- A component of a fusion reactor that converts fusion energy into heat, electricity, and other forms, and at the same time produces fuel.
- Digital twin
- An approach that builds a reactor in virtual space and models each of its components so that trial and error becomes possible.
- Laser fusion
- An approach that triggers fusion using lasers. High-purity fuel is supplied to the reactor in solid form.
ResearchResearch themes
Toward the use of fusion energy, the lab studies how energy moves within the system of a laser fusion reactor. The challenge is to build a reactor system that sustains both energy and fuel at the same time.
*Illustrative imageBlanket Research
A blanket is a component of a fusion reactor that converts fusion energy into heat, electricity, and other forms while also producing fuel. Aiming for implementation in laser fusion reactors, the lab studies blanket materials and configurations.
*Illustrative imageResearch on Fuel Production Technology
In a laser fusion reactor, high-purity fuel is supplied in solid form. Through experiments and simulations, the lab investigates the whole process, from efficiently recovering the fuel produced in the blanket and removing impurities, to supplying it to the target.
*Illustrative imageDigital Twin of the Reactor
To build a laser fusion reactor in virtual space, the lab is modeling each component of the reactor. For blankets, which have not yet been tested in experiments using fusion reactions, it aims to improve the accuracy of their functions through trial and error in virtual space.
*Illustrative imageLaser Fusion Reactor Design
Reactor design is a way to clarify the research challenges that must be addressed to realize a laser fusion reactor. The lab has completed the design of a laser fusion research reactor driven by a megawatt-class laser that can be built with current technology, and will next work on the design of a commercial reactor.
