The Plasma Accelerator

Helion's plasma accelerator raises fusion fuel to 100 million degrees Celsius and directly extracts electricity with a high-efficiency pulsed approach.


Deuterium and helium-3 fuel is heated to plasma conditions. Magnets confine this plasma in a Field Reversed Configuration (FRC).


Magnets accelerate two FRCs to 1 million mph from opposite ends of the 40-foot accelerator. They collide in the center.


When the FRCs collide in the center of the system, they are further compressed by a powerful magnetic field until they reach fusion temperatures of 100 million degrees Celsius.


At this temperature, the deuterium and helium-3 ions are moving fast enough to overcome the forces that would otherwise keep them apart and they fuse. This releases more energy than is consumed by the fusion process. As new fusion energy is created, the plasma expands.

Electricity Recapture

As the plasma expands, it pushes back on the magnetic field. By Faraday's law, the change in field induces current, which is directly recaptured as electricity. This clean fusion electricity is used to power homes and communities, efficiently and affordably.
