Out today: How to engineer a renewable deuterium-helium-3 fusion fuel cycle from Fuel Cycle Team Manager, Dr. Lily Hale: helionenergy.com/articles/how-t…

This is what a high-throughput hardware lab sounds like Our Electrical Engineering team delivered more than 70,000+ custom circuit board assemblies for Polaris in 2024, comprised of over 9 million individual electronic components – 3x the number of electrical components on board

Cable assembly and plug in was the largest schedule driver for previous prototypes. We took those learnings and streamlined installation by bundling pre-cut cables and assembling them in trays, making installation process faster and more efficient—enabling rapid bring-up for

deploying fusion to the world is surprisingly gated on high-power semiconductors. the most important place you could design and build those high-power semiconductors (and do other awesome electrical engineering) is helion. please consider: job-boards.greenhouse.io/helionenergy/j…

We're applying basic electrical engineering principles to making fusion electricity, resulting in fewer parts, fewer losses, and a more direct path to getting fusion on the grid. Read more from Senior Manager of Electrical Engineering Manav Singh: helionenergy.com/articles/helio…

As we’re operating Polaris, we’re already seeing the largest-ever FRCs we (or we believe anyone else) have seen before!

Today is an important day for fusion, thanks to legislation coming from WA! HB 1018, signed into law this morning, clarifies the permitting pathway for fusion in Washington, ensuring fusion has the same permitting optionality as all other clean energies in the state.

Integrating over 700 miles of cable in Polaris:

We use CVD diamond detectors to measure fusion performance. Diamonds detect neutron-carbon interactions with high speed, energy resolution, and high-level radiation resistance, enabling us to track fusion yield, confinement time, and ion temperature in our machines.

This week, we welcomed our first-ever intern cohort at Helion! They'll spend the summer building fusion and helping us deliver on our mission - let's go!!!

Fusion may still sound like science fiction— but it might not be for much longer. With AI pushing demand for clean power to new highs, a breakthrough may finally be close. For Decoded, Gustaf Alströmer traces the history of fusion, the physics behind it, and the engineering challenges

Filling the racks

We’ve brought one of several new winding machines online to increase our high-voltage pulsed capacitor production. These new machines improve film winding consistency and support higher throughput for larger form factor designs.
