Helion

We’ve raised a $465 million Series G funding round at $15.5B post-money valuation to accelerate the commercial deployment of fusion. Read more here: helionenergy.com/newsroom/he…

POV: You’re walking through the world’s first fusion power plant.

@APSphysics Division of Plasma Physics here we come! The Helion crew will be presenting talks and posters throughout the week. A preview of what's to come: Eric Clark | Presentation 🖥️ Adaptive time-integration schemes that let us simulate the full FRC compression stroke over millions of steps while keeping energy conservation under control. Prabhat Kumar | Presentation 🖥️ A novel energy-conserving implicit algorithm for hybrid PIC simulations that avoids numerical heating, built for trustworthy long-timescale modeling of FRC formation, merging, and compression. William White | Presentation 🖥️ 3D simulations of two FRCs colliding and merging, revealing instabilities that 2D models miss. Ria Meston | Poster 🪧 Plasma-material interaction in irradiation-damaged silicon carbide, informing design limits for the electrically insulating materials that make direct energy recapture possible. Colin Swee | Poster 🪧 Modeling how silicon impurities change X-ray emission, so we can measure electron temperature on our machines reliably and on fast timescales. If you're at APS DPP, come find us!

Helion has been recommended for @ENERGY INFUSE funding, in partnership with Princeton Plasma Physics Laboratory's FLARE facility, to study reconnection physics in field-reversed configurations. This work will improve our understanding of plasma transport and strengthen the predictive models used to design future fusion systems. Full announcement: energy.gov/science/articles/…

How do semiconductors power fusion? Director of Engineering Manav Singh explains how Helion is reengineering SCRs (thyristors) to shape, compress, and recover energy from fusion plasmas.

Helion has been awarded $175 million in funding from the U.S. @CommerceGov through the CHIPS Research and Development Office to build new semiconductor manufacturing and advanced-packaging capabilities in the U.S. helionenergy.com/newsroom/he…

Unlimited clean energy on the horizon.

Meet Jack, a firmware engineer at Helion. Jack helps bridge the gap between hardware, software, and machine operations.

A construction feat: beams spanning more than 224 feet without intermediate columns. Once fully assembled, the generator hall will be about the size of one and a half football fields, end zone to end zone.

Does fusion produce radiation? Yes. So do many things we encounter every day. Learn how radiation works and why it's an important part of fusion science: helionenergy.com/blog/does-f…

Helion's plasma really is pink. But what makes it appear that color is more complex than what our eyes can detect. Read the science behind the glow: helionenergy.com/blog/why-is…

First vacuum pump down on Tiny Merge complete! The team reached the machine’s target base pressure of 1x10-6 torr in under an hour, allowing the team to verify that the machine can achieve high vacuum before additional hardware is installed.

How do you build and scale up technology that has never existed before? Meet the Demonstrator Circuit Unit: a testbed for validating the hardware, manufacturing approaches, and system-level performance needed for commercial scale fusion.

Behind the scenes of building the Tiny Merge compression section.

Making moves! Tiny Merge’s compression section has made its way from production floor to machine, bringing us one step closer to machine operations.

‘Twas the night before lift day...

Carina, our full fabrication and machine shop, serves as both an R&D lab and production floor. From Swiss screw machines to Puma 2600 lathes, we’re adding the capabilities to manufacture fusion power plants from the ground up.

In 2022, we opened Carina, our machine shop. Since then, we’ve added more machines, more machinists, more engineers, and more capability.
