The company's small reactor core, called Jyn, is only five inches in diameter and has been iterated 25 times since last fall. While no fusion reactor has yet produced net energy, this milestone puts Avalanche on a credible path toward ignition conditions. The results were validated by an MIT plasma physicist but have not yet been peer-reviewed. ## Full article daily.dev links to this article rather than hosting it.
