TAE Technologies High-Fidelity Plasma Controls for Plasma Generator: One Step Closer to Clean Fusion Energy Illustration of the TAE Norman (C2-W) fusion device. TAE Technologies (TAE) advances fusion research using Speedgoat real-time target machines including over 400 I/O links as distributed high-fidelity and low-latency plasma controllers. TAE Technologies, the fusion increase plasma performance and further optimized between power research company from temperature. consecutive experiments using the Foothill Ranch, California is Optometrist Algorithm, a joint advancing the field of plasma research partnership between TAE The Challenge physics with their innovative and Google. field-reversed configuration (FRC) A well-known challenge of plasma generator to create a fusion is keeping the plasma The Solution controlled fusion reaction. well centered and away from the confinement vessel walls long Speedgoat delivered the core TAE’s mission is to create and enough to release sufficient functionality and overall commercialize fusion energy that amounts of harvestable fusion acquisition and control system is sourced from a clean, safe, energy. setup, including implementation, and affordable hydrogen-boron for TAE’s Norman. solution for a transformational Early FRCs in the field achieved source of electricity widely lifetimes of no more than a The use of the Simulink® and available in the future. millisecond.
