New Tiny Crystal Sensor Measures Extreme Fusion Magnetic Fields

Researchers at Sandia National Laboratories have developed a miniaturized, laser-based crystal sensor capable of tracking intense magnetic fields within extreme environments, including fusion plasma and high-radiation zones. The device, which uses rare-earth garnet crystals like TSAG and TGG, provides stable, high-precision measurements where conventional metallic sensors typically fail or degrade. Overcoming Limitations in High-Energy Environments … Read more

Scientists May Have Solved Two of Fusion Energy’s Biggest Problems at Once

Taming the Star: How New Plasma Breakthroughs are Fast-Tracking the Fusion Era For decades, nuclear fusion has been the “holy grail” of energy—a promise of limitless, clean power that mimics the very process fueling the sun. But there has always been a catch: the “star” we are trying to build on Earth is incredibly temperamental. … Read more
