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
