Fusion's Hidden Problem: Sensors That Can Survive 100M Degrees

What Happened A comprehensive new report sponsored by the U.S. Department of Energy has identified a critical technology gap that could hamper the commercial deployment of fusion power: the lack of advanced diagnostic tools capable of operating in extreme fusion environments. The report, which brought together 70 experts from universities, national laboratories, and private industry, pinpointed seven priority research areas for fusion plasma diagnostics. These range from measuring burning plasma conditions to developing sensors for full-scale pilot plants.
