'The Black Fuzz That Decides When Fusion Arrives

Polished tungsten went into a low-energy helium plasma in Japan in the mid-2000s and came out velvet black — grown over with a forest of nanoscale tendrils, more than 90% empty space, that nobody had predicted. The field calls it fuzz, and it appears on the exact component fusion power plants depend on: the tungsten armour facing the plasma. The stranger result came in 2009, when two independent groups — Miyamoto, Nishijima and Ueda on PISCES-A at UC San Diego, and Alimov, Shu and Roth working between JAEA and IPP Garching — showed that seeding a deuterium plasma with a few percent helium suppressed hydrogen blistering completely, at fluences up to 1×10²⁷ D m⁻².
