Safeguarding fusion with a tungsten shotgun

Los Alamos National Lab blasts runaway electrons with tungsten particles to prevent fusion damage.

Harnessing the energy of stars is no simple feat – scientists have been "20 years away" from the successful attainment of sustained nuclear fusion for more than five decades. A Los Alamos National Laboratory discovery that utilizes a "tungsten shotgun" to neutralize destructive instability in fusion...
