Tungsten Degradation (IMAGE) DOE/Oak Ridge National Laboratory Caption A study led by Oak Ridge National Laboratory subjected tungsten to low energies, akin to normal operations of a fusion reactor (left), and high energies emulating plasma disruptions (right). The study provides new knowledge needed to design robust fusion materials.
