Research by scientists at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and collaborating institutions has the potential to improve plasma performance in tokamak nuclear fusion reactors, according to a recent paper in Nuclear Fusion. The research focused on the use of a PPPL-developed dropper to apply coatings of boron powder to the tungsten components inside a tokamak, thereby helping protect the tungsten against the intensely hot plasma. According to lead author Grant Bodner, this process offers “a way to deposit boron coatings without turning off the tokamaks’ magnetic field.”

Research led by scientists at the Department of Energy's Princeton Plasma Physics Laboratory (PPPL) provides new evidence that particles of boron, the main ingredient in Borax household cleaner, can coat internal components of doughnut-shaped plasma devices known as tokamaks and improve the efficiency of the fusion reactions, according to an article published on Phys.org on April 2.
