Researchers at the University of Michigan, Ann Arbor, Los Alamos National Laboratory, Idaho National Laboratory, Idaho Falls and TerraPower based in Bellevue, Washington, have demonstrated the power of high-energy beams of charged particles (ions). The ions can rapidly and consistently damage samples of ferritic-martensitic steel, the material used in certain nuclear reactor components. The significance of the result is that the breakdown closely replicates that seen when high-energy neutrons from a nuclear reactor interact with the material - damage accrues in a matter of days, rather than decades.
