Samples are readied for analysis in an advanced atom probe invented in the 1990s by Thomas Kelly, when he was a professor of materials science and engineering at the University of Wisconsin–Madison. The probes, produced by scientific instrument maker CAMECA in Fitchburg, Wis., can measure the atomic composition of ultra-small samples. The precision instruments are sold around the world to researchers in government, industry and academia.
