PNNL scientists are searching for a rare form of radioactive decay—never before detected—called neutrinoless double-beta decay. Drawing upon the Lab’s signature capability in ultra-low-level counting, their research could help determine the mass and properties of neutrinos, one of Nature’s fundamental sub-atomic particles. The copper used to build and shield the experiment will be manufactured underground in an ultra-pure form using a PNNL-developed technology to protect against naturally occurring radioactive impurities. Shown here, copper is deposited on stainless steel mandrels, machined and used for construction of gas proportional counters. The blue solution in the background is copper sulfate from the electroforming bath in which these copper pieces were grown.
