The Dude

Machinist Randy Hughes works in the world’s deepest clean-room machine shop, nearly a mile underground in the Sanford Underground Research Facility. He is fashioning parts for the MAJORANA DEMONSTRATOR experiment, using the world’s purest copper. The machine shop is underground to avoid contamination by the cosmic radiation that rains down on the surface of the earth. Photo credit: Matthew Kapust.
