In an underground vault enclosed by six-foot concrete walls and accessed by a rolling, 25-ton concrete-and-steel door, University of California, Berkeley, students are making neutrons dance to a new tune: one better suited to producing isotopes required for geological dating, police forensics, hospital diagnosis and treatment. To create neutrons in the high flux neutron generator, UC Berkeley researchers heat up deuterium atoms in a vacuum chamber to 50,000 degrees Celsius to obtain an ionized p
