Ion Plasmas Simplify Atomic Clocks

Precision timekeeping and the understanding of white dwarf and neutron stars have been made easier through observations of a laser-cooled ion plasma created by researchers at the National Institute of Standards and Technology. Led by physicist Wayne Itano, the team used Bragg scattering of laser light from a cold plasma of trapped beryllium ions to study what previously could be modeled only through calculation -- the crystalline structure of plasmas. "With a large enough cloud -- one made up of hundreds of thousands of ions -- the interior is like a state of bulk matter," Itano said....Read full article
