Aberdare-born Dr Lyn Evans told the Western Mail this week that the achievement at the 17-mile circular particle accelerator
buried beneath the Franco-Swiss border, was a "major breakthrough".
Oganessian and his colleagues of JINR accelerated neutron-rich calcium-48 ions in a circular particle accelerator
and then steered them into a spinning, saucer-size ring of americium-coated titanium foil.
A Japanese research team has developed the world's first technology to dramatically boost the performance of synchrotrons, circular particle accelerators
used in experiments to find out more about subatomic particles, a team member said Friday.
