Fusion codes and standards | Award for ITER Japan s Hideo Nakajima
Hideo Nakajima, a senior engineer at ITER Japan, has received an award from the Japan Society of Mechanical Engineers (JSME) for his contribution to the development of codes and standards for fusion facilities.

Mr Nakajima is the latest recipient of the JSME Codes and Standards Award for International Achievement for his contribution to rules for superconducting magnet structures.The JSME Codes and Standards Award for International Achievement recognizes outstanding contributions to international exchange, the improvement of international codes and standards, and the development of standardization activities in Japan. The ultimate goal of JSME s
The term atomic clock may conjure up scary, 1950s-horror movie mental images: A Doomsday device, constructed by a lab coat-wearing maniac in a mountain fortress, is ticking away the seconds before it wipes out our entire planet. In reality, though, atomic clocks are one of the more benign inventions to emerge from the explosion oops, maybe not the best word choice of knowledge about the workings of the atom and its parts. That knowledge came in the wake of the World War II Manhattan Project to develop the atomic bomb.
Unlike the bomb, though, atomic clocks don t split atoms and they don t blow up. Instead, they use oscillation that is, the change in the flow of electrical charge in between an atom s nucleus and its surrounding electrons, the same way an old-fashioned grandfather clock might use a pendulum. Because an atom s oscillation involves incredibly small units of time a cesium atom, for example, has a frequency of 9,192,631,770 cycles per second and is extraordi
