Early Japanese accelerator used in particle and nuclear research

Cockcroft–Walton accelerator

This is a section of an early accelerator built by Osaka Imperial University (now Osaka University) in 1934. Accelerators are experimental apparatus for research into elementary particles and atomic nuclei. Atoms(Ions) such as hydrogen were accelerated in this apparatus at a very high voltages on the order of 600,000 V. The accelerated Ions were then collided with other materials to study the properties of nuclei. Osaka University has been a major center of nuclear and elementary particle research before and after the World War II, including the period when it was Osaka Imperial University. Osaka University is currently conducting cutting-edge research in this field. It is also worth noting that the research for which Dr. Hideki Yukawa won the Nobel Prize was conducted at Osaka Imperial University in the 1930s.
