2. Exploring the Secrets of Matter: Accelerator Science


Accelerators are large-scale experimental facilities for use in elementary-particle physics and other fields relating to the exploration of the basic structures of matter and the forces that operate between those structures. In recent years there has been dramatic progress in these areas.

Experimental research is underway at large-scale accelerator facilities in Europe, the United States, and Russia. Research in Japan, which is led by the National Laboratory for High Energy Physics, is also among the most advanced in the world ( Table II.6.7). At present the laboratory is conducting experimental research on particles using an accelerator nicknamed TRISTAN (Transposable Ring Intersecting Storage Accelerator in Nippon), which has a circumference of approximately 3 kilometers and can produce collision energy of 60 billion electron-volts. In fiscal 1994 the laboratory began to implement the TRISTAN II (B Plant) plan, which aims to open up new horizons in elementary-particle physics.

The synchrotron radiation apparatus facility at the National Laboratory for High Energy Physics is the world's biggest and most advanced light source for synchrotron radiation. It is used extensively in university research and industrial research and development to explore the world of molecules and atoms. The laboratory's proton accelerator is used in proton-beam cancer therapy and is also a powerful research tool.
