A particle accelerator is a device for artificially accelerating particles such as protons and electrons.
In this exhibition, we'll introduce everything in a way that's easy to understand, from the basics of particle accelerators to cutting-edge research exploring the mysteries of the universe as well as the results of that research used in familiar places—all while showing what huge accelerator facilities, which we don't usually get a chance to see, actually look like, and including the history of their development.

What is a Particle Accelerator?

Here, we answer everyone's questions: What particles are smaller than atoms? How do you accelerate them? What do you accelerate them for?

Welcome to a Huge Experimental Facility

Some of the particle accelerators used in cutting-edge research are surprisingly huge. What is a large-scale accelerator facility like?

Approaching the Mysteries of Space, Matter, and Life

Atomic nuclei smaller than atoms, even smaller elementary particles…By examining them in detail with accelerators, we can get closer to solving the mysteries of this world.

ROOM2: B3F(Global Gallery)

The Development of Large Accelerators in Japan

Since early on, Japan has worked on the development of particle accelerators and scientific research which uses them. However, the road up to this point has not always been smooth.
