About IPNS

KEK’s IPNS (Institute for Particle and Nuclear Studies) is a national institute for particle and nuclear physics in Japan. We carry out comprehensive studies on particle physics, nuclear physics, and astrophysics using both theoretical and experimantal approaches.

Physicists at IPNS are seeking answers for fundamental questions of the Universe and Life : What are we made of ? What is the universe made of ? How did it start ?

Physicists also work together with foreign institutions as well.

Research Center

Tsukuba Campus ( Tsukuba, Ibaraki)

We have one of the largest theoretical center in the world. We cover all particle, nuclear theory and cosmology.

We also have the B-factory facility to search for New Physcis. The Belle II experiment reproduces the state of the early universe using the SuperKEKB accelerator. By collecting large amount of data than ever before and measurement with a higher precision, we aim to discover new laws of physics .

Tokai Campus ( Tokai, Ibaraki)

An experimental facility which utilizes the high intensity proton accelerator called J-PARC.

There are various experiments going on. See J-PARC for details.

Wako Nuclear Science Center (WNSC) ( Wako, Saitama)

Wako Nuclear Science Center was established in 2015. It is located inside RIKEN Nishina Center .

By examining the nature of the neutron excess heavy short-lived nuclei using KISS (KEK Isotope Separating System) instrument, we aim to elucidate the mechanism of the early universe of nucleosynthesis. In addition, we also applied research using the short-lived nuclei.
