About Institute of Particle and Nuclear Studies

“Where Do We Come From? What Are We? Where Are We Going? ” Paul Gauguin(France) 1987.

The IPNS in KEK is conducting research on particles, nuclei which constitute the universe, and cosmology from both theoretical and experimental perspectives.

Through such research, we are tackling the three ultimate mysteries of humankind, which the French painter Paul Gauguin also raised in his painting.

Research Center

There are three campuses in Tsukuba, Tokai,and in Wako Nuclear Science Center (WNSC) as our main bases in Japan.

IPNS also works with the European Organization for Nuclear Research (CERN), the Paul Scherrer Institute (PSI) in Switzerland, TRIUMF in Canada, the Atacama Highlands in Chile, and so on.

Tsukuba Campus (Tsukuba, Ibaraki)

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

We also have the B-factory facility to search for New Physics. 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 measuring with higher precision, we aim to discover new laws of physics.

Tokai Campus (Tokai, Ibaraki)

An experimental facility that utilizes the high-intensity proton accelerator called J-PARC. For example, the Neutrino Experimental Facility for neutrino study, the Hadron Experimental Facility for researching the inner structure of nuclei with various hadron beams and the decay process of the K mesons, and the Materials and Life Science Experimental Facility (MLF) for measuring muon’s property very accurately.

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, we aim to elucidate the mechanism of the early universe of nucleosynthesis.
