At J-PARC, a proton beam is accelerated to a world-class high-energy beam by a series of accelerators, which consists of
The high－energy beam is delivered to three different experimental facilities for conducting cutting-edge research in the fields of materials and life science, and particle and nuclear physics.

At the 50GeV Synchrotron, nuclear and particle physics experiments are performed using high-intensity beams such as the kaon beam, pion beam, neutrino beam as well as the primary proton beam.
In these research fields one looks for answers to the very fundamental questions such as; " What are the extreme constituents of matter? ", " What are the fundamental interactions or forces acting between particles? " In order to study these questions, the experiments with high precision, with very new phenomena or with exotic states will be pursued using high-intensity beams.

Materials and Life Science Experimental Facility (MLF) aims at promoting materials science and life science using the world highest intensity pulsed neutron and muon beams produced by using 3 GeV protons with a current of 333 micro-amps and a repetition rate of 25 Hz.

The proton beam at J-PARC is primarily used for academic research in particle and nuclear physics, materials and life science, and so on. In terms of application, it can also contribute to aeras directly benefit our lives, such as the development of nuclear energy, pharmaceuticals, space technology, and semiconductors.
Based on the design of the "Transmutation Experiment Facility" that we have been developing, we are designing a new "Proton Beam Irradiation Facility" that will apply the proton beam to a variety of aeras.
