The field of research which searches for extremely rare phenomena has developed as it has become difficult to continue building high-energy accelerators. This is the field of non-accelerator physics.
Based on the uncertainty principle which allows high energy to be borrowed for a very short time, it is known that phenomena which occur extremely rarely are a different method to sense phenomena at high energy. Study of non-accelerator physics requires underground laboratory where low radiation background circumstance is realized. Well-known institutes include the Kamioka Observatory in Japan, and Gran Sasso and SNO overseas.
This laboratory conducts research at the Kamioka Observatory.
In order to study elementary particles and atomic nuclei, it is necessary to create the particles which compose them.
Utilizing the fact that mass is equivalent to energy, we can see that higher energy is required in order to create heavier particles. Advancements in accelerator technology have led step by step to advancement in the field of particles and atomic nuclei. In addition to accelerators such as CERN in Europe, which continue to seek higher and higher energy, there is also a type of accelerator which uses lower energy but extremely high intensity beam to search for rare phenomena. J-PARC is an accelerator of this type.
This laboratory also conducts research at J-PARC
