Detector technology development for particle and nuclear physics using accelerators

Accelerator Science group carries out research of nuclear and particle physics with high-performance accelerators. In this page, the activities for Research and Development of Detector technology are presented. Particle and Nuclear physics is to study fundamental phenomena once happening at the birth of the Universe by reproducing on earth with accelerators and observing and analyzing with detectors. Therefore, high sensitive experimental devices are essential as well as high performance accelerators and any innovation in those equipment will boost progress in physics.

Electron Scattering

The nuclear force which binds up protons and neutrons in a nucleus originates from the strong interaction between quarks. Though Dr. Yukawa’s meson exchange theory successfully explained important characters of the nuclear force, it is not enough to understand all nature of the nuclear force. Complete understanding of the nuclear force is one of the key issues in nuclear physics.

KamLAND-Zen

Neutrinos are the elementary particles, but they have no electric charges and can be antiparticles themselves. The Research Center for Neutrino Science has conducted an experiment, KamLAND-Zen, to verify the Majorana nature of the neutrinos by finding the “Neutrinoless double beta decay”, which is considered to be the only detectable phenomenon, if neutrinos are the Majorana particles.
