Radiation Physics and Measurement



Measurement of neutrons

Fermi National Accelerator Laboratory, USA

Radiations (energetic neutron, prton, photon, electron, etc.) are widely utilized for nuclear engineering, material science, biology, medical science, environmental science, archaeolgy and so on. Our research goal is sophistcated radiation utilization in various fields. We study nuclear reactions such as neutron production from MeV to GeV region for radiation therapy and accelerator driven subcritical system. Weak interaction has been passed up in usual day because of it's difficulty of detection. Solution of weak interaction mechanism is investigated for daily use of neutrinos. Various types of radiation detectors using experimental techniques in low temperature physics have been developed for innovative X-ray spectroscopy required in wide range of fields such as nuclear fuel facilities, synchrotorn radiation facilities, electron microscope facilities and space science satelites. Generation of pulse intense neutron field using a proton accelerator is studied for noninvasive brain tumor treatment. (130 words)
