| The goal of the J-PARC proton accelerators is to achieve stable beam operation at 1 MW. Beam loss reduction is crucial to increase beam power and to achieve stable operation. And also, long-lasting components are important for reliable operation. The subject of this theme is to study beam loss reduction for the J-PARC linac and/or 3 GeV Synchrotron (RCS). He/she will perform a study of beam diagnostics, beam loss handling and component development for stabler operation. | ||||||

| The work of neutron instrumentation section focuses on development of various neutron detectors and neutron optical devices for Materials and Life Science Facility (MLF) of J-PARC. Construction of a new neutron diffractometer for analysis of large protein-crystals is now under planning at the MLF. The neutron detectors for the diffractometer are required to have high performances such as large sensitive area and high spatial resolution. The successful applicant will participate in the development of such detectors using scintillators. | ||||||

| Scattering power of protons against neutrons remarkably depends on relative direction of spins of the protons and neutrons. We have developed a dyanamic nuclear polarization system for the proton polarization of composite materials, and then carried out polarized neutron scattering study to determine detailed structure of the materials. We will extend this technique named spin contrast variation to deterimine nano-scale bulk and surface structures using small-angle scattering diffractometers and reflectrometers at the neutron facilities, JRR-3 and J-PARC. | ||||||

| For long-term decommissioning process of the Fukushima Daiichi NPP, it is importatnt to gather and accumulate the data of the working environment as the reference to plan the missons and to use for the workers' training. The objective of this reseach subject is to develp the map building and working enviromental modeling method based on collected sensory data by remote operated robots and sensing systems. Design and implementation of spatio-temporal database to register the working environment data is also included in this research project. | ||||||

| For the decommissioning of TEPCO Fukushima Daiichi Nuclear Power Plants, gamma-ray detectors that can estimate the position, shape and nuclide distributions of residual debris are to be developed. In particular, a prototype detection system consisting of two-dimensional-gamma-imaging units and compact scintillator crystals is developed for the application to fuel debris measurements, and response characteristics of each element to gamma-rays are evaluated. In addition, a compact/lightweight gamma-camera is to be manufactured for the evaluation of its detection capability to radioactive materials and of durability against radiations. An unmanned remote radiation measurement system for the imaging of the radioactivity distribution in the Fukushima reactor building are also to be developed. | ||||||
