PETIS has been applied for analyses of cadmium transport from the root organ to the grains in rice plants in previous studies. In this study, we first realized direct imaging and quantitative analysis of the dynamic process of cadmium transport from hydroponic culture to shoot via root organ. When a radiotracer is applied to plant roots for imaging experiments, it has been usual that the region of application is shielded or set off from the field of view because of too high radioactivity there. We successfully obtained serial quantitative images by developing suitable vessels for observation and arranging best radioactivity of the tracer. High-Cd-accumulating lines of rice and Sedum, a hyper accumulator plant for heavy metals, were subjected to this experimental system and analyzed for their abilities of Cd uptake.

2D neutron diffraction imaging of an ammonite fossil was carried out at high-intensity total diffractometer NOVA in J-PARC. Observed diffraction profiles consist of calcite, siderite and amorphous structures. Most of part in the ammonite is calcite. The calcite image shows air chambers divided by septa in the spiral shell. Siderite is observed only in the body chamber. Amorphous structure is observed in both the protoconch and the inner whorls.

Neutron diffraction imaging for a SUS430 plate embedded in a copper block sample has been tested at the high-intensity total diffractometer NOVA in J-PARC, the High-Resolution Powder Diffractometer HRPD and the diffractometer for Residual Stress Analysis RESA in JRR-3. The results are also compared with that measured at the Thermal Neutron Radiography Facility TNRF in JRR-3.
