JENDL-5 released in 2021 includes enough cross section data for neutron activation calculations. Thus we have produced ORIGEN and ORIGEN-S libraries from JENDL 5. We also produced the similar libraries from JENDL/AD-2017 for comparison. Analyses of the JPDR decommissioning data with these libraries demonstrated that the libraries had no problem.

A SCALE6.2 ORIGEN library was produced with the AMPX-6 code from JENDL Activation Cross Section File for Nuclear Decommissioning 2017 (JENDL/AD-2017). For validation of the libraries, JPDR activation calculation was performed with ORIGEN and the libraries, which demonstrated the library had no problem.

Times Cited Count:12 Percentile:46.98(Physics, Applied)We previously reported that the magnetic state of FeRh can be controlled by irradiation with ion beams. In this paper, we evaluate possibility of magnetic patterning on FeRh thin films using energetic light ion microbeam irradiation with various shapes and dimensions. Proton microbeam irradiation with 2 MeV was performed at JAEA-Takasaki to produce micron-sized magnetic patterns. XMCD-PEEM observation was performed at SPring8 to confirm the synthesized magnetic patterns. As a result, the XMCD-PEEM images of the various micrometer sized patters in FeRh film were observed using 2 MeV H ion beam. The observed bright regions are considered to have ferromagnetic spin orders, in contrast that the gray areas have anti-ferromagnetic spin order. Since the brightness of the PEEM images is strongly correlated with the magnetization of the samples, we reveal that the magnetic state in local regions of the FeRh thin films can be controlled by changing the ion fluences.

Times Cited Count:18 Percentile:62.15(Instruments & Instrumentation)X-ray line spectra ranging from 17 to 77 keV were quantitatively measured with a Laue spectrometer, composed of a cylindrically curved crystal and a detector. Either a visible CCD detector coupled with a CsI phosphor screen or an imaging plate can be chosen, depending on the signal intensities and exposure times. The absolute sensitivity of the spectrometer system was calibrated using pre-characterized laser-produced X-ray sources and radioisotopes. The integrated reflectivity for the crystal is in good agreement with predictions by an open code for X-ray diffraction. The energy transfer efficiency from incident laser beams to hot electrons, as the energy transfer agency for specific X-ray line emissions, is derived as a consequence of this work.

Times Cited Count:10 Percentile:37.91(Physics, Applied)We demonstrate the potential of a hydrothermal method-grown ZnO as a high-spatial resolution imaging device for in-situ soft X-ray laser diagnostics by characterizing the exciton emission patterns. By plotting the emission pattern radii at each position, we estimated the evolution of the beam radius around the focal point. The beam profile of the Ni-like Ag ion plasma laser was estimated from the waist radii as 29 and 21m, the divergence angle as 7.2 and 11 mrad and the M2 factor as 47 and 50 in the horizontal- and vertical-axis, respectively. Spatial resolution of the magnifier was estimated to be 6m and is expected to improve by optimizing the optics of the magnifier and using a telescope. Our results would enhance the use of ZnO as an imaging device that would play a crucial role in the development and application of soft X-ray light sources.

Times Cited Count:104 Percentile:92.65(Biochemistry & Molecular Biology)Legume plants tightly control the development and number of symbiotic root nodules. In , this regulation required in the shoots, suggesting that a long-distance communication between the shoots and the roots may exist. To better understand its molecular basis, we isolated and characterized a novel hypernodulating mutant of named (). Reciprocal grafting with wild type showed that hypernodulation is determined by the root genotype. Moreover, grafting a shoot onto a rootstock did not exhibit any obvious additive effects on the nodule number. These observations indicate that a shoot factor and a root factor participate in the same genetic pathway which governs the long-distance signaling of nodule number control. may function downstream of and the gene product might serve as a receptor or mediator of unknown mobile signal molecules that are transported from the shoots to the roots.

Some disaster wastes polluted with the radioactive cesium diffused in the accident of the Fukushima Daiichi Nuclear Power Plant are incinerated in the refuse incineration plant. It is thought that cesium is not emitted outside since cesium is coagulated to the refuse incineration ash and trapped by a bag filter or an electric dust collector. Therefore, we report the simulation of the behavior of cesium in an incineration plant.
