JAEA/CLADS, had been conducting the Center of World Intelligence Project for Nuclear Science/Technology and Human Resource Development (hereafter referred to "the Project") in FY2018. The Project aims to contribute to solving problems in nuclear energy field represented by the decommissioning of the Fukushima Daiichi Nuclear Power Station, Tokyo Electric Power Company Holdings, Inc. For this purpose, intelligence was collected from all over the world, and basic research and human resource development were promoted by closely integrating/collaborating knowledge and experiences in various fields beyond the barrier of conventional organizations and research fields. The sponsor of the Project was moved from the Ministry of Education, Culture, Sports, Science and Technology to JAEA since the newly adopted proposals in FY2018. On this occasion, JAEA constructed a new research system where JAEA-academia collaboration is reinforced and medium-to-long term research/development and human resource development contributing to the decommissioning are stably and consecutively implemented. Among the adopted proposals in FY2018, this report summarizes the research results of the "Development of Technology for Rapid Analysis of Strontium-90 with Low Isotopic Abundance Using Laser Resonance Ionization". In this study, we will develop a rapid analysis technique for strontium-90 using diode laser-based resonance ionization with elemental and isotopic selectivity. Strontium-90 is one of the major difficult-to-measure nuclides released into the environment due to the accident at Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi Nuclear Power Station. Our method is particularly intended for real samples which contain high concentrations of strontium stable isotopes such as marine samples.

Advanced Light Source (ALS) Beamline 6.0 is designed for X-ray absorption spectroscopy with femtosecond X-ray pulses generated by the bunch "slicing" technique. Soft and hard X-ray branch lines will cover a wide photon energy range from 120 eV to 10 keV. A soft X-ray spectrograph will collect absorption spectra dispersively. The application of laminar gratings to dispersive X-ray absorption spectroscopy in the photon energy range 2- 8 keV has been investigated.

Times Cited Count：76 Percentile：97.53(Instruments & Instrumentation)The present performance of a soft X-ray bealmine BL23SU at SPring-8 is described. The resolving power realized on a varied-line-spacing plane grating monochromator connected to a was estimated to be better than 10000 at 400 eV and 6500 at 867 eV. In addition, reasonable photon flux of more than 10
photons/sec/100mA/0.02% b.w. is available in the energy range of 0.5-1.8 keV at experimental stations.

The nonlinear interaction between terahertz (THz) light and matter has recently been of interest for its availability to control molecular alignment in space. The pulse train of the intense THz light is one of the candidates to align the molecules efficiently and nondestructively. In this study, we have developed the experimental apparatus to generate the intense THz light. The THz etalon to generate the THz pulse train has been presented in our previous study
