Times Cited Count:28 Percentile:79.02(Multidisciplinary Sciences)After the discovery of X-ray by Rontgen, mankind got a new eye to see through things. This fluoroscopy, so-called X-ray radiography that gives the density distribution of the inside of an object, has been applied to the vast research field such as natural/material/medical sciences, industry and technology. The recent development on the intense pulsed muon source at J-PARC MUSE (rate of 106 cps for 60 MeV/c) enabled us to pioneer a new frontier of analytical sciences. Here we report on a non-destructive elemental analysis by using muon capture. Controlling muon's momentum from 32.5 to 57.5 MeV/c. we successfully demonstrated a depth-profile analysis of light elements from several mm-thick layered materials, and non-destructive bulk analyses of meteorites containing organics. Now it is a beginning to utilize a new eye, muon radiography.

Times Cited Count:11 Percentile:56.62(Instruments & Instrumentation)A Si(111) winged crystal has been designed to minimize anticlastic bending and improve sagittal focusing efficiency. The crystal was thin with wide stiffening wings. The length-to-width ratio of the crystal was optimized by finite element analysis, and the optimal value was larger than the "golden value". The analysis showed that the slope error owing to anticlastic bending is less than the Darwin width. The X-rays were focused two-dimensionally using the crystal and a tangentially bent mirror. The observed profiles of the focal spot agreed well with the results of a ray-tracing calculation in the energy range from 8 to 17.5 keV. X-ray diffraction measurements with a high signal-to-noise ratio using this focusing system were demonstrated for a small protein crystal.

For accurate prediction of neutronic characteristics for accelerator-driven system (ADS), an experimental program to measure nuclear data on ADS using the Fixed Field Alternating Gradient (FFAG) accelerator at Kyoto University has been launched. As a part of this program, energy spectra of spallation neutron from 100-MeV proton-induced reactions on Fe, Pb, and Bi are plan to be measured. In this report, the results of the measurement on Fe target will be presented.

Toward the realization of Accelerator-Driven System (ADS), we have been measuring the nuclear data for ADS using Kyoto University FFAG accelerator. In this presentation, we report the outline and the results of the energy spectrum measurement of neutrons produced by 107 MeV proton-induced reactions on lead and bismuth, which are the most important nuclides in ADS.
