中性子源特性試験装置（BL10）始動

抄録

On May 30 2008, the first pulsed-neutron beam from JSNS was successfully observed at NOBORU (BL10). Since then, we have studied neutronic performance of JSNS, such as neutron spectral intensity, pulse shape of cold neutrons and luminosity distribution on the moderator surface. Very good agreements, typically 20 % in absolute values, between the measured and predicted quantities were confirmed with suggesting adequacy of design calculations of JSNS. NOBORU has been also served as a test beam port for users. A variety of leading-edge experiments with featuring high-intensity pulsed neutrons, such as energy-selective imaging, development of neutron devices, prompt gamma-ray analysis, diffraction under high magnetic field, spin-echo experiment, soft error of semi-conductors and calibration field, have been launched.
