パルス強磁場下における中性子回折技術の開発と応用

抄録

We have established the fundamental technology for neutron diffraction experiments under high magnetic fields by combining pulsed magnets and spallation neutron sources at Materials and Life Science Experimental Facility (MLF) in Japan Proton Accelerator Research Complex (J-PARC). This system includes a vacuum chamber, a 4 K closed-cycle refrigerator for samples, and a small pulsed coil immersed in a liquid nitrogen bath made of a stainless-steel tube. The compactness and portability facilitate easy installation at any existing beamlines for practical user applications. In this article, the history of the developments of our pulsed high magnetic field neutron diffraction is described, with a particular focus on our achievement realized at Beamline No. 10 (NOBORU) in MLF.
