| Outline of Final Research Achievements |
Neutron detector CB-KID with a delay-line technique is based on the principle of capturing neutrons by measuring a pair of electromagnetic-wave signals generated by the charged particles emitted from the nuclear reaction of neutrons with boron-10. This causes the superconducting Cooper-pair breaking in the superconducting wire and a sudden change in the kinetic inductance. The four-terminal neutron imaging method was completed in this project. With this detector, the Gd spokes in Siemens star was identified down to 7μm. In addition, YbSn3 single-crystal mosaic structure was imaged from Bragg dip analysis of the YbSn3 single crystals. In addition, the Bragg edge analysis of the Fe sample was successfully performed even with a restricted area of 3.1μm x 2.3μm with CB-KID. A specially-designed cryostat was completed to identify a Gd spoke width down to 14μm located at room temperature. This significantly enhanced the practicality of the CB-KID imaging for various interesting systems.
