(3) Long-time measurements of the neutron imaging at a cryogenic temperature by using a Gifford-McMahon (GM) refrigerator. (2) Noise reduction in the readout circuit for increasing the counting rate. Our work plans to fulfill the following items in this project (1) Optimization of the detector design including the thickness of the 10B conversion layer and the details of the detector design for enhancing the detection efficiency. Our intention concentrates on improving the detection efficiency and the spatial resolution of my neutron detector to apply to the non-destructive transmission imaging of various materials such as intermetallic alloys, fuel cells, lithium ion batteries, cultural heritages, and others. We already demonstrated that our detector can reach a resolution as high as 22 μm in our publication. We explain that my detector consists of an orthogonal X and Y meander-lines and superimposed an enriched 10B neutron absorption layer on top. We aims at obtaining a neutron imager with high-spatial resolution, high sensitivity, high temporal resolution, and high-speed measurement system by constructing a new delay-line current-biased kinetic inductance detector (CB-KID) system. Neutron images are known as an important analysis technique in non-destructive imaging in wide areas such as science, medical area, and technology industry to study the properties of a material, co mponent, and system without causing damage. ![]()
