Abstract
A neutron grid, comprises: a grid including: a plurality of spacers through which at least a part of first neutrons from a target passes; and a plurality of absorbers to absorb at least a part of second neutrons scattered thorough the target, the spacers and the absorbers being alternately arranged along a first direction and extending along a second direction intersecting with the first direction; and a pair of covers through which at least a part of the first neutrons and at least a part of the second neutrons pass, sandwiching the grid along a third direction intersecting with the first and second directions. A thermal expansion coefficient difference between one of the spacers and one of the absorbers is ±9×10/° C. or less, or Young's modulus of the spacer is 100 GPa or more.
