Abstract
A sample coil for NMR detection includes a first coil unit and a second coil unit placed with a sample therebetween. In the first coil unit, a first coil and a second coil are formed on a first plane of a first substrate. In the second coil unit, a third coil and a fourth coil are formed on a second plane of a second substrate. Each of the coils is a superconducting coil. When viewed from an x direction orthogonal to the first plane and the second plane, the first coil and the second coil do not intersect the sample, and, similarly, the third coil and the fourth coil do not intersect the sample.
Claims10
An NMR detector comprising:
- a first coil unit that comprises a first superconducting coil, and a first plane on which the first superconducting coil is formed;
- and
- a second coil unit that comprises a second superconducting coil, and a second plane on which the second superconducting coil is formed, and that opposes the first coil unit, wherein
- the first coil unit and the second coil unit radiate electromagnetic waves for generating a high-frequency magnetic field onto a sample placed in a static magnetic field between the first coil unit and the second coil unit, and detect an NMR signal from the sample,
- the first superconducting coil does not intersect the sample when viewed from a direction orthogonal to the first plane, and
- the second superconducting coil does not intersect the sample when viewed from a direction orthogonal to the second plane,
- wherein
- the first superconducting coil comprises:
- a first coil;
- and
- a second coil placed at a position distanced from the first coil, wherein a distance between the first coil and the second coil is greater than or equal to a width of the sample, and
- the second superconducting coil comprises:
- a third coil;
- and
- a fourth coil placed at a position distanced from the third coil, wherein a distance between the third coil and the fourth coil is greater than or equal to the width of the sample.
