Problems solved by technology

[0008] In this way, in the existing neutron detection device, it is not aimed at the high sensitivity and high time resolution of neutron detection, and it is not clear which structure can easily realize the high sensitivity and high time resolution of neutron detection
In addition, although two-dimensional neutron detection is also required, there is a problem that two-dimensional neutron detection cannot be implemented with good sensitivity and time resolution

Embodiment approach

[0080]

[0081] In the above-described embodiments, the material, shape, size, arrangement of the electrode portion 10, and the like of the illustrated superconducting element may also be changed. For example, in the above-mentioned embodiment, the formation containing MgB as the superconducting material 2 stripline 2, but can also be formed on superconducting materials such as Nb, NbN or under superconducting materials 10 The meander-shaped stripline of the compound thin film of the B thin film. In addition, in the above-mentioned embodiment, it was shown that MgB is included as the superconducting material 2 , the above stripline 2 in 10 B is an example of a nuclear reaction with neutrons, but it can also be a combination other than these two combinations.

[0082] In addition, the thickness of each layer constituting the base material 10 positioned below the stripline 2 , the number of layers constituting the base material 10 , and the like may be changed. In addition...

Abstract

A neutron detector having a sensitivity and a time resolution adjustable by simply altering the arrangement of the device. The neutron detector comprises a superconducting element (20) having a substrate (10) where at least one surface is formed of a dielectric material (11), a strip line (2) made of a superconducting material and formed on the surface, and electrodes (1) formed at both ends of the strip line (2), and a plurality of neutron detecting element sections having a resistance measuring means for measuring heat generation through nuclear reaction of a superconducting element and a neutron in the strip line (2) based on variation in resistance of the strip line (2), and a heat dissipation adjusting means (5) provided on the back of the substrate opposite to the surface where the strip line (2) is formed and adapted for adjusting dissipation properties of heat generation through nuclear reaction. The heat dissipation properties are differentiated among the neutron detecting element sections.

Description

technical field [0001] The present invention relates to a neutron detector (neutron detector) and a neutron imaging sensor (neutron imaging sensor) including a plurality of neutron detection element parts. Background technique [0002] Conventionally, development of a device using a material with a high superconducting transition temperature has been carried out. As a superconducting material with a high superconducting transition temperature, MgB with a superconducting transition temperature of 39K is known. 2 . And, for example, to include 10 B as a structural material with a large energy gap 10 B was enriched with MgB 2 As a neutron detection plate, phonons generated by α-rays generated when neutrons enter are detected on the detection plate (for example, refer to Patent Document 1). [0003] In addition, neutron imaging sensors that can detect neutrons in two dimensions using scintillator plates have also been proposed. Such a neutron imaging sensor includes a scin...
