The present invention relates to a generation chamber for a neutron imaging system, which can generate an image from neutrons of each energy band emitted from a neutron source emitting neutrons of energies of 2 or more different bands. The neutron source may emit 2 or more of thermal neutrons (thermal neutrons) having an energy ranging from 0.005eV to 0.5eV, epithermal neutrons having an energy ranging from 1eV to 10eV, and fast neutrons having an energy of 0.5MeV or more.
Fig. 1 is a perspective view showing the structure of an image generation chamber for a neutron imaging system according to an embodiment of the present invention.
Referring to fig. 1, an image generation chamber for a neutron imaging system according to an embodiment of the present invention includes: a shielding member 110, a mirror 120, and a scintillator replacement member 130.
The shielding member 110 shields a neutron beam other than the visible light generated by conversion of a neutron beam in a partial range of an emission range of the neutron beam emitted from the neutron source, and receives only the visible light. The shielding member 110 includes a shielding space 110a and a socket portion 110b into which visible light is incident to the shielding space 110a. As an example, the shielding member 110 may be configured in a box shape, and the inside of the box may be a shielding space 110a. The socket portion 110b opens one side of the shielding space 110a to make the visible light incident, and is used to connect the scintillator replacement member 130 to the shielding member 110. As an example, the socket 110b may have a square ring shape. An image sensor 300 for generating an image may be provided on one side of the shielding member 110, that is, on a side surface perpendicular to the surface on which the socket 110b is provided.
The reflecting mirror 120 accommodates the shielding space 110a, and converts a traveling direction of the visible light incident to the shielding space 110a to be directed toward the image sensor 300.
The scintillator replacing member 130 is formed of a combination of a plurality of scintillators different from each other in response to neutron energy reaction of each frequency band emitted from the neutron source. The scintillator replacement member 130 includes an adapter portion 131 and at least 2 scintillator portions 132
The adapter portion 131 is connected to the socket portion 110b for connecting the scintillator replacing member 130 to the shielding member 110. As an example, the adapter portion 131 may have a square ring shape, and may have a size capable of accommodating the socket portion 110b. The form in which the adaptor part 131 is connected to the socket part 110b is not particularly limited, and for example, one of a groove and a protrusion is formed around each of the adaptor part 131 and the socket part 110b, and may be one-touch and separate.
The scintillator portion 132 may be at least 2 such that there are at least 2 scintillators 1321 that respectively convert neutrons of at least 2 energy bands emitted from the neutron source into visible light. The at least 2 scintillators 1321 are the same distinct scintillator that converts each neutron to the visible light as opposed to a neutron source that emits neutrons of energy in more than 2 distinct bands.
As an example, the scintillator portion 132 may include: 3 scintillator mounting members 1322 in the shape of a square ring, which are rotatably connected to 3 sides of the square ring of the adapter portion 131, and 3 scintillators 1321, which are accommodated inside the square ring of each scintillator mounting member 1322. In this case, one of the 3 scintillators 1321 may be of a type that converts thermal neutrons into visible light, the other may be of a type that converts epithermal neutrons into visible light, and the remaining one is of a type that converts fast neutrons into visible light.
In the scintillator replacing member 130, when each scintillator portion 132 is closed toward the adapter portion 131, the scintillator 1321 provided in each scintillator portion 132 faces the shielding space 110a. Accordingly, each of the scintillator sections 132 is rotated toward the adapter section 131 according to neutron energy emitted from the neutron source 200, and the scintillator 1321 provided at each of the scintillator sections 132 is opposed to neutrons, so that the scintillator 1321 can be replaced according to neutron energy in such a manner that each of the scintillators 1321 converts each of the neutrons into visible light.
The image generation chamber for a neutron imaging system according to an embodiment of the present invention can couple and decouple the scintillator-replacing member 130 and the shielding member 110 by coupling and uncoupling the adapter portion 131 of the scintillator-replacing member 130 with and from the socket portion 110b of the shielding member 110. Therefore, the portable bag is convenient to carry.
In one aspect, in the image generation chamber for a neutron imaging system according to an embodiment of the present invention, the shielding member 110 may be configured to be folded for more convenient carrying.
That is, the shielding member 110 may be configured such that the sides of the square box are rotatably connected to each other, and the sides are rotatably folded to overlap each other. For this, the shielding member 110 includes: a planar plate 111, a bottom plate 112, a first side plate 113, a second side plate 114, a front plate 115, and a back plate 116 rotatably connected to each other.
The flat plate 111 forms a flat surface of the shielding member 110, and the bottom plate 112 forms a bottom surface of the shielding member 110 opposite to the flat plate 111.
The first side plate 113 forms one side surface of the shielding member 110, is rotatably connected between the flat plate 111 and the bottom plate 112, and includes a first folded portion 113a extending in a lateral direction. The first folding portion 113a is a boundary for folding the first side panel 113, and is a portion where the first side panel 113 is divided into 2 first small unit panels 113b, and one side edge of each of the first small unit panels 113b is hinge-connected to each other. Accordingly, the first side panels 113 are overlapped with each other by the rotation of each of the first small unit panels 113b, and can be folded with the first folding portion 113a in mind.
The second side panel 114 forms the other side surface of the shielding member 110, is rotatably connected between the flat panel 111 and the bottom panel 112, and has a second folded portion 114a extending in the lateral direction. The second folding portion 114a is a boundary for folding the second side panel 114, and is a portion where the second side panel 114 is divided into 2 second small unit panels 114b, and one side edge of each second small unit panel 114b is hinged to each other. Therefore, the second side panels 114 are overlapped with each other by rotating the second small unit panels 114b, and can be folded with the second folded portion 114a in mind.
The front plate 115 forms a front surface of the shielding member 110, and is rotatably connected to one of the flat plate 111 and the bottom plate 112 so as to be perpendicular to the first side plate 113 and the second side plate 114. As an example, the front plate 115 is rotatably connected to the flat plate 111. At this time, the front panel 115 may be positioned inside the first side panel 113 and the second side panel 114. The socket 110b may be provided at a lower portion of the front panel 115.
The back plate 116 forms a back surface of the shielding member 110, and is rotatably connected to the remaining one of the flat plate 111 and the bottom plate 112 so as to face the front plate 115. As an example, the back plate 116 is rotatably connected to the bottom plate 111. At this time, the back plate 116 may be positioned inside the first side plate 113 and the second side plate 114.
In addition, at least one of the front plate 115 and the back plate 116 may include a support portion 117. As an example, the front plate 115 and the back plate 116 may each include the support portion 117. In this case, each supporting portion 117 may be formed to protrude to both sides of the front and rear plates 115 and 116 in the longitudinal direction. Each supporting portion 117 is faced to the inner side surfaces of the first side panel 113 and the second side panel 114, and can support the first side panel 113 and the second side panel 114 in a unfolded state.
Next, a process in which the shutter member 110 of the folding structure is folded and a process in which it is unfolded in a box shape will be described.
In order to fold and unfold the shielding member 110 in a box shape, when the front panel 115 is rotated in the direction of the flat panel 111 and the rear panel 116 is rotated in the direction of the bottom panel 112, the front panel 115 and the rear panel 116 are spaced apart from the first side panel 113 and the second side panel 114. At this time, each support 117, which is in surface contact with the inner surfaces of the first side plate 113 and the second side plate 114, among the front plate 115 and the rear plate 116 is spaced apart from the first side plate 113 and the second side plate 114.
When the front and rear panels 115 and 116 are rotated to be spaced apart from the first and second side panels 113 and 114, the supporting portions which hold and support the first and second side panels 113 and 114 in the erected state and the position of the plane plate 111 are spaced apart, so that the first side panel 113 is rotated to overlap each of the first small unit panels 113b and folded about the first folding portion 113a, and the second side panel 114 is rotated to overlap each of the second small unit panels 114b and folded about the second folding portion 114a. At this time, the first side panel 113 and the second side panel 114 are folded and rotated in the inner direction of the flat panel 111 and the bottom panel 112.
Thus, when the first side panel 113 and the second side panel 114 are folded, the first side panel 113 and the second side panel 114 are folded onto the bottom panel 112, and the flat panel 111 is folded onto the first side panel 113 and the second side panel 114 in the folded state. In this state, when the front panel 115 is folded onto the upper surface of the flat plate 111 and the back panel 116 is folded onto the opposite surface of the bottom panel 112, that is, the opposite surface of the folded surfaces of the first side panel 113 and the second side panel 114, the shielding member 110 is folded into a flat state as shown in fig. 5. Thereby, the shielding member 110 is more easily carried.
When the shielding member 110 is to be unfolded for use, the back plate 116 is first separated from the bottom plate 112, the back plate 116 and the bottom plate 112 are placed on the ground, and then the front plate 115 and the flat plate 111 are lifted up while the front plate 115 is folded, the first side plate 113 is unfolded while rotating about the first folded portion 113a, and the second side plate 114 is unfolded while rotating about the second folded portion 114a.
In this state, the front panel 115 and the back panel 116 are rotated toward the first side panel 113 and the second side panel 114. As an example, the back plate 116 is rotated toward the first side plate 113 and the second side plate 114 so that the supporting portions 117 on both sides of the back plate 116 are inserted into the inner sides of the first side plate 113 and the second side plate 114, and then the front plate 115 is rotated toward the first side plate 113 and the second side plate 114 so that the supporting portions 117 on both sides of the front plate 115 are inserted into the inner sides of the first side plate 113 and the second side plate 114. In this way, the support portions 117 of the front panel 115 and the rear panel 116 are in contact with the inner surfaces of the first side panel 113 and the second side panel 114, so as to support the first side panel 113 and the second side panel 114 in the unfolded state, and support the position of the flat panel 111. Thereby, the shielding member 110 is held in a state of being unfolded into a box shape.
In this way, in a state where the shielding member 110 is unfolded into a box shape, the adapter portion 131 of the scintillator replacement member 130 is coupled to the socket portion 110b of the shielding member 110 to convert neutrons into visible light generation images.
Using the image generation chamber for a neutron imaging system according to an embodiment of the present invention has the following advantages. The portable neutron imaging system is convenient to carry, so that the portable neutron imaging system can be carried to various places where the neutron source is located to construct an imaging system, the portable neutron imaging system can be realized by replacing a large-scale and high-price neutron imaging system, and an image can be generated corresponding to broadband energy neutrons.
In addition, an image generation chamber for a neutron imaging system according to an embodiment of the present invention may be utilized for a neutron imaging system, and a neutron imaging system using such an image generation chamber, as shown in fig. 6, may include a neutron source 200, an image generation chamber 100, and an image sensor 300. Fig. 6 is a conceptual block diagram illustrating the structure and arrangement of a neutron imaging system according to an embodiment of the invention.
As described above, the neutron source 200 may emit more than 2 of thermal neutrons, epithermal neutrons and fast neutrons.
The image generation chamber 100 is disposed opposite neutrons emitted from the neutron source 200, and can convert neutrons into visible light to generate an image.
As described above, the image sensor 300 is disposed at one side of the image generation chamber 100, and can receive a visible light generated image. As an example, the image sensor 300 may be a CCD sensor, and may be connected to a display device that outputs an image.
In order to generate an image of the subject 10 through which neutrons pass by the neutron imaging system according to an embodiment of the present invention, the neutron source 200 emits neutrons to the subject 10, the image generation chamber 100 converts neutrons passing through the subject 10 into visible light and travels the converted visible light to the image sensor 300, which receives the visible light and generates an image.
In this process, the scintillator replacing member 130 of the image generating chamber 100 rotates each scintillator section 132 toward the adapter section 131 according to neutron energy emitted from the neutron source 200 so that the scintillator 1321 provided in each scintillator section 132 is opposed to neutrons, whereby each scintillator 1321 can convert each neutron into visible light.
The neutron imaging system according to an embodiment of the present invention has an advantage that it can provide a neutron imaging system in that, due to the structure in which scintillators are replaceable and configured according to the neutron energy, scintillators suitable for the neutron energy can be quickly and simply replaced in one standard neutron imaging system, thereby providing a neutron imaging system corresponding to neutrons of broadband energy
Further, since the object image can be generated by promptly replacing and disposing the scintillator suitable for the neutron energy level, there is an advantage that a high-resolution object image can be obtained from neutrons of energy in each band.
The description of the embodiments is provided to enable any person skilled in the art to which the invention pertains to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention.
