Description

TECHNICAL FIELD

[0001] The utility model relates to the field of nuclear fusion technology, specifically, a gas dynamics trap fusion system. BACKGROUND

[0002] As a kind of uncharged particle, neutron has unique penetration ability and the characteristics of being easily absorbed by matter, therefore, it has important application value in many scientific and engineering fields. Neutron source plays a key role in nuclear physics, materials science, biology, medicine and oil exploration and other fields. For example, neutron scattering technology can be used to study the microstructure of materials, neutron irradiation can be used for biological breeding and cancer treatment, and neutron detection can be used to find underground water resources and mineral resources.

[0003] In recent years, with the continuous deepening of nuclear physics and particle physics research, the demand for neutron source is also increasing. Among them, gas dynamics trap fusion device as a potential new type of neutron source fusion device, with simple structure, low cost and easy to control, etc., it has become a research hotspot, and its research helps to expand the field of neutron application.

[0004] The principle of gas dynamics trap fusion device is based on magnetic mirror effect and gas dynamic focusing technology, mainly using the interaction of gas flow and magnetic field. When high-speed plasma flows through the gas flow channel to both sides of gas dynamics trap, it encounters the magnetic mirror formed by magnet, and then returns. But due to the limitation of magnet technology, it is impossible to increase the magnetic field to improve the return rate of plasma. In fact, most of the plasma still cannot be effectively confined in the gas dynamics trap by the magnetic mirror, and will escape from the expansion box at both ends and other areas, resulting in low efficiency of fusion reaction.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] The following describes the gas dynamics trap fusion system 1000 of the embodiment of the present invention with reference to the accompanying drawings. Figures 1 to 3 As shown, the gas dynamic trap fusion system 1000 of an embodiment of the present invention is provided with at least one energy recovery device 100 for the gas dynamic trap fusion system 1000. The energy recovery device 100 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion box 220 of the gas dynamic trap 200. The energy recovery device 100 includes a magnetic field generating component 110 and a power generation component 120.

[0025] The magnetic field generating assembly 110 is arranged on the gas dynamics trap 200, is located between the magnetic mirror 210 of the gas dynamics trap 200 and the expansion box 220 of the gas dynamics trap 200, can generate a deflection magnetic field 111, and can change the movement direction of the plasma a escaping from the gas dynamics trap 200; the power generation assembly 120 is arranged on the gas dynamics trap 200, is located between the magnetic mirror 210 of the gas dynamics trap 200 and the expansion box 220 of the gas dynamics trap 200, is perpendicular to the magnetic field generating assembly 110, and can receive the plasma a after being acted on by the magnetic field generating assembly 110 to form a potential difference that can output an electric current.

[0026] According to the gas dynamics trap fusion system 1000 in the specific embodiment of the utility model, the magnetic field generating assembly 110 changes the movement direction of the plasma a escaping from the gas dynamics trap 200, and then the power generation assembly 120 receives the plasma a, so that the plasma a is used to generate electricity. In other words, the gas dynamics trap fusion system 1000 can recycle the escaping plasma a, avoids the energy waste of the plasma a, and improves the utilization rate of the plasma a in the gas dynamics trap 200.

[0027] As shown in Figures 1 to 3 In order to make the technical scheme of the application easier to be understood, the technical scheme of the application is described in more detail below with the specific embodiment of the gas dynamics trap fusion system 1000.

[0028] In some specific embodiments, as shown in Figure 1 The gas dynamics trap 200 has two magnetic mirrors 210, the plasma a can run back and forth in a limited distance under the action of the two magnetic mirrors 210, but part of the plasma a escapes from the constraint of the magnetic mirror 210, so that the plasma a escapes from the gas dynamics trap 200.

[0029] In some specific embodiments, as shown in Figure 1 The energy recovery device 100 is arranged between the magnetic mirror 210 of the gas dynamics trap 200 and the expansion box 220 of the gas dynamics trap 200. The energy recovery device 100 is provided with at least one, that is, the energy recovery device 100 can be one or multiple, and the number of the energy recovery device 100 in the utility model corresponds to the number of the magnetic mirror 210.

[0030] In some specific embodiments, as shown in Figures 1 to 3As shown, the magnetic field generating assembly 110 is arranged on the gas dynamic trap 200, the power generation assembly 120 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion tank 220 of the gas dynamic trap 200, the power generation assembly 120 is orthogonal to the magnetic field generating assembly 110, and the power generation assembly 120 can receive the plasma a acted by the magnetic field generating assembly 110 to form a potential difference which can output electric current. Specifically, the magnetic field generating assembly 110 mainly generates the deflection magnetic field 111 which can act on the plasma a, that is, when the negatively charged particles and the positively charged particles pass through the deflection magnetic field 111, the negatively charged particles and the positively charged particles will change the motion trajectory under the action of the deflection magnetic field 111. That is, in the process of moving to both ends of the gas dynamic trap 200, most of the plasma a can move back and forth inside the gas dynamic trap 200 under the action of the magnetic mirror 210, but a part of the plasma a still passes through the magnetic mirror 210 and escapes from the constraint of the magnetic mirror 210, thereby escaping from the gas dynamic trap 200. The escaped plasma a can change its motion direction under the action of the magnetic field generating assembly 110.

[0031] In some embodiments, as shown in FIG. 1, the deflection magnetic field 111 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion tank 220 of the gas dynamic trap. Figure 1 As shown, the deflection magnetic field 111 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion tank 220 of the gas dynamic trap. Specifically, the plasma a can move back and forth within a limited distance under the action of the two magnetic mirrors 210, but part of the plasma a escapes from the constraint of the magnetic mirror 210, thereby escaping from the gas dynamic trap 200. The deflection magnetic field 111 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion tank 220 of the gas dynamic trap, and after part of the plasma a passes through the magnetic mirror 210 and escapes from the constraint of the magnetic mirror 210, the magnetic field of the magnetic field generating assembly 110 can act on it to change its motion direction. That is, if the magnetic field of the magnetic field generating assembly 110 is too far away from the magnetic mirror 210, the escaped plasma a can disappear without passing through the deflection magnetic field 111 of the magnetic field generating assembly 110. That is, part of the escaped plasma a is lost and is not utilized. In other words, the deflection magnetic field 111 of the magnetic field generating assembly 110 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion tank 220 of the gas dynamic trap, which can improve the utilization rate of the plasma a.

[0032] In some embodiments, as shown in FIG. 1, the deflection magnetic field 111 is arranged between the magnetic mirror 210 of the gas dynamic trap 200 and the expansion tank 220 of the gas dynamic trap. Figure 1 and Figure 2As shown, the magnetic field generating assembly 110 includes N-level magnetic heads 112 and S-level magnetic heads 113, which are oppositely arranged on the gas-dynamic trap 200 to form the deflection magnetic field 111. Specifically, the N-level magnetic heads 112 and the S-level magnetic heads 113 are oppositely arranged on the gas-dynamic trap 200, i.e., the magnetic field formed between the N-level magnetic heads 112 and the S-level magnetic heads 113 can pass through the gas-dynamic trap 200 and change the moving direction of the plasma a.

[0033] In some embodiments, as shown in Figure 1 and Figure 2 a plurality of N-level magnetic heads 112 are linearly arranged along the length direction of the gas-dynamic trap 200; a plurality of S-level magnetic heads 113 are linearly arranged along the length direction of the gas-dynamic trap 200; and the N-level magnetic heads 112 and the S-level magnetic heads 113 correspond to each other. Specifically, the plasma a escaping from the gas-dynamic trap 200 has different moving speeds, and the plasma a with a larger moving speed changes the moving direction of the plasma a under the action of the magnetic field of the magnetic field generating assembly 110, but the angle of the changed moving direction is small, and the magnetic field range of the magnetic field generating assembly 110 needs to be expanded to further change the moving angle of the plasma a, so that the plasma a can be received by the first electrode plate 121 and the second electrode plate 122, and the probability of the plasma a being received by the first electrode plate 121 and the second electrode plate 122 is improved.

[0034] In some embodiments, as shown in Figure 1 and Figure 2 the N-level magnetic heads 112 and the S-level magnetic heads 113 are connected to form a C-shaped magnet.

[0035] In some embodiments, as shown in Figure 1 and Figure 2As shown, the power generation assembly 120 includes a first electrode plate 121 and a second electrode plate 122, the first electrode plate 121 and the second electrode plate 122 are electrically connected, the first electrode plate 121 and the second electrode plate 122 are oppositely arranged on the gas dynamics trap 200, the first electrode plate 121 and the second electrode plate 122 are parallel to the length direction of the gas dynamics trap 200, the first electrode plate 121 and the second electrode plate 122 are parallel to the magnetic field direction of the power generation assembly 120, and the first electrode plate 121 and the second electrode plate 122 can receive the plasma a after being affected by the magnetic field generation assembly 110 to form a potential difference that can output current. Specifically, when the negatively charged particles and the positively charged particles pass through the deflection magnetic field 111, under the action of the deflection magnetic field 111, the negatively charged particles and the positively charged particles will change the motion trajectory, the first electrode plate 121 receives the positively charged particles, and the second electrode plate 122 receives the negatively charged particles, so that a potential difference is formed between the first electrode plate 121 and the second electrode plate 122 to form an electric current.

[0036] In some embodiments, as shown in Figure 1 and Figure 2 , the first electrode plate 121 is a positive plate, and the positive plate extends along the length direction of the gas dynamics trap 200, wherein in the length direction of the gas dynamics trap 200, the size of the positive plate is greater than the size of the magnetic field. Specifically, a part of the positively charged particles has a large initial speed, and under the action of the deflection magnetic field 111, the curvature of the motion curve of the part of the positively charged particles is large, and when the size of the positive plate is greater than the size of the deflection magnetic field 111, the part of the positively charged particles can still be received by the positive plate, avoiding the loss of the part of the positively charged particles that are not received by the positive plate. In addition, another part of the positively charged particles has a small initial speed, and under the action of the deflection magnetic field 111, the curvature of the motion curve of the part of the positively charged particles is large, and the part of the positively charged particles can be received by the positive plate.

[0037] In some embodiments, as shown in Figure 1 and Figure 2 , the second electrode plate 122 is a negative plate, and the negative plate extends along the length direction of the gas dynamics trap 200, wherein in the length direction of the gas dynamics trap 200, the size of the negative plate is greater than the size of the deflection magnetic field 111. Specifically, the function and principle of the negative plate are similar to those of the positive plate, which will not be described here.

[0038] In some embodiments, as shown in Figure 1 and Figure 2As shown, the positive plate is parallel to the magnetic flux lines of the deflection magnetic field 111. Specifically, the positive plate extends along the length direction of the gas dynamic trap 200, and the positive plate is parallel to the magnetic flux lines of the deflection magnetic field 111, that is, the positive plate and the negative plate are parallel to the length direction of the gas dynamic trap 200, and the positive plate and the negative plate are parallel to the magnetic flux lines of the deflection magnetic field 111. For example, Figure 2 As shown, when the N-stage magnetic head 112 and the S-stage magnetic head 113 are in the up and down directions of the gas dynamic trap 200 , the positive plate and the negative plate are in the left and right directions of the gas dynamic trap 200 .

[0039] It should be noted that when charged particles are affected by the magnetic flux lines in the up and down directions, the charged particles are changed in direction of movement and move left and right, thereby being received by the positive and negative plates.

[0040] In some specific embodiments, Figure 1 and Figure 2 As shown, the negative plate is parallel to the magnetic flux lines of the deflection magnetic field 111. Specifically, the working principle of the negative plate is similar to that of the positive plate, which will not be described in detail here.

[0041] In some specific embodiments, Figure 1 and Figure 2 As shown, a load unit 123 is electrically connected between the first electrode plate 121 and the second electrode plate 122. Specifically, the escaped plasma a is used to generate electricity, and the electrical energy is then stored in the load unit 123.

[0042] In some specific embodiments, Figure 3 As shown, the load unit 123 is electrically connected to the gas dynamic trap 200 to provide electrical energy to the gas dynamic trap 200. Specifically, the electrical energy stored in the load unit 123 is transmitted to the gas dynamic trap 200 to provide electrical energy to the gas dynamic trap 200, thereby improving the utilization efficiency of the gas dynamic trap 200.

[0043] Working principle:

[0044] The plasma a escaping from the gas dynamic trap 200, under the action of the deflection magnetic field 111 of the magnetic field generating component 100, the negatively charged particles will move toward the negative plate and be received by the negative plate. At the same time, the positively charged particles will move toward the positive plate and be received by the positive plate. A potential difference is formed between the positive plate and the negative plate, thereby transmitting electrical energy to the load unit 123, and then the load unit 123 can continuously provide electrical energy to the gas dynamic trap 200.
