Description

  The present invention relates to a neutron generation apparatus and generation method by nuclear fusion using electromagnetic interaction.

  Conventionally, neutron generation methods include a method using a nuclear fission reaction such as uranium and plutonium, and a method of generating a target by irradiating charged particles such as accelerated protons.

These have the following disadvantages.
In order to generate neutrons, a huge nuclear reactor and accelerator are required, so the places where they can be installed are limited, and they are expensive to use. In the case of nuclear reactors, the storage and disposal of nuclides is enormous, and once an accident occurs, there is a risk of serious damage to the facility and surroundings.
The present invention has been made to eliminate the above drawbacks.

A container having an inner space radially arranged toward the outer side of the rotating shaft so as to be rotatable around the rotating shaft and having a metal disposed on the outer portion of the inner space is installed. A magnetic field generator that generates a magnetic field in a certain direction along the rotation axis of the container is disposed on the rotation axis. In addition, an electromagnetic wave generator that applies electromagnetic waves to the inner sky will be installed.
The present invention is a neutron generator by nuclear fusion having the above configuration.

A solution containing tritium ions and deuterium ions or a gas containing tritium ions and deuterium ions is put into the inner space of the container. A magnetic field in a certain direction is generated so as to cover the entire inner space along the rotation axis direction of the container. Next, the container is rotated in a certain direction around the rotation axis. By this rotation, Lorentz force from the magnetic field acts on the ions in the inner space, and moves to the inside or outside of the rotation axis according to the charge of the ions. By setting the direction of the magnetic field so that positive ions move outward, the tritium ions and deuterium ions move to the outer part of the inner space and approach each other. Since the metal in the outer portion of the inner space moves in the magnetic field, Joule heat is generated due to the eddy current, thereby heating the solution or gas. Furthermore, it heats by applying electromagnetic waves from outside the container to the solution or gas in the interior. As a result, the movement speeds of the tritium ions and deuterium ions increase, and by maintaining this state for a long time, nuclear fusion occurs between the tritium ions and the deuterium ions by the tunnel effect, and neutrons are generated. The present invention
Neutrons can be generated with a relatively simple device, so installation is easy and there is less radioactive waste than nuclear reactors. Tritium ions and deuterium ions are readily available and can be used at a relatively low cost.

Hereinafter, modes for carrying out the present invention will be described.
As shown in FIG. 1 and FIG. 2, the rotating device (11) is used to rotate around the rotation axis, and has an inner space (2) radially arranged toward the outside of the rotation axis. A container (1) in which a metal (3) is arranged on the outer part of the inner space is installed. A magnetic field generator (10) that generates a magnetic field in a certain direction along the rotation axis of the container is disposed on the rotation axis. Furthermore, an electromagnetic wave generator (4) that applies an electromagnetic wave (5) to the inner space is installed.
The present invention has the above structure.

  When using the present invention, a solution containing deuterium ions or a solution containing tritium ions and deuterium ions is put into the inner space (2) of the container from the inlet / outlet (12). Alternatively, a gas containing deuterium ions or a gas containing tritium ions and deuterium ions is put into the inner space of the container. A magnetic field in a fixed direction is generated by the magnetic field generator (10) so as to cover the entire inner space along the rotation axis direction of the container. Next, the container is rotated in a fixed direction around the rotation axis by the rotating device (11). By this rotation, Lorentz force from the magnetic field acts on the ions in the inner space, and moves to the inside or outside of the rotation axis according to the charge of the ions. By setting the direction of the magnetic field so that the positive ions move outward, the deuterium ions (7) and the tritium ions (6) move to the outer part of the inner space. Since the metal (3) in the outer portion of the inner space is moving in the magnetic field, Joule heat is generated due to the eddy current and heats the ions in the inner space. Furthermore, it heats by applying electromagnetic waves (5), such as a microwave, from the outside of the container to the solution or gas in the interior. This increases the speed of movement of the close deuterium and tritium ions. By maintaining this state for a long time, nuclear fusion occurs between deuterium ions or between tritium ions and deuterium ions by the tunnel effect, and neutron (9) is generated.

A strong acid is used as a solution or gas containing deuterium ions or tritium ions and deuterium ions used in the present invention. Strong acids have a strong ionization of cations and anions,
The concentration of tritium ions and deuterium ions can be easily increased. In addition, the concentration and amount of tritium ions and deuterium ions can be easily determined.

  In order to suppress the chemical reaction between the metal installed in the outer portion of the inner space of the present invention and the solution or gas in the inner space, the metal is arranged so as not to contact the inner space as shown in FIG.

  As shown in FIG. 4, the magnetic field generator is installed outside the container. This also generates a magnetic field along the rotation axis.

  In order to increase the Lorentz force acting on the ions in the inner space of the present invention, the magnetic field generator is rotated around the rotation axis of the container in the direction opposite to the container.

Example 1: Application to boron neutron capture therapy Boron neutron capture therapy is known as an antitumor therapy using neutrons. When a boron compound with a mass number of 10 was administered to a patient in advance and neutrons were irradiated when boron was collected in the tumor, a nuclear reaction between boron inside the cell and thermal neutrons occurred in tumor cells that had taken in a lot of boron. Alpha rays and mass 7 lithium particles damage tumor cells. This treatment method requires a large facility for neutron irradiation, so the feasible facilities are very limited. Therefore, it is possible to easily receive boron neutron capture therapy by covering the periphery of the present invention with a shielding material such as concrete so that neutrons can be extracted in a narrow range.

Example 2: Use of neutron energy In order to use the generated neutron energy as heat energy or electric energy, a water tank is installed around the main body and water is circulated. The water heated by absorbing the neutrons generated according to the present invention is used as a thermal energy source, or the turbine connected to the generator using the heated water is rotated and used as an electrical energy source.

Example 3: Generation of tritium Tritium is generated by placing lithium or a compound containing lithium around the neutron generator and reacting the neutron generated according to the present invention with lithium. This tritium is recovered and used.
