Problems solved by technology

However, the current confinement effect is far worse than that of the tokamak. Also due to its complex magnetic field configuration, the manufacturing is complicated and the cost is high.
[0006] Others such as reverse field, field reverse configuration, and Z-pinch fusion do not yet have the conditions to challenge the tokamak

Abstract

The invention discloses a controllable nuclear fusion device of a dumbbell-shaped structure. A high-temperature plasma constraining apparatus of the device comprises a magnetic mirror apparatus part and annular magnetic constraining apparatus parts. The device is characterized in that the magnetic mirror apparatus part is located at the center of the high-temperature plasma constraining apparatus; the magnetic mirror apparatus part is a magnetic mirror of a hollow cylindrical structure, or consists of multiple cylindrical magnetic mirror bodies which are uniformly arranged at the periphery; the annular magnetic constraining apparatus parts are located at two ends of the high-temperature plasma constraining apparatus; the magnetic mirror apparatus part and the annular magnetic constraining apparatus parts are combined to enable high-temperature plasmas to be communicated with each other to form the dumbbell-shaped structure. The device is effective in magnetic constraining, is simple in structure, and is low in cost.

Description

technical field [0001] The invention relates to the field of controllable nuclear fusion, in particular to a controllable nuclear fusion device with a dumbbell-shaped structure. Background technique [0002] Nuclear fusion is the hope of fundamentally solving human energy problems. Its main advantages are as follows: First, it is rich. According to calculations, every liter of seawater contains 0.03 grams of deuterium, and the deuterium contained in 1 liter of seawater can provide energy equivalent to the energy released after burning 300 liters of gasoline through nuclear fusion. There are 45 trillion tons of deuterium on Earth in seawater alone. It can be said to be inexhaustible energy. The second is clean, because it does not produce radioactive substances that pollute the environment, so it is a clean energy source. The third is safety. The controlled nuclear fusion reaction can be carried out continuously and stably in a thin gas, which is very safe. The two major ...
