This invention relates to the field of controlled
nuclear fusion technology, providing a magnetic inertial fusion device and method for accelerating and compressing field-inverted
plasma. The device is an integrated linear structure, comprising, from both ends to the middle, a
divertor chamber, a field-inverted
plasma formation section, a
linear acceleration section, a
conical tube pre-compression section, and a collision-fusion and magnetic compression region. FRC
plasma is formed in the formation section, its axial velocity is increased in the acceleration section, and then pre-compression and stability are improved in the
conical tube pre-compression section. After the plasmas at both ends collide and fuse in the middle region, they are magnetically compressed by electromagnetic pulses to reach a
medium density (~10²⁴ m⁻³) and fusion temperature, triggering the fusion reaction. The above process can be repeated, the stability of the fusion plasma can be effectively controlled throughout the process, the pulse power heating of the plasma is highly efficient, and the plasma temperature and density can be controlled to simultaneously reach the required fusion conditions; providing an optimal solution for the commercialization of fusion energy.
