The invention relates to a leak detection system and method suitable for a linear field antiform nuclear fusion device. Comprising a high vacuum pumping system I, an ultrahigh vacuum pumping system II, a high vacuum pumping system III, an ultrahigh vacuum pumping system IV, an ultrahigh vacuum pumping system V, an ultrahigh vacuum pumping system VII, a gas analysis system I and a gas analysis system II which are connected with a vacuum cavity. The high vacuum pumping system I, the ultrahigh vacuum pumping system II, the high vacuum pumping system III, the ultrahigh vacuum pumping system IV, the ultrahigh vacuum pumping system V and the ultrahigh vacuum pumping system VII are all provided with leak detection systems. According to the invention, vacuum chamber leak detection is carried out by using a shunt leak detection method; meanwhile, a gas analyzer is used for detecting internal gas components when the vacuum cavity is vacuumized, whether helium molecules remain in the vacuum cavity or not is judged, and then a sectional type leak detection method is adopted, so that the problems that detection data are wrong and detection time is too long due to the fact that the vacuum cavity is too large are solved.

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.

Examples of advanced fuel cycles for fusion reactors are described. Examples include fuel cycles for use in field reverse configuration (FRC) plasma reactors. In some examples, reaction gases may be removed from a fusion reactor between pulses (e.g. plasmoid collisions). In some examples, a D-3He reaction is performed, with the 3He provided from decay of byproducts of previous reactions (e.g. tritium).
