Abstract: Due to the advantages of clean and environmentally friendly,abundant raw material reserves,safety and reliability,and no nuclear waste,sustainable green energy nuclear fusion has become an important choice to solve energy and environmental problems in future.However,achieving controlled nuclear fusion is not easy.Tokamak is the most promising magnetic confinement device to realize controllable fusion energy.High power vacuum launch tube is an important component in the Tokamak device.As an important index of the limit parameter and rated power of the transmitting tube,its current depends on the structure,size,material of the transmitting tube itself.The structure and working principle of the tetrode are very complex,so it is very difficult to obtain the variation of emission current with its structural parameters.Therefore,the tetrode can be equivalent to diode structure to explore the law of space charge limited current of diode changing with its geometric structure.The results can provide reference and theoretical basis for the structure design and optimization of the plasma heating transmitting tube.At present,there are many analyzing methods and special simulation software,and they have been widely used in the space charge limiting current.In this regard,by reviewing the related literature and books,the research status of the space charge limited current of the diode at domestic and overseas are summarized and analyzed,and the development tendency is prospected.

Key words: nuclear fusion, transmitting tube, vacuum diode, space charge limited current, thermionic emission
