description The invention discloses a method for realizing cylindrical grating coherent Smith-Purcell radiation enhancement, Smith-Purcell radiation is incoherent spontaneous radiation, the power of the radiation is very low, and the radiation is not easy to detect and apply, and in order to realize high-intensity Smith-Purcell radiation, the invention provides an enhancement method based on a quasi-continuous domain bound state. Firstly, an electron gun is used for generating an electron group string; then, the electron group string passes through the surface of the cylindrical metal grating, the repetition frequency of the electron group string is used as the resonant frequency of the bound state of the quasi-continuous domain, the enhancement of coherent Smith-Purcell superradiation is realized, and the electrons finally enter a collector. The cylindrical grating coherent Smith-Purcell radiation enhancement method provided by the invention has the characteristics of simple operation, obvious effect, easy integration,
