The invention belongs to the field of high-performance terahertz radiation sources, and provides an extended interaction klystron and a production method thereof. The extended interaction klystron comprises an input resonant cavity, an output resonant cavity, and N intermediate resonant cavities. The input resonant cavity is communicated with an input waveguide. The output resonant cavity is communicated with an output waveguide. Electron beam channels communicated with one another are arranged at the centers of the input resonant cavity, the output resonant cavity and the N intermediate resonant cavities. The cycle lengths of the resonant clearances of the N intermediate resonant cavities are different or partially different. N is a positive integer greater than 1. The problem that the existing extended interaction klystron has a very narrow working band and high in-cavity power density is solved. An electron beam is tuned by different resonant frequencies when passing through the intermediate resonant cavities. Thus, the working bandwidth of the whole device is improved.
