Today, the compression of the klystron tube is one of the most important topics for accelerators, along with high output power and efficiency. Multi-beam klystrons have the ability to generate high output power, with lower working voltage and interaction length of the wavelength with the beam than single-beam klystrons, and as a result, they will have less volume and weight. In this paper, the design and simulation of the wave-beam interaction region for a 40-beam klystron tube in S-band has been done using the second harmonic method, and the increase in efficiency has been introduced for the first time by the design method with a clustered cavity. According to the results of design, simulation and then optimization by local method, the output power of 15MW has been achieved in the interaction length of 238.8mm for the working frequency of 2856MHz and the input power of 13W. The efficiency and gain of the structure are equal to 76% and 60.66 dB, respectively.
