摘要：
Several designs of magnetrons are discussed in the literature, which are mainly for industrial heating applications. Exotic applications such as current drive systems for plasmas, seeker systems, and accelerator systems may have power and frequency requirements, which are usually not met in the ISM band. This article presents the design of a 3.7-GHz 8-kW continuous wave (CW) magnetron, which can be used as a potential source for the lower hybrid current drive (LHCD) system of a tokamak. The simulation results predict a CW output power of about 8 kW with a 62% efficiency. Furthermore, a novel design of a 16-kW CW stacked magnetron is also presented with a simulated efficiency of 63%.
