冷阴极磁控管是磁控管发展的重要方向之一。与传统的阴极磁控管不同，这种器件能够瞬时启动，同时具有比传统阴极磁控管更好的稳定性和可靠性。本文报道了四种冷阴极磁控管的冷启动性能，钡-钨（Ba-W）、Ba-W底漆、Pd-Ba合金和金刚石涂覆的阴极。根据测量数据，Pd-Ba（3.5%）合金阴极被认为是最好的磁控管。该磁控管能够立即启动，无需使用额外的灯丝，启动时间不到5秒。同时，它的输出特性，如脉冲宽度和输出功率，与相同结构的磁控管与传统的磁控阴极相媲美。
The cold cathode magnetron is one of the most significant research areas in the development of magnetrons. Unlike the thermionic cathode magnetron, such a device is capable to start up instantaneously, while featuring an excellent stability and reliability as compared with the thermionic one. In this paper, we report on the cold start-up performance of four types of cold cathode magnetrons, i.e., barium-tungsten (Ba-W), Ba-W priming, Pd-Ba alloy, and diamond coated cathodes. Based on the measured data, the Pd-Ba (3.5% in weight) alloy cathode was found to be the best for the magnetron. This magnetron was able to start up instantly without using extra filaments, with a start-up time of less than 5 s. At the same time, its output characteristics, such as pulsewidth and output power, are comparable to the same structural magnetron with conventional thermionic cathodes.
