Abstract
Magnetron production and use far exceed that of other microwave tubes due to their high operational efficiency, power efficiency, and cost-effectiveness in production. The magnetron was named by A. W. Hull; however, the device invented by Hull differs from the magnetron utilized as a microwave tube. The magnetron widely used today is based on the split-anode magnetron invented by K. Okabe. This overview introduces two papers published by Okabe in the Proceedings of the Imperial Academy and discusses the events that led to the discovery of the split-anode magnetron. In addition, the operation mechanisms of magnetrons are explained.
磁控管的生产和使用远远超过了其他微波管，因为它们具有很高的运行效率、功率效率和生产成本效益。磁控管由 A. W. Hull 命名，但 Hull 发明的装置与用作微波管的磁控管不同。目前广泛使用的磁控管是基于 K. Okabe 发明的分阳极磁控管。本概述介绍了 Okabe 在《帝国科学院院刊》上发表的两篇论文，并讨论了导致发现分裂阳极磁控管的事件。此外，还解释了磁控管的运行机制。
