本文阐述用等效电路的概念确定200.6兆赫、40千瓦高频腔的主要尺寸的方法,讨论了调谐装置的设计。在1500兆赫模拟装置上测出电感调谐曲线,并探索了在满束流负载下高频腔可能的最佳耦合环尺寸。实践表明,用等效电路法辅以模拟测试仍然是设计高频腔的一种较为简便而有效的方法。
This article describes a method of determining the major dimensions of a 200.6 MHz, 40 kW HF cavity using the equivalent circuit concept and discusses the design of the tuning device. The inductance tuning curve was measured on a 1500 MHz analog device and the best possible coupling ring size for the RF cavity at full beam load was explored. Practice shows that the equivalent circuit method supplemented by analog test is still a high-frequency cavity design is a more convenient and effective method.
