【摘要】 扇调管是在偏调管基础上发展起来的一种高效率微波管。它的导流系数比偏调管的高,有可能工作于较低的束电压。相应地,它的输出腔则采用有双脊截面的环形腔。本文采用近似方法对这种环形腔进行了分析,详细介绍了它的设计及优化方法。最后,给出了模型腔的测试结果。它与理论计算基本吻合。更多还原

【Abstract】 Secmotron (Sector beam deflection modulated tube) is a new kind of high efficient microwave tube which is developed on the basis of gyrocon. Its pervance is higher than that in gyrocon. Therefore, the,secmotron can be operated at rather lower voltage. Consequently, a double ridge ring cavity is used as its output one. The ring cavity is analyzed with approximative methods. The design of the cavity and optimization of its dimensions are also given. The measured results of a test model is coincident with the calculated ones fairly.更多还原
