四腔相对论速调管放大器的实验研究
Experimental Study on a Four-Cavity Relativistic Klystron Amplifier
摘要
Abstract
A four-cavity high gain relativistic klystron amplifier is developed on the basis of a three-cavity relativistic klystron. The mode control in a four-cavity relativistic klystron is studied theoretically together with particle in cell (PIC) simulation in the paper. And special methods are taken to suppress the nonworking mode’s oscillation in the device which has an input cavity with low interaction impedance, ladder structured drift and etc. By optimizing the output cavity gap in PIC simulations, the output power of 3.05 GW and the gain of 63 dB (the seeding rf power 1.5 kW) of the discussed microwave structure are achieved. Finally the gain of 61.4 dB (the seeding rf power 1.38 kW) is achieved in the experiment, and its pulse duration is more than 100 ns.关键词
