Abstract

Abstract

This paper introduces a technical scheme of X-band high peak power klystron. At present, this klystron has achieved 50 MW pulse output power and 57% efficiency at X band. The pulse width is up to 3.6 μs. By using some key techniques, such as COM method, circle waveguide travelling-wave window, Anticorona ring and coating thin film on ceramic, some problems such as high efficiency, high peak power capacity and high reliability are solved. In particular, COM method can be used to optimize electron beam bunching. Compared with the second harmonic bunching method, the interaction efficiency can be further improved by about 10% under the same length of high frequency tube body. Because of the successfully developed klystron, the peak power level of domestic X-band klystron has been raised from 3 MW to 50 MW, and the performance of the klystron has reached the international leading level.
