Abstract :
The Development of the 10MW L-band multibeam klystron was started in the Institute of Electronics, Chinese Academy of Sciences (IECAS) three years ago. The electrical and structural designs for this klystron have been accomplished , in which many technical problems have been resolved. In the design of electron optical system, the uniform field multiple-lens focusing scheme was adopted, by which the paraxial multi-beams with good laminarity and fluctuation were obtained. In the design of beam-wave interaction system, the second harmonic cavity was used to enhance the beam-wave interaction efficiency and reduce the volume and weight of the klystron. Nowadays, the prototype is being fabricated and will be finished in one or two months. This paper presents the research progress on the 10MW L-band multi-beam klystron and the key technical issues resolved in detail.
