Abstract

In this paper, a novel sub-terahertz (THz) extended interaction klystron (EIK) is presented. With the help of a three-dimensional (3D) particle-in-cell (PIC) simulation, design and optimize geometry of THz EIK is performed, which is composed of ladder loaded rectangular waveguide. In present work, the operation center frequency of THz EIK is 94.5GHz, and the CW out power 524W is achieved, the efficiency and bandwidth reaches 4.7% and 230MHz, with gain of 41dB, which is operating at voltage and beam current is 16 kV and 0.6A, respectively.
