Abstract :
The preliminary design of a four-cavity G-band sheet-beam Extended-Interaction Klystron (EIK) Circuit is presented. The circuit design has been performed with the self-consistent particle-in-cell (PIC) code MAGIC-3D. All cavities operate in the 2-pi mode. The circuit is powered by a 520 mA, 16.5 kV sheet-electron beam. Output power of 453 W is achieved with an input power of 25 mW, corresponding to an electronic gain of 41.6 dB in a circuit length of approximately of 1.2 cm.
