MAGIC3D simulations on overmoded W-band coupled-cavity traveling-wave tube
In this paper MAGIC3D Particle-in-cell (PIC) simulations of overmoded W-band coupled-cavity traveling-wave tube (CCTWT) are shown. The computational analysis of W-band coupled-cavity slow-wave structure was conducted using an electromagnetic CST-MWS, HFSS, and PIC code MAGIC3D. We investigated the large-signal and nonlinear beam dynamics of the W-band CCTWT using MAGIC3D. Simulations predict that the 86-cavity overmoded W-band CCTWT produces 290 W of saturated power with an input power of 0.5 W and a gain of 27.6 dB at 95 GHz when the beam voltage and current are set to 30 kV and 330 mA, respectively, under flat magnetic field of 2.5 kG along total 86 cavities. The saturated bandwidth is calculated to be 600 MHz from 94.6 GHz to 95.2 GHz. The overmoded TWT is a promising approach for high power operation at W-band TWT and higher frequencies TWTs application1.
