Multiphysics and Multipactor Analyses of TE022-Mode High-Power X-Band RF Window

Popis výsledku v původním jazyce

This letter presents the design of an overmoded X-band RF window for use in high-power microwave tubes, such as klystron, magnetron, and linear accelerator (LINAC). The cylindrical section of the window containing dielectric barrier operates in the TE 022 mode. Conversion from TE 10 mode to TE 022 mode is achieved using four rectangular slots made on the narrow walls of the rectangular waveguide sections. The simulation results for the proposed design in CST and HFSS are in good agreement. The return loss, insertion loss, and bandwidth are obtained as 52.76 dB, 0.06 dB, and 41.4 MHz, respectively, at 9.3 GHz. Coupled electromagnetic, thermal, and structural simulations are performed to study the multiphysics performance of the RF window. The multipactor analysis is carried out in SPARK3D to determine the multipactor threshold. The proposed TE 022 mode RF window can operate safely at a 20.75 MW of peak power.
