Abstract
The beam-wave interaction of rectangular helix traveling-wave-tube (TWT) is simulated by MAGIC. Two linearly tapered resistance couplers were applied to reduce reflections, which may replace the actual input and output structures and reduce the self-excitation phenomena. The results show that the computing model is effective to simulate the beam-wave interaction of the rectangular helix TWT. Then some nonlinearly interaction phenomena and parameters of a designed X-band rectangular helix TWT were analyzed, such as the electron bunching, the energy exchange and the output power. And the operating frequency of the designed rectangular helix TWT is from 8 to 12 GHz, the highest output power reaches 480 W, bandwidth is about 4 GHz, and the interaction efficiency is 11.8 %.
