In this paper, the design of a Ku-band 110-kW gyrotron traveling wave tube (gyro-TWT) amplifier with the operating mode TE11 is presented. The optimum interaction structure circuit of the gyro-TWT with distributed wall losses is derived from the self-consistent nonlinear code on the basis of the dispersion relationship and the linear theory. The effects of the parameters such as input power, driver...
A high power gyrotron traveling-wave amplifier operating in the low-loss TE01 mode has been designed. The amplifier will be driven by a 70-kV, 10-A electron beam with a pitch angle (vperp/v//)of unity and velocity spread of 3~5% generated by a double-anode magnetron injection gun (MIG).The amplifier is predicted by nonlinear theory simulation code to generated 180 kW at 35 GHz with 25 efficiency,...
High-power coherent millimeter-wave sources have been extensively studied for many applications including high-resolution radars, millimeter-wave electronic counters measures, material processing, and high- energy particle accelerators. This paper presents some recent experiment results in the development of this gyroklystron at IECAS.
The rule of mode coupling and mode competition in helical wave-guide are analyzed according to the coupling wave equations of it. The selection of operating point is discussed. These provide basis for the calculation of beam-wave interaction.
