Helix TWTs are one of the important components in communication systems, radar, medical systems and scientific research areas. Using the finite element method, a software package named Thermal Simulator (TS) which is a part of Microwave Tube Simulator Suite (MTSS) and can be used for thermal analysis of Helix Slow-Wave Structure was developed. To validate TS, numerical results for a helix slow-wave...
This paper provides the design and realization of high frequency circuit simulator (HFCS) which is based on the finite element method. For vilification, the cold-test characteristics of two actual helical slow wave structures have been calculated and the results were found to be consistent with those of HFSS simulation with same mesh density.
A simulated model has been established to calculate the temperature of helical slow-wave circuits accurately. The Finite Element Method software ANSYS was used to analyze the thermal distortion of the helical slow-wave circuit of TWT. The thermal analysis results show the thermal stress makes helical tape concave at the positions contacting with rods and convex at the part between the two rods, and...
