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...
Consider the thermal contact resistance and the thermal conductivity as the function of temperature, the power dissipation of BeO and diamond-supported, the diamond-studded and the full-diamond helical slow-wave structures (HSWS) are computed using ANSYS. Results indicated the studded-diamond circuit is better than the diamond-support circuit. Especially, the full diamond circuit demonstrated advantage...
