Abstract :
Using thermal analysis results from Ansys and the experimental testing results for the slow wave structure of a 120W helix TWT, the varying scope of the thermal resistance value between the helix and rods is firstly obtained. In order to obtain the temperature distribution in the slow wave structure of a 500W helix TWT, the varying scope of thermal resistance from the 120W helix TWT is applied. Based on the above results, the thermal analysis for a 500W helix TWT is conducted and the helix´s over-heating problem is solved.
