Abstract :A helical (Slow Wave Structure SWS) traveling wave tube (TWT) operating in the C bandwidth was designed using CST software. Based on modelling, TWT components were produced. Conductor support rod rings were used to matching the impedance line and provide ease of assembly. According to the modelling, the signal gain was determined as 30 dB. In addition, Time Domain Reflectometer (TDR) analyses were performed to observe the effect of mounting rings on impedance improvements with the help of software. As a result, it has been determined that the support rod rings, which have not been used before in C band helix TWT systems, positively affect the ease of assembly and impedance improvement.
