General description of the evacuated wave guide transmission line for the JET-EP ECRH project
The goal of this document is to provide a detailed description of the preliminary design and technical information of the proposed 63.5mm diameter, corrugated HE(11) evacuated transmission lines for JET-EP ECRH system. The JET-EP ECRH system envisions six to eight 1.0MW gyrotrons at 113.3GHz. The microwave power from a gyrotron is to be transmitted to the launcher of the tokamak via a transmission line. On average each line is 72m in length and includes 9 miter bends, two switches, a calorimetric load, pumpout tees, gate valves and DC breaks. The material contained within this document represents the design status as it stood upon the cancellation of the project in February 2002. The initial phase planned for the installation of six ECH units (power supply + gyrotron + transmission line + launcher) with the capability of an additional two units at 170GHz. The design was made for a total of eight lines, even though only six lines may be discussed in this document.
