Abstract

We have studied a multi-mode Delay Line Distribution System (DLDS) as the RF power distribution system from klystrons to RF structures for linear colliders. In particular, a 2×2 DLDS has been proposed and studied at KEK for Japan Linear Collider (JLC). It has been proved that the 2×2 DLDS is simple, bus has good transmission efficiency. We have designed RF components of a basic unit of a DLDS using the High Frequency Structure Simulator (HFSS) code. They include the TE₀₁ extractor, the TE₁₁ to TE₀₁ converter, and the TE₁₁ to TE₁₂ converter for TE₁₂ mode. HFSS calculation of the system, which consists of TE₀₁ extractor and TE₁₁ to TE₀₁ converter, shows that the transmission efficiency of each mode is better than 95%. The components, as well as the system are being studied experimentally. A low power test model for the mode stability experiment in 55 m long wave guide in DLDS is also being developed
