Abstract

We have developed a radio-frequency (RF) power divider that is used for an RF distribution system in high-energy electron storage rings. This power divider has four waveguide ports, and it can split a high RF power by a ratio of 1:2 at an operating frequency of about 508.6 MHz. Since other properties are very similar to those of a magic-T it is very suitable for accelerator applications. By combining this device with a conventional magic-T, one can design an RF distribution system in which three cavities are driven by a single klystron. The design procedure of the power divider, a low-power measurement, and a high-power test result are presented
