High power rf systems were in operation stable. Two 300 kW klystrons along with the key waveguide components were tested before feeding rf power into 1.3 GHz 9-cell superconducting cavities. The rf high power variable divider and 360 degree waveguide phase shifters are working successfully. The simulations on different waveguide structures for the power dividers, phase shifters have been studied. The comparisons of the calculation results are reported in the paper. The rf signal level tests of the components and waveguide distribution systems will also be present in this paper.
