The Studies of X-Band Hybrid Dielectric-Iris-Loaded Accelerating Structure

The dispersion property and the propagation characteristic of the accelerating mode (TM01mode) about a X-band (f=9.37GHz) hybrid dielectric-iris-loaded accelerating structure has been analysed and discussed by the field matching method and Mafia code respectively. The ones of the HEM11mode have also been calculated by MAFIA code. Based on the experimental results of the used dielectric (ceramic). Mafia code has been used to make the optimization design for the new structure. Some model cavities have been developed and measured. The experimental investigations show that the results are nearly agreement with the theory design.
