Abstract :
To increase an electric field symmetry in a coupler cavity, a very simple structure of a two-iris coupler cavity was proposed by H. Matsumoto in 1994. The MAFIA 3D code is useful to simulate Slater´s tuning curve method, which is used to determine the dimensions of the coupler cavity such as iris aperture and cavity diameter. It was find that MAFIA simulation results show that two-iris method will realize a good symmetrical electric field with a very simple structure as well as no difficulties for fabrication. This type of double feed coupler will be used for a Choke-mode type damped accelerating structure at C-band (5712 MHz) and an rf-gun for a linear collider
