Abstract :
Candidates for the accelerating structure in realizing an operation in a multibunch mode in the Japan Linear Collider (JLC) are described. The external Q value of the TM110- pi mode in a damped structure with a slotted disk is very sensitive to the geometry. The damped structure with slots in the disk was found too sensitive to apply to the actual structure for the JLC. A damped structure of a crossed waveguide type was found to be a good candidate for the characteristics of the higher modes. A detuned structure with its frequency distributed similar to a truncated gaussian showed a good cancellation of a higher mode.<>
