Abstract :
A HOM (higher-order-mode) damped cavity for the ATF Damping Ring was designed at KEK. Damping both by waveguides and by big beam holes was adopted. Numerical calculations on external-Q´s of low-frequency HOMs showed good damping characteristics. Low-power measurements are under way with a cold-model cavity
