Abstract :
The recent status of the R&D on a damped structure cavity being developed at ISSP and Photon Factory is presented. For the cavity, the higher-order modes (HOMs) damping is obtained with the large beam duct, a part of which is made of sintered SiC. A prototype cavity has been built and tested at low power levels. It was confirmed that the HOMs, which can propagate out of the cavity through the beam duct, were strongly damped by the SiC duct. Recently, fabrication of a high power model has been completed. High power conditioning of the model is now prepared
