Abstract :
A series of beam tests using TRISTAN Accumulation Ring (AR) was dedicated to verify the feasibility of RF system and other components planned for KEKB, the B Factory project at KEK. In this paper, we describe the results on higher order mode (HOM) absorbers used for superconducting cavities (SCC). The absorber was manufactured by HIPping of ferrite powder onto Cu tube. The SCC system was operated stably with HOM´s being damped, and up to total of 4.2 kW was absorbed through the absorber without any problem
