Abstract :
This paper describes the development of a beam-pipe HOM absorber, which is used to damp higher order modes (HOMs) of accelerating cavities for the ATF damping ring (DR). This device is a short beam pipe equipped with a microwave absorber. The requirement for the absorber, to search for an absorbing material, and the design of a prototype absorber-pipe are presented
