Abstract :
Two types of sintered SiC (silicon carbide) ceramics have been developed and applied as the HOM absorbers for the second prototype ARES cavity (ARES96). One is bullet-shape SiC ceramics and the other is a tile one. The prototype cavity equipped with these absorbers was successfully tested with an electron beam in the TRISTAN accumulation ring. High power tests of these absorbers were carried out using an L-band RF power source. The HOM absorber designs and the results of the tests are discussed
