Beam Test Results on HOM Absorber of Superconducting Cavity for KEKB
Abstract
In 1996, three series of beam tests were performed on the superconducting cavity for KEKB in TRISTAN Accumulation Ring. The cavity had two higher-order-mode absorbers made of ferrite on the upstream and downstream sides. In the tests, the absorbed power went up to 4.2 kW in total without problems. There were no changes on absorbing characteristics during the beam tests. Loss factor of the system was measured at 1.5 to 9 cm bunches and was in good agreement with theoretical predictions. Details of the tests and results will be shown.
