Ferrite is a well-known material for effectively absorbing electromagnetic waves, and ferrite blocks are used in accelerators as higher-order modes (HOM) absorbers in vacuum beam pipes. However, one of difficulties in using ferrite for this purpose is its weak bonding to the metal beam pipes, leading to a poor heat transfer rate. Herein we report the fabrication of ferrite-copper blocks using the spark plasma sintering (SPS) technique in which the ferrite powder is directly sintered on the copper block. This ferrite-copper block fabricated via SPS can be directly brazed or welded to other desired metals or directly to the beam pipes. Copyright © 2016 CC-BY-3.0 and by the respective authors.
