Their function is to protect the vacuum chambers from the high power density produced by the dipole magnets synchrotron radiation. In the EBS storage ring, the 430 kW total heatload will be stopped by 400 individual absorbers of twelve different types. In order to simplify their design and reduce their costs, a new material will be used (CuCr1Zr) associated with a novel design integrating the vacuum sealing flange in the CuCr1 absorber body and avoiding any brazed or welded junctions. This alloy, used for other applications (ITER-Fusion for Energy), offers an alternative to Glidcop with a very good compromise between thermal and mechanical characteristics. The exact location of each absorber is established through precise ray-tracing studies, which define the best place between the optical elements. The design of the absorbers will be described including technological aspects, together with the investigations on the CuCr1Zr material, the prototypes and tests carried out to validate the novel design choices.
