Several beam intercepting devices (BID) are used in particle accelerators for different functions: machine protection (stopping the beam in accidental scenarios), human safety , beam conditioning (e.g. collimators, scrapers, slits), secondary beam production (targets) and absorbers (beam dumps). Since these devices are found in accelerators with a broad range of beam energies and particle types, a large diversity of requirements, materials and designs are observed. Typical considerations are physical and structural properties of materials. Hence, the full palette of materials is used in BIDs across the different accelerators, from ceramics and carbon-based materials (graphite and CfC) to virtually all metals. In addition, some devices need to absorb and manage power (heat) deposited by the beam, which imposes other constraints in the design, like cooling requirements and service temperature of the materials employed. Irradiation damage is also accounted for in the design of some devices. A state of the art of BIDs used in different accelerator complexes in the world will be presented here, including their main functionalities, requirements and design features.
