Beam Intercepting Devices at CERN – Types, Challenges, Design, R&D and Operation

Where:  

222/R-001 at CERN

Beam-intercepting devices in the CERN accelerator complex include beam collimators, particle producing targets, beam dumps and absorbers, beam stoppers, passive masks, slits as well as scrapers. The lectures will focus on the engineering activities regarding these devices, which consistin conceptual studies, material selection, prototyping and testing, R&D, design, manufacturing, installation and operation follow-up. Examples of recently developed devices will be shown, including fixed targets, collimators and dumps/absorbers to cope with LIU and HiLumi beams. Design work includes Fluka and thermo-mechanical simulations to determine the energy deposited by the beam in the absorbing materials, testing and prototyping activities to validate technical solutions, material characterisation and testing under beam (HiRadMat tests). Manufacturing, assembly, installation and operation follow-up will be shown for some devices, in order to illustrate the challenges related to each of device.
