| Abstract |
At the European Spallation Source, a 2 GeV, 5 MW proton beam will be delivered from a superconducting linear accelerator to target at a 4% duty factor, which poses demanding requirements on target station design. To tune the beam delivery system and to protect the target station components, the current density, the halo distribution, and the position of the proton beam shall be measured. To provide this functionality, a suite of beam monitoring devices will be deployed in the target monolith, including a multi-wire grid for the beam profile monitoring, thermo-couple assemblies and secondary emission blades for aperture monitoring, and a beam footprint imaging system consisting of optical components and luminescent coatings. Since these devices are exposed to particles that deposit energy and cause a high rate of radiation damage, it is a significant challenge to ensure full functionality. In this paper, material selection, lifetime estimates and operational criteria for these beam-monitoring devices are presented. A number of particle transport and finite-element simulations are performed for analyses, and an empirical validation plan is presented.
