	At the European Spallation Source (ESS) in Lund (Sweden), the commissioning of the high-power normal conducting linac started in 2018. This paper deals with the beam destinations for the commissioning phases with initially the proton source and LEBT, then the MEBT and lately four DTL sections. The beam destinations were designed to withstand the ESS commissioning beam modes (with proton current up to 62.5mA, pulse length up to 50E-6s and repetition rates up to 14Hz). The EPICS-based control system allows measurements of the proton current and pulse length in real-time; it controls the motion and the power suppliers, and it also monitors the water cooling systems. Special focus will be on the results of thermo-mechanical simulations in MCNP/ANSYS to ensure safe absorption and dissipation of the volumetric power-deposition. The devices’ materials were chosen not only to cope with the high-power proton-beam, but also to be vacuum-compatible, to minimize the activation of the beam destinations themselves and the residual dose nearby. The results of neutronics simulations will be summarized with special focus on the shielding strategy, the operational limits and relocation procedures.

At the European Spallation Source (ESS) in Lund (Sweden), the commissioning of the high-power normal conducting linac started in 2018. This paper deals with the beam destinations for the commissioning phases with initially the proton source and LEBT, then the MEBT and lately four DTL sections. The beam destinations were designed to withstand the ESS commissioning beam modes (with proton current up to 62.5mA, pulse length up to 50E-6s and repetition rates up to 14Hz). The EPICS-based control system allows measurements of the proton current and pulse length in real-time; it controls the motion and the power suppliers, and it also monitors the water cooling systems. Special focus will be on the results of thermo-mechanical simulations in MCNP/ANSYS to ensure safe absorption and dissipation of the volumetric power-deposition. The devices’ materials were chosen not only to cope with the high-power proton-beam, but also to be vacuum-compatible, to minimize the activation of the beam destinations themselves and the residual dose nearby. The results of neutronics simulations will be summarized with special focus on the shielding strategy, the operational limits and relocation procedures.
