TI - Accelerator Challenges at ESS J2 - Proc. of HB2023, Geneva, Switzerland, 09-13 October 2023 CY - Geneva, Switzerland T2 - ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams T3 - 68 LA - english AB - The European Spallation Source (ESS), undergoing concurrent installation, testing and beam commissioning in Lund, Sweden, will be the brightest source of cold neutrons once the driving proton linac reaches the intermediate energy of 800 MeV and a power of 2 MW. The final goal of ESS is to deliver a 2 GeV beam of protons with an average power of 5 MW to target. The high brightness of the neutron source is achieved by optimization of the rotating tungsten target and the innovative butterfly neutron moderator. The high beam power of the linac demands high-quality beam production, efficient acceleration, and near lossless transport of a high current beam. All of these impose strict requirements on the design and beam commissioning of this machine. The linac is being commissioned in several steps as the installation progresses. This talk presents the status of the project, challenges in the accelerator and updates on the beam commissioning. PB - JACoW Publishing CP - Geneva, Switzerland ER -
