  • New beam dump design for High-Luminosity stored beam energies

    New beam dump design for High-Luminosity stored beam energies

    In the LHC beam dumps, the energy stored in the proton beams must be safely absorbed by the core materials. Due to their exceptional thermal shock and radiation resistance, carbon-based materials have been successfully used for this purpose since LHC Run 1. In the High-Luminosity (HL) era, the maximum stored energy in each LHC beam…
