Title LHC circulating beam accidents for near-beam detectors
Contributors
Abstract The LHC stored beam contains 362 MJ of energy at the top beam energy of 7 TeV, offering considerable risk to the accelerator components and detectors of the machine. In this work, beam accident scenarios for the stored beam are considered which can present a danger for the near- beam moveable detectors of LHCb and TOTEM. Failures of the circuits powering dipoles and quadrupoles and impact of the beam are calculated, along with the possible quench of superconducting magnets. It is shown the moveable detectors are in the shadow of the collimation system, relying on the correct positioning and phase of collimating elements. The possible impact of rescattered protons is discussed. Also considered is the danger to the near-beam experiments from local closed bumps, which can significantly reduce the available aperture at the near-beam experiments and cause direct beam strike if unmonitored. Finally, conclusions are drawn, along with prospects for future studies.
