LHC Fixed Target


Several proposals for fixed-target (FT) physics experiments at the LHC have been actively studied by interested communities. The use of splitting of beam halos from the core with bent crystals for internal targets and the use of internal gas (possibly polarised), or solid targets, were considered. Following the first PBC-FT report to the update of the European Strategy for Particle Physics (ESPP) and the subsequent recommendations, the working group will continue investigating FT proposals and conduct the relevant R&D to provide, as much as possible, the necessary support towards the evaluation of their technical feasibility.
