LHC Fixed Target

Mandate

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.

Objectives

Validation of operational scenarios for the operation of SMOG-2 with noble and getterable gases and conceptual design of a polarized gas target with a storage cell.

Development of a set-up and operational scenario for fixed target physics by extraction of the beam halo using single and double crystal configurations. Conceptual design report.
