Abstract

Beam halo is a big challenge for high intensity accelerators. Knowledge of the mechanisms of halo formation could help to prevent it. The Spallation Neutron Source (SNS) Beam Test Facility (BTF) is a functional duplicate of the SNS front end with enhanced diagnostics capable of accelerating 50 mA H- or protons to 2.5 MeV. To explore halo development in both matched and mismatched beams, a dedicated FODO lattice is being designed as an extension to the BTF. The FODO lattice will be 3.5 meters in length and is comprised of 16 quadrupole magnets, with dedicating matching magnets. Simulations of the design lattice show halo can be seen clearly in the phase space density plot when beam is mismatched. Details of the FODO design will be presented in the paper.
