Title: ORBIT INJECTION DUMP SIMULATIONS OF THE H0 AND H- BEAMS

Abstract

Simulations of the transport of H0 and H- beams to the Spallation Neutron Source (SNS) ring injection dump are carried out using the ORBIT code. During commissioning and early operations, beam losses in this region have been the highest in the accelerator and have presented the most obvious hurdle to cross in achieving high intensity operation. Two tracking models are employed: 1) a piecewise continuous symplectic representation of the lattice elements in the injection chicane and dump line, and 2) particle tracking in full 3D magnetic fields, as obtained from OPERA code evaluations. The physics models also include estimations of scattering from both the primary and secondary stripper foils, and beam losses due to apertures throughout the beam line.
