The review of the simulations tools used for the Spallation Neutron Source (SNS) linac tuning and beam dynamics studies is presented. The usage and comparison of the different approaches like single-particle, envelope, particle-in-cell and codes for particular tasks is discussed. The used codes include Parmila, Impact, Track, XAL online model, and a linac model based on the pyORBIT ring code. The future code development for SNS linac is suggested.

The overview of the Spallation Neutron Source (SNS) linac lattice, diagnostics, and beam dynamic is presented. The models and model based tuning procedures of the warm and superconducting parts of the SNS linac are discussed. There are significant discrepancies between predicted by simulations and measured losses in the superconducting part of the linac. The possible reasons for these losses and their relation to the beam dynamics are discussed.
