Abstract
We report on recent enhancements to the physics modules of the ORBIT Code and on progress toward a new implementation of ORBIT using python. We have developed the capability to track particles through general three dimensional electromagnetic field configurations. This facility has proved essential in modeling beam transport through the complicated magnetic field regions of the SNS injection chicane and injection dump line, where beam losses are high. We have also enhanced the acceleration module to provide more flexibility for synchrotron calculations and we have developed alternative multiple Coulomb and Rutherford scattering models for the stripper foil and collimation routines. Finally, progress continues on the migration of the ORBIT physics models to a python user environment. We present the status of this work.
