About Us

LMY Technology has been serving the needs of businesses, both large and small, for over a decade. Lloyd Young has been providing consulting services on Accelerator technology for over 2 decades. TStep is an accelerator simulation code written by Lloyd Young. Documentation and user manual is written by James Billen.

TStep is an electron-linac particle-dynamics code. It is a versatile multi-particle code that transforms the beam, represented by a collection of particles, through a user-specified linac and/or transport system. It includes options for 2-D and 3-D space-charge calculations. TStep integrates the particle trajectories through the fields. This approach is especially important for electrons where some of the approximations used by other codes (e.g. the “drift-kick” method commonly used for low-energy protons) would not hold. TStep works equally well for electrons, positrons, ions, or mixtures of different species. TStep can read field distributions generated by either Fish for rf problems or Poisson for magnet problems and electrostatic problems.
