MARYLYE is a Fortran-language beam transport and tracking code developed at the University of Maryland which employs algorithms based on a Lie algebraic formalism for charged particle trajectory calculations and is designed to compute transfer maps for and trace rays through single or multiple beam-line elements. This is done without the use of numerical integration or traditional matrix methods; all nonlinearities, including chromatic effects, through third or octupole order are included. MARYLYE thus includes effects one order higher than those usually handled by existing matrix-based programs. Presently the following beam-line elements are described by MARYLYE: drifts; normal-entry and parallel-faced dipole bends; fringe fields for dipoles; hard-edged magnetic quadrupoles; fringe fields for quadrupoles; hard-edged magnetic sextupoles; hard-edged magnetic octupoles; axial rotations; RF bunchers; and a user specified transfer map through nonlinear terms of degree 3. Particle transport calculations, or ray traces, are carried out at speeds comparable to those of current matrix-based codes.
