COSY INFINITY is an arbitrary order beam dynamics simulation and analysis code. It allows the study of accelerator lattices, spectrographs, beamlines, electron microscopes, and many other devices. It can determine high-order maps of combinations of particle optical elements of arbitrary field configurations. The elements can either be based on a large library of existing elements with realistic field configurations including fringe fields, or described in detail by measured data.

Analysis options include computation of high-order nonlinearities; analysis of properties of repetitive motion via chromaticities, normal form analysis, and symplectic tracking; analysis of single-pass systems resolutions, reconstructive aberration correction, and consideration of detector errors; and analysis of spin dynamics via computation of spin maps, spin normal form and spin tracking.

UNIX, it works under RedHat Linux (4.2 and 5.0) using f2c/fort77. The authors are also developing a X-Windows interface using PGPlot. Currently, the program supports ASCII, Postscript, LaTeX and Xterm (Tektronix) under Linux. The Linux related questions should go to Jens Hoefkens.
