The intelligent graphics interface for particle opticsand accelerator design represents a new approach to softwaretools for analyzing high energy physics accelerators. Asophisticated graphical user interface (GUI), incorporatingexpert system features, will be combined with state-of-the-artcharged particle optics and accelerator simulation codes. Amodular structure allows the GUI and the simulation codes to becustomized to each class of accelerator or optics problem.Existing Fortran codes, as well as codes in other languages, canbe compiled and linked with the intelligent graphics interface.Particle optics, beamlines, and complete accelerator systems arebuilt using drag and drop icons in a window system developedspecially for particle optics modeling. The same beamlineproblems may be run using top-level scaling models, Lie algebraprograms, matrix and envelope codes, or multiparticlesimulations. Beamlines are moved from one computation model to 33 another simply by copying and pasting the icons from onewindow to another. A novel data translation algorithmautomatically converts the beamline representation to therequired format. In Phase I, a demonstration prototype of theGUI, integrated with several codes used in the design of highenergy accelerators, will be completed. Anticipated Results/Potential Commercial Applications asdescribed by the awardee: The intelligent graphics interface forparticle optics and accelerator design will prove a new softwaretool that improves scientific productivity in solving problemsassociated with design of particle accelerators and beamlines.The tool will equip scientists and engineers with newcapabilities for efficiently modeling and analyzing chargedparticle beamlines and accelerator systems.
