IntroductionSubdirectories of the Trace directory on this file server contain source and executable code for Trace 3-D and Trace 2-D programs. Trace 3-D is an interactive beam-dynamics program that calculates the envelopes of a bunched beam, including linear space-charge forces, through a user- defined transport system. Trace 3-D provides an immediate graphics display of the envelopes and the phase-space ellipses and allows nine types of beam-matching options. The transport system may contain drifts, thin lenses, quadrupole lenses, solenoids, double or triplet lenses, bending magnets, rf gaps or cavities, radio-frequency-quadrupole cells, coupled-cavity linac sections, and user-defined elements. This software is provided by the Los Alamos Accelerator Code Group (LAACG) of Los Alamos National Laboratory. The software is being provided for your personal use. To help us to document who uses this software, we ask that you do not distribute copies of the software outside your own group or department. Acknowledgments/VersionsThe Trace codes were written by Ken Crandall. A conference paper [Dan Rusthoi, Walter Lysenko, and Ken Crandall, "Further Improvements on Trace 3-D," Proceedings of the 1997 Particle Accelerator Conference (Vancouver, May 12-16, 1997)] discusses a 1997 version intended to run on any platform. The source code for this version is available on this FTP server in directory Trace\OtherVersions\Source1997. The LAACG experience has been that this "universal" version of Trace is very difficult to implement and it is essentially unsupported. The LAACG distributes executable code for Windows and Linux as discussed below. DocumentationThe 1997 Trace manual is available in PDF and Microsoft Word formats. Also copies of the 1997 Particle Accelerator Conference paper in several formats (PS, PDF and MS Word) are available. Supported VersionsSubdirectories Windows and Linux contain the latest version of Trace 3-D for these two platforms. These two versions originate from the same source files. The Windows code is compiled with Lahey Fortran LF90 and Winteracter. The Linux code uses Lahey Fortran LF95 and Winteracter for Linux. Instructions for using the commands are contained in the program menu. We recommend as a useful reference the manual "Trace 3-D Documentation," (LA-UR-97-886) by K. R. Crandall and D. P. Rusthoi in directory Trace\DOC. Each subdirectory contains a copy of the example files. Linux compilers will usually link the executable with the shared version of the Motif library. Distributing a dynamically linked executable means that the end users require a compatible version of that library. This would complicate installation and configuration of Trace3d on the end user's system, if they do not have the same version of the Motif shared library. To avoid this requirement Trace3d was linked statically. Reporting BugsWe would appreciate hearing from you if you discover a bug or if you have suggestions for improvements we might make in the codes. We already have added several features suggested by users. Trace DownloadNote: If you are a user of Parmela, Parmila, or the RFQ Design Codes, then you will not need to download the Trace codes separately unless you need this code for different platforms. The Setup program for Parmela, Parmila, and the RFQ Design Codes will install Trace 3-D for Windows, documentation in both PDF and Microsoft Word formats, and several Trace example files.
