SYNCH, its status and its recent use at SSCL

SYNCH is a computer program for use in the design and analysis of synchrotrons, storage rings, and beamlines. The first accelerator program to organize its input in the form of a language, SYNCH provides a natural way to describe and design lattices and to analyze them through calculations of betatron functions, dispersion, beam envelopes, emittances, and closed orbits. In addition, particle tracking, non-linear transformations, misalignments, electron integrals, and orbit corrections may be treated. A brief summary of some features of the program and recent applications for designing the Interaction Regions (IR) of the SSC will given.
