TEAPOT: A thin-element accelerator program for optics and tracking

The program TEAPOT is intended for fast and exact particle tracking in an accelerator with magnet errors and misalignments. The formalism uses only thin elements, but, unlike other 'kick' codes, TEAPOT tracking is exact to all orders in all six phase-space displacements. This procedure of exact tracking in an approximate lattice can be contrasted with approximate tracking in an 'exact' lattice, as is performed in existing programs. TEAPOT also has provisions for a full Twiss analysis after errors and misalignments have been added and for the compensation of error-induced coupling, tune-shifts, and chromaticity shifts. (author)
