Beam-based alignment of quadrupole and sextupole magnets is crucial for the overall performance of linear collider final focus systems, especially for elimination of backgrounds and higher-order aberrations. At the Final Focus Test Beam (FFTB), alignment tolerances required for achieving the desired spot size are 100 microns in the horizontal and 30 microns in the vertical. Using a combination of independent magnet power supplies, hi-h-resolution stripline beam position monitors and precision magnet movers, the FFTB can be aligned to these tolerances in about 8 hours. Description of the algorithm, presentation of alignment results, and possible improvements to the system are discussed.
