Abstract :
Strategies for tuning and correcting aberrations that arise as the real Final Focus Test Beam (FFTB) lattice departs from the design lattice are presented. The following beam-based tuning and alignment strategies are examined: quadrupole alignment, quadrupole tuning, sextupole pair alignment and tuning, and stability of CCX, CCY, and final doublet. The tuning of the incoming beam is considered with regard to alpha and beta matching, incoming dispersion, and incoming coupling.<>
