    "abstract": "We present a study of orbit jitter and emittance growth in a long linac\ncaused by misalignment of quadrupoles. First, assuming a FODO lattice, we\nderive analytical formulae for the RMS deviation of the orbit and the emittance\ngrowth caused by random uncorrelated misalignments of all quadrupoles. We then\nconsider an alignment algorithm based on minimization of BPM readings with a\ngiven BPM resolution and finite mover steps.",
