Description
After briefly discussing sources of imperfections, we characterize them
in terms of dipole, quadrupolar, and skew quadrupolar errors and move
on to discuss how these imperfections are modeled in beam dynamics codes.
We continue by reviewing the concepts of dispersion and chromaticity and
explain how they are measured before turning to imperfections that are
caused by multipoles, in particular, by feed-down. We conclude by addressing
errors that are introduced by imperfect diagnostic equipment such as
misaligned position monitors and mention means of how to identify this
problem.
