Title: Short quadrupoles: Why the 12Q12 is not quite right
Abstract: "Normal" quads are those that are constant cross-section,
longer than their aperture, more-or-less truncated at each end. "short
quads have length approximately same as aperture. There is a pervasive
myth that short quads, being "all fringe field", have higher aberrations
than "normal" ones. This myth will be debunked. The analysis has
implications not only for our own "12Q12"s, but for any "normal" quad
design as well. Implications for the LHC beta-star IP quads are given as
an example.
