Abstract :
For the Fermilab Tevatron low beta insertions installed in 1990-1 as part of a luminosity upgrade, approximately 35 superconducting cold iron quadrupoles were built utilizing a two-layer cos 2 theta coil geometry with a 76-mm-diameter. The field harmonics and strengths of these magnets, determined by measurement at cryogenic conditions, are presented. Evidence for a longitudinal periodic structure in the remanence field is shown.<>
