Restoring the Skew Quadrupole Moment in Tevatron Dipoles / Harding, David J ; Bauer, Pierre ; Blowers, James N ; Di Marco, Joseph ; Glass, Henry ; Hanft, Ray ; John, Carson ; Robotham, William ; Tartaglia, M ; Tompkins, John et al.
In early 2003 it was realized that mechanical changes in the Tevatron dipoles had led to a deterioration of the magnetic field quality that was hindering operation of the accelerator. After extensive study, a remediation program was started in late 2003 which will continue through 2005. [...]

Reshimming of Tevatron Dipoles; A Process-Quality and Lessons-Learned Perspective / Blowers, James N ; Hanft, Ray ; Harding, David J ; John, Carson ; Robotham, William
Over the last two years corrections have been made for the skew quadrupole moment in 530 of the 774 installed dipoles in the Tevatron. This process of modifying the magnets in situ has inherent risk of degrading the performance of the superconducting accelerator. [...]

New Pulsed Orbit Bump Magnets for the Fermilab Booster Synchrotron / Lackey, James ; Harding, David J ; John, Carson ; Kashikhin, Vladimir ; Makarov, Alexander ; Prebys, Eric
The beam from the Fermilab Linac is injected onto a bump in the closed orbit of the Booster Synchrotron where a carbon foil strips the electrons from the Linac’s negative ion hydrogen beam. Although the Booster itself runs at 15Hz, heat dissipation in the orbit bump magnets has been one limitation to the fraction of the cycles that can be used for beam. [...]

A New Correction Magnet Package for the Fermilab Booster Synchrotron / Kashikhin, Vladimir ; Harding, David J ; John, Carson ; Lackey, James ; Makarov, Alexander ; Pellico, William ; Prebys, Eric
Since its initial operation over 30 years ago, most correction magnets in the Fermilab Booster Synchrotron have only been able to fully correct the orbit, tunes, coupling, and chromaticity at injection (400MeV). We have designed a new correction package, including horizontal and vertical dipoles, normal and skew quadrupoles, and normal and skew sextupoles, to provide control up to the extraction energy (8GeV). [...]

Deterioration of the Skew Quadrupole Moment in Tevatron Dipoles Over Time / Syphers, Michael J ; Harding, David J
During the 20 years since it was first commissioned, the Fermilab Tevatron has developed strong coupling between the two transverse degrees of freedom. A circuit of skew quadrupole magnets is used to correct for coupling and, though capable, its required strength has increased since 1983 by more than an order of magnitude. [...]
