Studies of the Chromaticity, Tune, and Coupling Drift in the Tevatron / Martens, Michael A ; Annala, Jerry ; Bauer, Pierre ; Shiltsev, Vladimir ; Velev, Gueorgui
Chromaticity drift is a well-known and more or less well-understood phenomenon in superconducting colliders such as the Tevatron. Less known is the effect of tune and coupling drift, also observed in the Tevatron during injection. [...]

Measurements of Field Decay and Snapback Effect on Tevatron Dipole and Quadrupole Magnets / Velev, Gueorgui ; Ambrosio, Giorgio ; Annala, Gerald ; Bauer, Pierre ; Carcagno, Ruben H ; Di Marco, Joseph ; Glass, Henry ; Hanft, Ray ; Kephart, Robert ; Lamm, Michael J et al.
Since the beginning of 2002 an intensive measurement program has been performed at the Fermilab Magnet Test Facility to understand dynamic effects in the Tevatron magnets. Based on the results of this program a new correction algorithm was proposed to compensate for the decay of the sextupole field during the dwell at injection and for the subsequent field "snapback" during the first few seconds of the energy ramp.

Landau Damping of the Weak Head-Tail Instability at Tevatron / Ivanov, Petr M ; Alexahin, Yuri ; Annala, Jerry ; Lebedev, Valeri ; Shiltsev, Vladimir
Landau damping of the head-tail modes in Tevatron beam with the help of octupole-generated betatron tune spreads permits to reduce chromaticity from 15-20 units to zero thus significantly improving the beam lifetime. The octupole strengths have been experimentally optimized at different stages of the Tevatron operation, from proton injection to collision. [...]

Tevatron Alignment Issues 2003-2004 / Volk, James T ; Annala, Jerry ; Elementi, Luciano ; Gelfand, Norman M ; Gollwitzer, Keith ; Greenwood, John A ; Martens, Michael A ; Moore, Craig D ; Nobrega, Alfred ; Russell, Allison D et al.
It was observed during the early part of Run II that dipole corrector currents in the Tevatron were changing over time. Measurement of the roll for dipoles and quadrupoles confirmed that there was a slow and systematic movement of the magnets from their ideal position. [...]
