Beam-beam Effects in the Tevatron Run II / Shiltsev, Vladimir ; Alexahin, Yuri ; Lebedev, Valeri ; Lebrun, Paul ; Moore, Ronald ; Sen, Tanaji ; Valishev, Alexander ; Zhang Xiao Long
The Tevatron in Collider Run II (2001-present) is operating with many times higher beam intensities and luminosities than in previous Run I (1992-1995). Electromagnetic long-range and head-on interactions of high intensity proton and antiproton beams have been significant sources of beam loss and lifetime limitations. [...]

Computational Study of the Beam-Beam Effect in Tevatron Using the LIFETRAC Code / Valishev, Alexander ; Alexahin, Yuri ; Lebedev, Valeri ; Shatilov, Dmitry
Results of a comprehensive numerical study of the beam-beam effect in the Tevatron are presented including the dependence of the luminosity lifetime on the tunes, chromaticity and optics errors. These results help to understand the antiproton emittance blow-up routinely observed in the Tevatron after the beams are brought into collision. [...]

Improving the Tevatron Collision Helix / Moore, Ronald ; Alexahin, Yuri ; Johnstone, John ; Sen, Tanaji
In the Tevatron, protons and pbars circulate in a single beam pipe, so electrostatic separators are used to create helical orbits that separate the two beams except at the two interaction points (IP). Increasing the separation outside of the IPs is desirable in order to decrease long range beam-beam effects during high energy physics (HEP) stores. [...]

LIFETRAC Code for the Weak-Strong Simulation of the Beam-Beam Effect in Tevatron / Valishev, Alexander ; Alexahin, Yuri ; Lebedev, Valeri ; Shatilov, Dmitry
A package of programs for weak-strong simulation of beam-beam effects in hadron colliders is described. Accelerator optics parameters relevant to the simulation are derived from beam measurements and calculations are made using OptiM optics code [...]

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. [...]
