Abstract :
The emittance growth due to parasitic collisions in Tevatron was studied. It was found that the dominant long-range beam-beam effect is from the coupling resonance. A correction of the linear coupling of the long-range beam-beam interactions and the coupled helix orbit can significantly reduce the emittance growth. High-order multipole compensation of the long-range beam-beam interactions could further improve the beam dynamics.
