Collective beam-beam effects in hadron colliders can cause slow beam-size growth and unstable centroid oscillations. Simulations show that feedback control can suppress these effects, improving collider performance.

Area of Science:

  • High-energy physics
  • Accelerator physics

Background:

  • Collective beam-beam effects are crucial in hadron colliders.
  • Understanding these effects is vital for maximizing luminosity.

Purpose of the Study:

  • To investigate collective beam-beam effects in the CERN Large Hadron Collider.
  • To analyze the impact of multipole field errors and beam-beam interactions on beam dynamics.

Main Methods:

  • Utilized a strong-strong beam-beam simulation.
  • Incorporated multipole field errors and interactions at two high-luminosity points.

Main Results:

  • Identified two distinct beam dynamics: slow beam-size growth and unstable centroid oscillation.
  • Observed chaotic transport characteristics in centroid oscillations.

  • Found a threshold for the beam-beam parameter below which instability was not observed.
  • Noted that escape rate increases with nonlinear field errors.

    • Conclusions:

    • Beam-centroid oscillation significantly enhances beam-size growth.
    • Feedback control to eliminate centroid motion can effectively suppress beam-size growth.
    • No steady state of coherent beam-beam oscillation was observed.
