Beam-energy inequality in the beam-beam interaction

Physical Review D, 1990
Conditions for energy transparency,'' unequal-energy beams having the same beam-beam behavior, are derived for round beams from a Hamiltonian model of the beam-beam interaction. These conditions are equal fractional betatron tunes, equal synchrotron tunes, equal beam-beam strength parameters, equal nominal sizes, equal {beta}{sup *}'s and equal bunch ...

Beam-Beam Instability in Case of Strong-Weak Beam-Beam Interactions

AIP Conference Proceedings, 2003
Beam‐beam effects in HERA were studied with a self‐consistent beam‐beam simulation by using the particle‐in‐cell method. A remarkable agreement between the experimental measurement and the simulation result was observed on the emittance growth, luminosity reduction, and coherent beam‐beam tune shifts.

Beam-beam Effect on the BTF in Bunched Beams

2014
We present studies on the transverse baseband Beam Transfer Functions (BTFs) in bunched beams at high energies. The goal of the work is to evaluate whether transverse BTFs can be used to diagnose the tune spread arising from transverse nonlinearities such as the beam-beam effect and space charge.

Beam-beam simulation with non-Gaussian beams

AIP Conference Proceedings, 1990
A new method of calculating the beam‐beam force for High Energy Colliding Beam Machines is given and the method does not assume that the particle distribution is gaussian. With the method, the coherent beam‐beam tune shift as a function of beam current is reproduced for the horizontal case. (AIP)
