Long-Range And Head-On Beam-Beam Compensation Studies in RHIC With Lessons for the LHC

PDF Version Also Available for Download.

Description

Long-range as well as head-on beam-beam effects are expected to limit the LHC performance with design parameters. They are are also important consideration for the LHC upgrades. To mitigate long-range effects, current carrying wires parallel to the beam were proposed. Two such wires are installed in RHIC where they allow studying the effect of strong long-range beam-beam effects, as well as the compensation of a single long-range interaction. The tests provide benchmark data for simulations and analytical treatments. Electron lenses were proposed for both RHIC and the LHC to reduce the head-on beam-beam effect. We present the experimental long-range beam-beam ... continued below

We present the experimental long-range beam-beam program at RHIC and report on head-on compensations studies based on simulations.
