  Long-range beam-beam effects are a potential limit to the LHC performance
with the nominal design parameters, and certain upgrade scenarios under
discussion. To mitigate long-range effects, current carrying wires parallel to
the beam were proposed and space is reserved in the LHC for such wires. Two
current carrying wires were installed in RHIC to study the effect of strong
long-range beam-beam effects in a collider, as well as test the compensation of
a single long-range interaction. The experimental data were used to benchmark
simulations. We summarize this work.
