Compensation of space charge effect at beam-beam interactions in proton-proton colliders

摘要

The compensation of the beam-beam effect by collisions of the circulating proton beam with a space charge of a low energy electron beam has been studied by computer simulation for the LHC collider. A solenoidal magnetic field was considered to keep the electron beam distribution during these collisions. It was shown that for reasonable tolerances of the electron beam parameters quite good beam-beam effect compensation can be obtained and beam-beam tune spread can be reduced by a factor up to about 100. 5 refs., 12 figs.
