Summary of the Workshop on Beam-Beam effects in Large Hadron Colliders (LHC99)

The beam-beam interaction can limit the performance of hadron colliders such as the LHC and has to be taken into account during the design of the accelerator. A workshop was held at CERN from 12 to 16 April 1999 to review the current knowledge and experience and to discuss ongoing and future studies. The contributions and details of the discussion and the summaries are compiled in the proceedings of the workshop [1]. While these proceedings are a working document for further studies, this report intends to give an overview of the main problems and provides the interested but non-specialised reader with a survey of the critical issues, together with the proposed solutions and studies.
