Features and implications of different LHC crossing schemes

To avoid unwanted beam-beam interactions, the two LHC beams cross at an angle in all experimental interaction points. The choice of the crossing plane in the different areas has fundamental consequences on the effects of the long range beam-beam interaction. Recent changes to the hardware, i.e. introduction of a beam screen into the triplet quadrupoles, may limit this choice or reduce the flexibility. The consequences of different crossing scenarios are presented in this report. Other implications such as limitations to the correction possibilities and the flexibility of the crossing geometry are addressed.
