Title :
Perturbation of the periodic dispersion under beam crossing optics in LHC
Abstract :
Beam crossing and separation schemes in the LCD interaction regions impose non-zero closed orbit in the low-β triplets. The related perturbative dispersion is derived; propagation, multi-crossing interference, perturbative effects around the ring are investigated and quantified. Horizontal and vertical compensation schemes are presented
