%0 Journal Article %T Circular Modes for Flat Beams in LHC %A A. Burov %J Physics %D 2013 %I arXiv %R 10.1103/PhysRevSTAB.16.061002 %X Typically x/y optical coupling is considered as unwanted and thus suppressed--particular exclusions are electron and ionization coolers. Could some special coupled modes be effectively applied for the LHC complex? Apparently, the answer is positive: use of the circular modes in the injectors with their transformation into planar modes in the LHC allows both the space charge and beam-beam luminosity limitations to be significantly reduced, if not practically eliminated. %U http://arxiv.org/abs/1301.7743v1
