We report the status of the optics design for a local chromatic correction with extremely flat beams at the LHC. Together with a Large Piwinski angle, this optics opens up the possibility of crab-waist collisions at the LHC, for which a new layout of the LHC insertion region (IR) is needed. We present a complete optics, and discuss the parameters of the final “double-half” quadrupole.
