Towards An Optimization of the LHC Intersection Region Using New Magnet Technology

A strategy for optimizing the intersection region of LHC is presented. The quadrupole triplet is moved closer to the intersection point, within the footprint of the detec tors. The 350 T/m inner quadrupole is designed using a structured cable that incorporates internal refrigeration with supercritical helium. The separation dipole utilizes a levitated-pole design. This approach opens the possibility to achieve a minimum β without increase of the chromatic and geometric aberrations. The crossing angle can be reduced, and the aperture required in the quadrupole triplet is reduced sig nificantly. The additional space that is opened in the lat tice can be used for additional quads to improve the inser tion matching.
