Abstract :
One of the straightforward ways towards the higher luminosity in the LHC is a replacement of the present 70 mm NbTi quadrupoles with Nb3Sn quadrupoles which would provide the same field gradient but in a larger aperture. Conceptual designs of such magnets with 90 mm aperture have been developed and studied. This paper discusses the possibilities and limitations of further increasing the aperture of Nb3Sn low-beta quadrupoles, and shows that an aperture up to 110 mm is possible.
