LHC progress and status

The LHC is a superconducting collider to be installed in the LEP tunnel for high energy pp, Pb ions and ep collisions. An overall machine optimization, including a new lattice arrangement and an increased dipole aperture (56 mm), will be presented. The increased energy to field ratio is (0.81 TeV/T). Recent results from a magnet model with industrially produced coils assembled at CERN reached 10 T with a limited training and ultimately attained 10.5 T. Demonstrating that operational fields in excess of 9 T can be obtained. Results from previous models and a 10 m-long prototype will be given. In total seven of these prototypes are being constructed by industry. In December 1991, the CERN Council unanimously adopted a resolution stating that the LHC is the right machine for the future of CERN and requesting a final proposal in 1993, which is being actively prepared and is summarized in this report
