Tue 10.04. - LHC Machine For the LHC to provide particle physics with proton-proton collisions at the centre of mass energy of 14 TeV with a luminosity of 1034 cm-2s-1, the machine will operate with high-field dipole magnets using NbTi superconductors cooled to below the lambda point of helium. In order to reach design performance, the LHC requires both, the use of existing technologies pushed to the limits as well as the application of novel technologies. The construction of the equipment followed a decade of intensive R&D and technical validation of major collider sub-systems. Installation is on the way, with nearly all magnets installed in the former LEP tunnel. Sectorisation of the accelerator allows commissioning the highly complex hardware in parts of the machine in parallel to installation activities in other parts. The lectures will focus on the required LHC performance, and on the implications on machine design and technologies. The superconducting magnets to deflect and focus the beams together with the powering system supplying about 7000 magnets connected in 1700 electrical circuits with a total current of more than 2 MA will be discussed. The systems to ensure safe operation of the machine in the presence of an unprecedented quantity of energy stored in both magnets and beams will be presented. The lectures will conclude by describing the ongoing activities and an outlook to the future. Rüdiger Schmidt
