LHC days 2003

The LHC days 2003, held in Les Diablerets from 2nd to 4th June 2003 and attended by more than 130 participants from 6 divisions of CERN, bear witness of the broad involvement of CERN in the LHC, and of the development of the project in its construction and installation phases. The core responsibilities of the Accelerator Technology division, such as superconducting magnets, cryogenics and vacuum, took a large share of the program, but the related topics of machine installation, commissioning, testing and operation, as well as the interface with the experimental areas and their physics detectors provided the occasion of dynamic exchanges and intense discussions, as they constitute the forthcoming phases of our work on the project. This report summarizes the presentations and discussions which took place during these three days.
