Database Requirements for the Vacuum Systems of LHC

The new Large Hadron Collider (LHC) which will be built over the next decade at CERN requires two independent vacuum systems. On one hand, there will be a high vacuum in the two 26 km long beam pipes, on the other hand there is need for insulation vacuum in the cryostat and helium distribution system for the super conducting magnets. Several thousands of components will have to be acquired, assembled and installed in the ring tunnel. All active components will eventually have to be remotely controlled. Several phases can be identified during the project lifetime, starting from the preliminary design and ending with exploitation. Each phase requires different sets of data to be available. This paper identifies the required data, when this data should be available, the needs for integration with other equipment or project databases and the tools which are felt necessary to process the data.
