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.
