What TCR operation needs from a monitoring system?

The Technical infrastructure (electricity, cooling, etc.) is expected to have a more serious impact on the operation of the LHC than that of the SPS and LEP. For the prevention of major breakdowns and for an efficient recovery afterwards, it is mandatory to define the activities and responsibilities of the different actors contributing to the overall accelerator system operation. Additionally, a method common to all actors to monitor the status of the equipment needed for a given mode of accelerator operation is essential to improve the overall co-ordination and efficiency. This method covers the analysis, documentation and presentation of systems and system interactions and has successfully been applied to the SPS. The implications and the recommendations for its implementation in the TCR with respect to the existing accelerators or experimental areas and in particular for the LHC are discussed.
