Abstract
Prior to their final preparation before installation in the tunnel, the ∼1800 series superconducting magnets of the Large Hadron Collider (LHC) machine will be entirely tested at reception on modular test facilities using dedicated control systems. Teams of high-skilled and trained operators operate the test facilities. Significant improvements have been implemented in the control & SCADA systems. This chapter describes the typical test sequence and how CERN has organized and is running the concurrent operation of 12 cryogenic test benches, with the help of the control and supervision systems. The present production of the test plant demonstrates that a messaging system embedded in a web-based follow-up system can help the coordination of 3 teams from different area of expertise. More experience is still needed for outputting meaningful statistics and to identify hidden bottlenecks in the test production flow. For that purpose additional analysis work has do be done on the recorded data.
