The On Line Read Out System for the Radiation Monitoring System in the LHC Accelerator
A.Nyul*, C.Pignard, D.K.Kramer, T.Wijnands (CERN)
Radiation induced damage to electronics in the underground tunnel of the LHC accelerator is a major concern. The LHC radiation monitoring system provides on line measurements of the radiation levels at the location of the electronics and provides an early warning when the levels start to increase. In this paper, a description will be given of software architecture that is used to control the nearly 400 devices in the 27 km long tunnel. The entire system is database driven and particular attention will be given to the operatinal alarms, timing and controls databases. Furthermore, a summary of the first operational experience since 2005 will be given. Finally a new data visulisation tool will be described.
