An invitation to design LHC systems for TCR supervision

With the LHC technical infrastructure in place, one of the main concerns is to achieve maximum availability and reliability through, for example, appropriate operation and supervision. This paper is intended to draw the attention of the experts to the shortcomings of the existing remote supervision of the technical infrastructure. These reduce the efficiency of the Technical Control Room (TCR) due to the large number of alarms. There are alarms generated by maintenance or shutdown activities, those connected to disused hardware and others not indicating an intervention or without sufficient documentation. Systems optimized not only for nominal load but also for operation modes such as accelerator shutdown and system maintenance could significantly decrease the number of alarms and thus reduce system downtime and operational costs. Additionally more sophisticated local and remote control systems could improve the supervision and the analysis of Repetitive Alarms.
