09:30 → 10:30 Machine Interlocks Status (B. Puccio)

The Machine Interlocks systems are good examples of vertical slices in Controls. The monitoring part is exclusively using the AB/CO software solutions. This integration of these safety systems has been successfully performed in close collaboration with the different sections of AB/CO. The presentation will show the current status of the five (*) Interlocks projects managed by the CO/MI section. For each one of these projects the operational status will be described briefly . In addition, concerning the CO solutions, a status of “what has already been done” and “what remains to be done” will be shown. (*) Beam Interlock system, Powering Interlock system, Warm magnet Interlock system, Fast Magnet current change monitors & Safe Machine Parameters system.

10:30 → 10:50 LHC Post Mortem Status (M. Zerlauth)

The causes of emergency beam aborts in the LHC or in the worst case equipment damage have to be revealed to improve operational procedures and its related protection systems. The correct functioning of the various equipment and protection systems with their required redundancy has to be verified after each such event. Therefore the main questions to be answered by the LHC Post Mortem system are the following 1. What happened? a. Initiating event b. Event sequence leading to dump/incident 2. Did the various equipment and protection systems perform as expected? The presentation will give an update on the current status and ongoing developments around the analysis framework as well as the various analysis modules (as proposed in a TC early this year). Depending on the available time a small demonstration could conclude the presentation.
