21. Major events in the technical infrastructure in 2008

Peter Sollander

3/5/09, 2:00 PM

In 2008, the TI operators recorded 38 major events not related to LHC. These events primarily concern the injector complex. This talk will cover the different types of events occurring, study the recurring ones and show what actions have been taken after the events. It will also briefly describe how major events are dealt with in the TS Operations Committee and show what tools are available to...

22. Electrical network: Compensators

Karsten Kahle

3/5/09, 2:30 PM

This presentation outlines the current status of the Static Var Compensators at CERN. It explains the transfer of the SVC's from EN‐EL to TE‐EPC beginning of 2009, and the mode of operation in 2009. An overview is given on the results of the 2008 consolidation programme, as well as a summary of annual maintenance activities in shut‐down 2008/2009. The presentation terminates with an outlook on...

36. Electrical network: 18 KV Network Review and status of the SPS consolidation

Davide Bozzini

3/5/09, 2:45 PM

After a short introduction we will look at the status of the 18 kV cables networks, report case by case the source and nature of the problems encountered in 2008 and explain the corrective and preventive actions taken. The status of the SPS consolidation plan of the 18 kV network will be reviewed. The activities scheduled for the period 2009-2010 to continue with the consolidation will be...

23. Review of irradiated cables in the SPS

Daniel Ricci, Jean-Claude Guillaume

3/5/09, 3:00 PM

The SPS accelerator complex includes roughly 127000 electric power and control cables. The selection criteria for cables are stated in the CERN-IS23 safety instructions that require retention of the cable functional capabilities up to an integrated radiation dose of 0.5 MGy for general-purpose cables and 10 MGy for special radiation resistant cables. In some SPS areas the cumulated dose over...

24. Consolidation of access system for the injector complex

Pierre Ninin

3/5/09, 4:00 PM

In 2008 The ASE group started a project for the renovation of the PS Access system, this concerns the safety interlocks as well as the access control functionalities. In collaboration with BE/OP, the specification of the new system is progressing, covering aspects such as preliminary risk analysis, definition of the safety functions, access sectorisation, definition of the Important Machine...

25. Consolidation of buildings and tunnels related to the injector complex

Cristiana Colloca

3/5/09, 4:30 PM

The presentation gives a general overview on the consolidation needs on civil engineering infrastructure (surface and underground) related to LHC Injectors. The actions to be taken in the future are evaluated following priorities related to safety or to operational accelerator needs.

26. Cooling & ventilation

Guillermo Peon

3/5/09, 5:00 PM

In order to increase reliability of CV systems in the non-LHC accelerator complexes, to reduce down time and to satisfy CV users, the group CV carried out works involving creation and modification of cooling, ventilation and control systems. The presentation describes the most outstanding singular works performed by CV in 2008 that are threefold; revamping of installation through significant...
