31. QPS Activities

Knud Dahlerup-Petersen (CERN)

25/01/2011, 08:30

The long shutdown activities of the Circuit Protection section form integrated parts of the medium- and long term plan for the consolidation and upgrade of LHC detector and extraction equipment which is required for maintaining and adapting the complex and safety-critical QPS systems. Although every coming TS shall be efficiently used to advance with these works, a major part of the tasks,...

32. Kickers and dumps

Volker Mertens (CERN)

25/01/2011, 08:55

Planned major hardware interventions include the completion of the staged dilution kicker system in point 6 (installation of 2 last tanks and associated generators), replacement of the extraction protection elements TCDQ (for performance reasons) and possibly the replacement of 2 injection kickers. The reliability overhaul program for the extraction kicker generators will be completed, and...

30. The LHC RF System: plans for the next long shutdown

Olivier Brunner (CERN)

25/01/2011, 09:20

The potential limitations for future running of the LHC RF systems are presented. In particular the problems of trips, hardware failures and limitations encountered during 2010 operation period are discussed, with emphasize on the possible hardware modifications and upgrades during the next long shutdown. The main technical challenges as well as the consequences of delaying the shutdown from...

29. R2E relocation and shielding activities

Anne-Laure Perrot (Unknown)

25/01/2011, 09:45

In the framework of the R2E mitigation project, relocation and shielding campaigns will be performed during the next long shutdown in parallel in Points 1, 5, 7 and 8. About 15 groups will be involved in these R2E activities with work periods from few days to several months. The baseline for these relocations and shielding installations is today defined. The status of the integration studies...

37. CV

Serge Deleval (CERN)

25/01/2011, 10:30

The presentation gives an overview of the major projects and work foreseen to be performed during the long shutdown on cooling and ventilation plants. Several projects are needed according to the experience of the last years, in particular the modifications in the water cooling circuits presently in overflow. Some other projects are linked to the CV consolidation plan. Finally, most of the...

35. EL Activities during 2012 Long Shutdown

Francois Duval

25/01/2011, 10:55

EN/EL will be leading 3 main LHC projects: - R2E (relocation of EL equipment in LHC points 1, 5, 7 and 8) - Water cooled cables to be replaced in 3 LHC points - UPS (APC SILCON) to be replaced (circa 80 units) EN/EL will be involved in many others. Only a few of them are known today. (Vacuum pump cabling, RF cables replacement, QPS cabling …..) Several non LHC projects but...

36. Access and Alarm Safety Systems - Activities for the 2012/2013 Long Shutdown

Silvia Grau (CERN)

25/01/2011, 11:20

This paper presents the 2012/2013 long shutdown activities for the access, emergency evacuation, gas and fire detection systems. First, an overview of the required minimal annual maintenance and tests is presented, including the first feedback from the 9 weeks of the technical stop. Second, planned upgrades, new installations and consolidation activities, such as the R2E relocations and...

39. What do the experiments have planned?

Austin Ball (CERN)

25/01/2011, 11:45

The shutdown in 2012-13 is the first opportunity since physics operation started for the experiments to conduct comprehensive maintenance. This long shutdown will also be used to consolidate and upgrade the experimental apparatus so as to fully exploit the expected improvements in LHC performance. This talk will summarise the planned activities in all experiments and attempt to identify areas...
