The magnets installed in the CERN accelerator complex provide impressively high standards of reliable operation thanks to a tight program of preventive maintenance and consolidation: in total during 2009 the machine down-time due to magnet failures was below 100 hours. However the risk of approaching “end of life” situations, not signaled by observable precursors, increases with time and the...

7. Progress with POPS

POPS is the new power system for the PS main magnets. It will replace the present rotating machine and its associated auxiliaries. A contract with CONVERTEAM (FR) was placed in December 2007 and it was planned to start its commissioning in December 2009. Unfortunately, the shutdown 2009-2010 had to be suppressed to serve LHC. The reception tests with Converteam will be done in January 2010...

9. Critical overview of RF equipment in the LHC injector chain

Erk Jensen

10/02/2010, 15:00

The RF equipment of the LHC injector chain (Linac2, Linac3, PSB, LEIR, PS and SPS) is considered with scrutiny in view of its reliable operation. We analyse present and past failures and weaknesses of the different RF systems and indicate planned, started or implemented remedies. We equally try to anticipate future risks that may jeopardize reliable operation and give strategies for their mitigation.

10. Status and progress of ACCOR

Marc Vanden Eynden

10/02/2010, 16:00

This talk will present the achievements made in 2009 in the context of the Accelerator Control System Renovation Project (ACCOR) for 2009, in particular concerning the integration and validation of new front-end hardware and software technologies and core control system building blocks. The second part of the talk will concentrate on the planning aspects, and on the strategy that will be used...

11. Outstanding work and possible worries with electrical distribution cables

Francois Duval

2009 was for EN/EL a new departure; group was repowered, 15 more people join the group and a consolidation budget of 40 MCHF was allocated to update the distribution network. EL is now able to deal with more than the day to day business; EL is focused on training new people and is working on the design of the 2015/2020 distribution network. In 2009, selectivity has been improved in several...

12. Reliability of the cooling and ventilation installations for the injectors

Serge Deleval

10/02/2010, 17:00

The presentation, after a brief summary of the 2009 run from the CV point of view, will focus on several major improvements and concerns. Such as the optimization of the water treatment that has shown good result during the last years. The present status of the control system for the PS and SPS cooling stations and the plan for the future modification will be presented. Several other...
