  5. LHC Access Control System Goals: • Manage access rights • Identify user • Verify authorization • Automatic or remote access control Status: • Contract running since September 04 • System engineering completed • Site acceptance of the pilot installation “LHC 0” • Started in June 2005 - completed in January 2006 • +3 months: quality and integration issue • LHC 8 installation • Doors/grids installation (TS/IC) • Cabling (TS/EL) • Access equipment Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  10. From a prototype to a reliable system • Management of the various access mode regarding the safety • Control system performance • Video/Audio integration • Material Access Device Robustness • Biometry integration and link with Human Resource Database • Man Machine Interface Design • Patrol • Contractor management : quality, deadlines Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  11. LHC Access Safety System Goals: • Protect personnel during Beam operation • nobody inside - Stop LHC if a door is forced • Allow Access operation when safety conditions are met • No radiation hazards (LHC beam, RF). • Nuclear Safety system • Audited by the French Nuclear Authority INB Status: • HW and SW Architecture prototyping done • Identification of the interlocked LHC machine elements completed • INB documentation completed • Safety studies completed • Contract for the realisation of the system started in October 2005 • SW & HW Design progressing well Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  12. LHC Access Safety System – INB • Architecture reviews with the French Nuclear Safety Authorities – IRSN: June, August, October 2005 • Siemens safety PLCs accepted together with a diversified redundant system • cable loop surveying the external envelope of the machine and acting on the Beam Important Safety Elements • Cable loop design finished (budget – copper prices!) • Integration in the existing architecture • First version of Annex 1 of Report Préliminaire de Sûreté, EDMS: 679353 Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  13. LHC Access Safety System – Remarks • Involvement from AB to be continued: • Lack of official product manager • Fast answers to few remaining issues (patrol, radiation Veto etc.) • Integration of redundant cable loop • Operational procedures: • Operator training • Patrol procedures • Equipment tests • Lessons from the test • As we use Failsafe PLC: all must be perfectly mastered • Otherwise it goes Failsafe • Not easy in absence of specification Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  14. Safety Control Panel (EDMS No 578789) Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097 Louis. Hammouti

  15. Access mode selection (EDMS No 584513) Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097 Louis. Hammouti

  16. Data from LASS - ISE access and safety chains Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097 Louis. Hammouti

  19. Man Machine Interface design • Several iteration were done with AB/OP • Thanks to the collaboration of R. Giachino and G. Roy • To be continued • 60 views defined, plus integration with logging and alarm system, and technical supervision • Version 1 is frozen now • Under realisation • Changes will be done after using ECR • Delicate integration of the Safety and non Safety part • Due to the LASS isolated network Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  20. Safety LASS LACS Integration & Installation INB AIWG LHC Access System Principles (AIWG) Safety Plan Access Safety Specification Access Control Specification LHC Sectorisation & Integration Review Preliminary Risk Analysis Access Safety Architecture Design Access Control Tendering Cabling Definition Safety Function Specification Access Safety Tendering Contract Access Control Design Installation preparation Preliminary Safety Study (Architecture) Contract Access Safety realisation INB Documentation Access Pilot Installation LHC0 Installation Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  21. Conclusions • Progressing step by step • Good benefits from documentation efforts on the INB Side • LHC Access System is a complex system integrating numerous technologies • V1 frozen : this is the “Baseline” • We can always do better -> V2 with an ECR • Challenge: Upgrade it from a functional prototype to a robust system • AB support needed: specification work remains • TS/CSE fully mobilised to make it !

  24. Planning Strategy Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097

  25. Installation • Phase 1: • No impact on magnet transport and installation in the tunnel • To assure safety of personnel, as much as possible avoid the period of short circuit tests in UA / RA • Access works will be in parallel with the activity of interconnection of magnet in the tunnel • Phase 2: • Access surface installation is only allowed to start in each point when HC in adjacent LSS sectors has started (to avoid perturbation of transport of heavy and big material) • Phase 3: • Co-activities not allowed during the first and last 2 weeks of Cold-down HC and the period dedicated to Powering test Authors: P, Ninin, L. Scibile T, Ladzinski EDMS: 698097
