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

– Factory Acceptance Test (Cegelec Marseille) May 05

– Site acceptance of the pilot installation “LHC 0” - June 2005

– Organisation of the LHC 8 installation – October 2005

– Organisation of the LHC tunnel doors/grids installation• Done by TS/IC

LHC Access Safety SystemGoals:

– 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).

– Distributed, highly reliable interlock system • Strictly designed according to the prescription of the IEC 61508 • To be demonstrated to the French Nuclear Authority INB

Status:– HW and SW Architecture prototyping (Siemens Safety Matrix).– Good progress on the :

• Project documentation• Cabling • Safety studies.

– Identification of the LHC machine elements that will be interlocked is completed

– Tender for the system realisation, installation and commissioning.

Open issue/Challenges

• Experiments– Further investigation required

• Pilot installation:– Integration of the numerous technologies involved– Validation of the system by the users

• Safety validation of the global architecture– To ensure that the safety requirements (INB) are met

• Finish the integration (1,2,3,4,5,6) and organise the installation

• Cabling – Strategy and LHC point 8 are OK, – Specify the cabling architecture for the remaining LHC points

• Review and Optimise the full CERN Access « process » – Training, authorizations

17

Conclusion

• Architecture of the LHC Access System is now designed, and is checked to verify that it meets the safety requirements of the LHC operation and the IEC 61508.

• A pilot installation will be tested in the summer 2005 to validate the concept with the users as well as the integration and performance of the numerous sub-systems.

• The specification of the LHC Access Safety side is completed, the hardware and software architecture has been studied, progressing on the prototype.

• A call for tender has been launched to cope with the LASS programming and installation.

• The identification of the machine elements that will be interlocked is completed.

• Despite the difficulty encountered for the system specification, for the time being:– In line with LHC planning
