LHC Access System
LHC Access System
• LHC Access Control System – LACS
– Supports the physical equipment regulating the access to
the accelerator
– Allows operation of access equipment
• LHC Access Safety System – LASS
– Provides interlock between EIS-faisceau and EIS-acces
– Ensures the collective protection of personnel from the
radiation hazards

Access points - Underground
• Installation of the access points in UX85, UJ83
and UJ87 in progress
• Complete test of the access point UX85,
including the IHM and control from the CCC,
supervision and maintenance procedures
-> mid September
• Circulation of personnel not affected

Installation Strategy – Underground Access Points
•
•
Not used for personnel passage before the definite closure of the area
(installation of the grids)
Configured for biometric recognition and RFID badge identification

Access for the Pits Head
•
Prerequisites:
•
Constraints: minimize the impact on the personnel flow during the LHC
installation period
•
Strategy:
–
–
–
Access points UX85, UJ83 and UJ87 integrated and validated
Access Help Desk manned and operational
User information:
• Posters, group secretariats, TCC, bulletin
–
Biometric recognition disabled
–
Use of the new CERN site access cards (equipped with MIFARE RFID chips) for the personal
identification – Under validation
• Current CERN site ACCESS magnetic cards is being progressively replaced by the new
RF cards (TS/CSE responsibility)
–
–
Dosimeters not required during the LHC installation
Before LHC start-up, users shall be requested to get a dosimeter equipped with the RFID
chips
August 2006
LHC Access System
• New CERN Site Access Cards:
August 2006
LHC Access System
•
Persons working on the Points 7 and 8 will be asked to
retrieve the new access cards at the Building 55 already in
September
•
Access to the LHC interlocked areas in the LHC operation
phase: personnel dosimeter equipped with the RFID chip and
biometric identification
August 2006
LHC Access System
• Short term objectives Points 7 and 8:
– PM85:
• Dismantling of the existing system: beginning October (1
week)
• Installation and integration of the new system (1 week)
• Presence of the security guardian required during
dismantling and installation
• Operational mid October
– PM76 operational end October
– PZ85 operational beginning November

P8, P7, P4 -> 2006
P1: January 2007
P5: February 2007
P3: March 2007
P6: April 2007
P2: May 2006
Final installation (inter-site doors, biometric identification, dosimeters with RFIDs, grids)
June 2007
• Site functional tests per site at the end of the site installation; in coordination with
machine groups concerned
• Global and Final tests
– at the end of the installation during summer 2007
– special requirements (coordination with different groups concerned, access
restricted to personnel involved in tests)

LHC Access System
Tests
• Tests strategy defined all along the I&C phases till
transfer to Operation and Maintenance
– EMDS 497865
– HW, SW Functional and Safety (INB requirements !)
• Tests Phases:
•
•
•
•
•
•
Local acceptance
Integration
Functional Site
Functional Inter-site
Global Tests and Final Tests
AB/DSO INB Tests
• Roles and Responsibilities being defined with different
groups concerned
– project team, contractors, HC, equipment groups, experiments, AB

LASS General Status
• Safety software under development
• Functional software (Man machine interfaces..)
under development
• Electrical design: power supplies, rack installation
drawings, LASS command interface (Pupitre), cable
loop – delays, but progressing well recently
• Goal: follow-up with the installation the pace of the
LACS installation in order to synchronize the testing

Conclusions
• Objectives:
– LASS and LACS operational in LHC7, LHC8, CCC by mid November
2006
• All pieces of the ‘LEGO’ are there or under production
• Planning relies on:
– No major technical issues during integration
– Contractors and subcontractors respect the deadlines
