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

LHC Access System

LHC Access Control

• 34 Access Points• 95 controlled sector doors• 65 interlocked end-of-zone doors• 26 interlocked ‘portes crionolines + ventilation’• 17 interlocked movable shielding walls• 200 junction boxes• 170 racks• 110 surveillance cameras• 200 controllers (PLCs, PCs)• Control system from CCC and experiments• Supervision system

LHC Access System

Installation Status: sector doors and junction boxes

• Sector doors:– Point 8: 90%– Point 7: 90%– Point 1: 75%

• Junction Boxes:– Point 8: 100%– Point 7: 100%– Point 1: 100%– Point 6: 90%

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

LHC Access System

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:– Access points UX85, UJ83 and UJ87 integrated and validated– Access Help Desk manned and operational– User information:

• Posters, group secretariats, TCC, bulletin

• Constraints: minimize the impact on the personnel flow during the LHC installation period

• Strategy:

– 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

Global Planning

• Installation and Commissioning detail planning– Integrated within the LHC IC General plan (TS/IC)

• EDMS 769853 – Machine and Experiments

• Deployment: – 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

• Tests:• 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)

• Follow-up with MTF

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

LHC Access System

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

LHC Access System

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
