From card to dosimeter - the plan is:

• During LHC Installation- New LHC Access control system gradually operational in pit access points (and elsewhere)

• Operational in PM85, PM76, PM45

- Renewal of the Access points of the non-interlocked areas will be done after LHC start-up

• Minimized perturbation for users- Renew their access card (Bat 55)- No Biometry

• Assistance provided by the CSA & CCC

• For LHC Operation- Biometry enrolment will start in June 07- Access badge integrated into the dosimeter- Delivered in Bat55

LHC Access Control System

Goals:

• Control access to the LHC installation (INB)

• Manage users’ access rights

• Identify user

• Verify authorization

• Automatic or remote access control

Status:- LHC4 :

• PM45 access point under test, UJ43 & UJ47 installation completed- LHC5: Preparation of the installation- LHC 8: installation completed and local acceptance test started


LHC ACCESS SYSTEM

LHC Access as seen by the Experiments

• Local Experiment Room Access Console- Allows the experiment to operate their access points in

only in Restricted Access mode, after delegation by the CCC

- Remote supervision includes audio and video

• Software interface is available to get information from the Access system about User entry/exit and Operational states.

Delegation

• Synchronised operation from XCR and CCC

• Only the Access requests are re-routed to XCR (No control of any Machine related element).

• Audio & Video control

• Delegation cancelled by a LASS VETO or by the CCC

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- Audits by the French Nuclear Authority INB

Status:- Successful Factory acceptance of the CCR and LHC8 racks - LHC4 – LHC5 rack design and fabrication started- Ongoing Cabling verification in LHC5- Installation of the LHC8 racks completed and on going in CCR

LHC8 - LHCb

• Installation completed

• Patrol definition done

• LHC8 Functional tests starting mid-February

• LACS console in XCR – June 07

LHC5 - CMS

• Access safety aspects managed by the LASS- Safety of the underground UX area (sector 12)

• Any entry into this zone SHALL be detected by the system. No unmonitored “holes” may exist…

• Patrol definition done

• Installation: 18/02- 15/04- Constraints ?

• LHC5 functional testing 15/04 – 27 April

• LACS console in XCR – June 07

• Sectorisation completed

LHC1-ATLAS

• Access safety aspects managed by the LASS and the SSA for the Patrol aspects. ATLAS detector is patrolled by ATLAS.- Cfr Elena’s slideshow

• Installation: 26/02- 27/04- Constraints ?

• LHC1 functional testing 15/04 – 27 April• LACS console in XCR – June 07• Most of grids in place, TE 14 & 16 will be relocate• Installation of UPX16 & ULX15 could start end of

February- To be coordinated between us and you!

Conclusion

• Good progress – despite a hesitant Contractor.

• Expect to be ready as planned (Master Schedule)

• Co-ordination with the Experiments: we need a better definition of linkmen for different aspects. Presently we are sometimes grasping for the right person…(wastes our and your time).

• Operational issues - only discussions with the Machine. Any Experimental point of view?
