7. LHC2- ALICE

8. ALICE - Access via PX24

9. Functional test of the LHC Access system in point 8.
LACS & LASS overall system tests
complete CCC and CCR hardware & software
Complete LHC8 interlocked area
Test scope:
Access Operation in “General, Restricted, Closed modes
Individual equipment test
Access points, doors, shielding walls, patrol, …
Patrolling of the 13 access sectors (incident simulation)
LHC 8 closure -> safe condition for Beam Operation
Moving to Beam operation:
Trigger of the Beam Imminent Warning
Unlocking of the Emulated LHC EISBeam and of the SPS
Intrusion
Checking of the system behaviour in case of :
emergency stop, equipment, control system, power system failure
Moving back to Access operation
Not included: access control delegation to XCR

10. Synchronised operation from XCR and CCC
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

11. Functional test of the Access system in LHC8.
Results :
First functional tests in LHC8 allowing the verification of all the concepts and equipment.
Tests were globally successful
Safety functions operated as specified
Non conformities concerning installation defects, ergonomics of the restricted mode of operation, and the intercom system.
Clear need of training and users’ information
Test organization
Machine reserved 2 evening and 1 Saturday
Thanks to LHCB for the cooperation,
Test were eased as the cavern was not completely fenced
Next stages: CMS, ATLAS, ALICE testing
To be organized in collaboration with LAAWG

12. Feedback from operation AND open issues
Use of the new access points:
Initial difficulty of use of the new access procedure
As far as we know, everybody has been able to access
Much faster “burn-in” than previous recorded experiences (see PX15).
Much faster and flexible authorisation system (on-line update of databases from registration to access point).
Training of experimental control room operators
Open Issues
Operation of the Non-interlocked areas
Access point in pressurized areas
Being analysed by SC (R. Trant LEAF 10/5/07)

13. Important points concerning the Exp. Areas.
LHCB
Test after final installation of fences and shielding wall
Patrol procedure
Access procedure to the non-interlocked area
PZ85 renovation
ATLAS
SSA: pilot installation in June, available in September
Partial commissioning planned W33-35
PX15 Access Point upgrade
CMS
Installation of the remaining access points (UPX56)
Cabling of the Patrol devices in the cavern
Commissioning planned W30-32
PM54 Access Point Design & Installation
ALICE
W27-W40 installation and commissioning
Work preparation

14. Conclusion
Good progress – despite a hesitant Contractor.
Expect to be ready as planned (Master Schedule)
Operational issues - to be finalized with the experiments.
