The PS Complex
EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
17 interlinked zones
Very compact and complex zoning as the PS Complex was extended and changed over many years
Integration of equipment in small access areas will not always be easy

The redundancy, in case of failure of one EIS-F, will be propagated one zone upstream of the zone where access takes place
In total up to three EIS-F can protect a zone

IEFC Workshop, March 2011

8. Access Control Responsibility
The PS Complex operations team:
Puts zones in safe for access state (trip of a zone)
Distributes keys (authorization done by system)
Unlocks remotely the access door
Matches the number person entering with number of keys taken
EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
Ensures that only persons enter that were authorized
Large responsibility with OP teams
No authentication
Simple access points

10. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
Future PS System
The future system is based on the main principles of the LHC system:
Comply with “Tripartite” agreement (ASN, IRSN, OFSP,..)
Use of airlock system to obtain unity passage
Biometry (iris) to obtain authentication
Less responsibility with OP teams and more automation
Well defined system modes
However,
A small material access will be added (back pack, toolbox, oscilloscope, etc.)
The access process will be optimized
The lessons learn shall be taken into account

11. Personnel Access Device
The LHC PAD is fully motorized
A simplified PAD is being considered, but no compromises on safety
EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
The more complex it is the higher the risk of break-down
A more manual version will require clear signs
The MAD will be the same as used in the LHC

13. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
The system modes
The system will switch between the following modes for each zone separately:
Beam Mode
Transition Mode
Access Mode
Restricted Access
Mode
Closed
General Access
Restricted
Access
Process
Special
Permit
Patrol
No Access -
No Beam
To BEAM
To ACCESS
EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
The modes are only controlled from the CCC using keys and computers
In access mode the key can be removed and stored safely
A test mode is added to safely test EIS-F, using redundancy

14. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
PS Complex Zoning
The zoning of the PS Complex remains in many cases very similar to today’s situation
However,
Some zones will or have been revisited
All safety functions will be rationalized (consequences for equipment groups)
PS Switchyard will be added (inflector zone)
Each zone can be exploited independently, even when another zone is being re-configured

15. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
PS Switchyard
Will become a proper zone with its own access point
No use of magnetic switches close to the machine !
Advantage/disadvantage
PSB can have beam during access in a major part of the PS
No continuity in PS path all the time

18. Complete or Partial Deployment
The aim is to deploy the new PS access and safety system during the 2013/2014 long shutdown (LS1)
Most likely a partial deployment of a large number of complete zones will take place
However, non-renovated and renovated zones shall be fully exploitable
Safety links
CCC console
LHC injector chain has priority
Short shutdown periods for non-LHC related zones are generally longer
In any case good training for the Users and the OP teams will have to be provided

20. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
What about the SPS ?
A working group started end of last year
GS/ASE
BE-OP-SPS (J. Ridewood, J. Axensalva)
Presently an inventory of safety chains and hazards/risks is being made
No clear vision yet (too early)
In order to comply with Tripartite regulation same principles as used in LHC and PS Complex will have to be adopted

21. The Experimental Areas
In the PS experimental areas are autonomous since years
Experimentalists are responsible for access to their zone(s)
PS OP teams has a supervision system using TIM-viewer for support
SPS North Area is being renovated
Until now SPS OP team managed modes and keys
The new system works with same principles as PS experimental areas
SPS OP teams will have a supervision system using TIM-viewer for support (OP development)
The new system has to be operational for start up in May

23. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
Concluding Remarks (1)
The new PS access control and safety system will use same main principles as LHC
Lessons learned will be taken into account
SPS will follow
Many processes and procedures will therefore be homogenized across all accelerators
Unity passage
Authentication using biometric checks
Access using RF-Id on personal dosimeter
Visitor categorization and access
Material access
However, new(er)/other technology will be used

24. EVOLUTION AND FUTURE OF THE ACCESS AND SAFETY CONTROL SYSTEMS
Concluding Remarks (2)
Partial deployment requires careful interfacing with present system
Safety functions and Operability from CCC
Training on the new access and safety system for users and the OP teams is very important for successful exploitation
The access systems for experimental areas are all based on the same functional principle and require less intervention by CCC
More autonomy with experimentalists, but supervision remains available in CCC for support
