The PS Complex

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 new system will re-used the redundancy that we already have in the present system

•TT2 EIS.1•TT2 EIS.2 TT2 •AD-Target EIS.1

•AD-Target EIS.2

t

• Beam Flow

PS SWY

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

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


Ensures that only persons enter that were authorized

Large responsibility with OP teams

No authentication Simple access pointsEV

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

The more complex it is the higher the risk of break-down

A simplified PAD is being considered, but no compromises on safety

A more manual version will require clear signs The MAD will be the same as used in the

LHC

Optimized Access Process (PAD)

Key release on hold until access finished

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

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

No continuity in PS path all the time

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

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

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

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 IEFC Workshop, 21 - 24 March 2011Rende Steerenberg, BE-OP

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
