MPE Stand-By mandate:

1. Mission:

– To put back in service, as rapid as possible, a faulty installation within the framework (QPS, Energy Extraction Systems and electrical components of the DFBs) during LHC run.

2. Actions:

– Intervene after a call from the Control Centre CERN (CCC),

– Diagnostics and if possible solve the problem remotely

– Organize the intervention with the operator/EIC CCC (RP)

– If needed ask the “Expert” (if reachable) for support

– Archive the intervention in the Logbook (QPS Logbook).

3. Responsibility:

– He must assure his own security as well as those he asked helping him and assure the correct way of intervening in the tunnel

– The technician is responsible for the intervention. If he cannot find a solution he must inform the group hierarchy.

MPE Expert mandate (1/2)

The Expert (based on best effort) :

1. Mission:

– Support the first line intervention in case of complex problems

2. Actions:

– If judged intervene to help the Stand-By technician

– Ask another Stand-By team member to join for intervention

3. Indirectly related actions:

Decrease LHC machine down-time where possible

– Implement solutions for problems

Firmware upgrades

Preventive maintenance

DQHDS main switch exchange campaign

MPE Expert mandate (2/2)

3. Indirectly related actions (cont.):

– Not to be underestimated in hours and workload

– Example:

Arkadiusz Gorzawski developed an interface

logging database – 600A EE signals

- permits preventive maintenance on breakers with too many closing failures

- Currently extended with intervention history per system

Direct result = no breaker exchange so far this year

HUGE EFFORT not visible in Stand-By statistics

MPE Stand-By organization:

Documentation:

– Each equipment specialist prepared a documentation on how to solve a typical problem.

– An updated copy is always available in two Stand-By cars

Regular meeting and training:

– Weekly meeting on Monday morning to transmit the “Piquet role” and share experience over the past week.

– Training are organized in order to be as multidisciplinary as possible.

– Two Stand-By cars available, equipped with tooling, docs and spare parts.

– Storage place in Build.30, 281 and 936 (in front of CCC) Yearly planning:

On our repository, we have a yearly planning with foreseen vacations, official holidays, night and day “Stand-By” turn-over.

– Day calls: transparent to CCC (same number 16.8801), assures intervention during normal hours. This allow night piquet to recover.

– Night calls: outside normal hours and w-e, official holidays included.

SEU – increasing number

17 treated by Stand-by team so far this year

– Symptoms: QPS_OK lost (fill can be continued until beam dump)

• continuous sending PM files or loss of communication

– Action:

• locally power cycle the crate – (and depending on time of intervention)

• Update locally the firmware or– change board for one with new firmware)

– Specialists actions: upgrade of firmware

DQHDS main switch

18 cases treated by Stand-by team so far

– 26 treated in 2010 – we are NOT better in number but much better in time of intervention; almost always IN THE SHADOW causing no downtime to LHC operation

1650 (26%) out of 6200 have been replaced

– All DQHDS of all MQs done and regular campaigns on-going

• Software interlock adapted to MB. One out of four DQHDS of a MB can be down. No immediate intervention needed.

• Why not better in numbers? …

» plastic is getting too hard?? We should hurry up

No faults in the new switches

« IN THE SHADOW »

30 out of 87 interventions “IN THE SHADOW”

• less downtime for LHC operations

Mainly because

– of upgraded Interlocking software in case of a MB DQHDS failure.

– SEU can finish the fill before power cycling the crate

– Preventive maintenance

– Coordination between Equipment Responsible and Machine Coordination in case of longer downtime

Outlook:

Improvement ongoing:

– TUNNEL INTERVENTIONS

• Upgrades on iQPS firmware on SEU

• Switches DQHDS replacement – 1600 done + 500 4-9 July

– Software tools on QPS

• Remote restart – done

• Upgrade Firmware of new Busbar detector 4-9 July

• Interlocks regarding DQHDS – interventions “in-the-shadow”

Potential bottlenecks:

– More radiation to equipment SUE

– Resources are limited, both experts and technicians

– MP3 Stand-By canceled in 201x? Who takes over?

– Back-up for Stand-By team based on best effort

Conclusion :

Conclusion so far as in 2010

– Very efficient: < 2 hours/intervention on site, including access time !!

– High reliability of the systems

– No accident !

Stand-By service interventions seems to be decrease in numbers of hours

BUT..

A lot of work behind the scenes to get there
