They are out of the scope of this project and must be treated by the future project teams.

4. EN-EL ~500 cables analysés 1-Câbles signaux et contrôles : Cablothèque papier : 112.501112.700Emergency stop 96  being investigated by H. de Maynard https://edms.cern.ch/file/1220061/1/112501-112700.pdfhttps://edms.cern.ch/file/1220061/1/112501-112700.pdf 112.801113.000General 20  being investigated by S.

Delarue : 3 câbles obsolètes, le reste en utilisation

5. BE-BI La DEC BI comporte maintenant 349 câbles Pour ce qui est des câbles utilisés, je n’ai pas de liste de Franck Guy Guillot-Vignot, Jocelyn Tan, Jeroen Belleman, Marek Gasior, Franco Lenardon, qui sont tous responsables de racks au Booster. Le point positif c’est que actuellement j’ai les listes de câbles utilisés de 5 personnes sur 10

6. TE-VSC DEC completed, will not evolve Used cable list under investigation. Some TE-VSC cables are not listed in EN-EL database

7. EN-STI DEC with 7 cables. Gesmar list analysed : green = EN-STI and in use, yellow = other group (50 cables). Paper list : analysis in progress.

8. TE-ABT 553 cables were announced obsolete but only 222 are really obsolete, the remaining is still in use till LS2 (Current BI.DIS) A DEC must be edited with these 222 cables The case of the former BI.DIS is not yet defined: can we consider it as an obsolete system ?

13. YETS organization Lock-out of all services during identification and cable disconnection  in conflict with some systems  Identification and cable disconnection (YETS 2015) under the responsibility of the equipment group  Up to the equipment group to decide for the lock-out of its equipment  Working teams will need the adequate electrical accreditation  Removal of the obsolete cables (EYETS 2016- 2017) under the responsibility of EN-EL  general lock-out is mandatory.

14. YETS organization Re-commissioning after disconnection/removal – Common procedure  a dedicated sub-WG will be launched soon. Will address the following topics: Procedure for already disconnected cable Procedure for not yet disconnected cable Procedure for orphan cable List of tests to be achieved after disconnection

15. YETS organization YETS 2015/2016 Booster = 9 weeks available / SPS = 7 weeks available : Circuit lockout Cable identification Cable disconnection System tests

16. YETS organization Current proposal: Circuit lockout: 1-2 days Cable identification and disconnection for separate systems. 2 weeks in 2 shifts Check of separate systems: 2 weeks in 2 shifts Cable identification and disconnection for communication system: 2 weeks in 2 shifts Check communication system : 1 week in 2 shifts Co-activities during YETS and EYETS > Schedule to be prepared Tight schedule for BA3 & BA5 Operators might help.

18. Conclusions Booster: an exhaustive approach is followed. Each listed cable is being analyzed by group owner/user (  Obsolete cables + Used cables). Almost complete! Results: Paper listings contain more obsolete cables than Gesmar A lot of cables seems already removed, although they are still listed in DB. Used/unused ratio varies very much, depending on the equipment groups considered Only 25 % obsolete cables were identified up to now, this result will not evolve any longer and should be considered as final. The same methodology will be applied on SPS and PS.
