Injector De-cabling Project Enlarged meeting # E. HARROUCH, EN-MEF, on behalf of the Injector De-cabling Project Team

Content Status by machine Follow-up on Booster Decision making on partial/full removal in Booster YETS organization Conclusions

Status by machine Machine/areaTotal number of signal and control cables (Excluding DC and not known cables) Identified obsolete cables (with or without purple tape) Last talk Booster12’0002’694 (23%) 25 % SPS – BA5~ 6’5003’250 (50%) 50 % SPS – BA3~ 8’ % PS – CENTRE RING~7’ (14%) 14 % TT2~3’00072 (2.5%) 2 % Reminder: cables which are in use now and are targeted to be replaced for future projects are not considered today as obsolete cables. They are out of the scope of this project and must be treated by the future project teams.

EN-EL ~500 cables analysés 1-Câbles signaux et contrôles : Cablothèque papier : Emergency stop 96  being investigated by H. de Maynard General 20  being investigated by S. Delarue Câblothèque Gesmar: voir fichier EN-EL attaché  212 cables (TE-EPC) tous en utilisation 2-câbles BT : voir fichier EN-EL_BT Analyse par S. Delarue : 3 câbles obsolètes, le reste en utilisation

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

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

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.

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 ?

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 ) under the responsibility of EN-EL  general lock-out is mandatory.

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

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

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.

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.
