Injector De-cabling Project Coordination Meeting for the PSB and PS & TT2 Facilities YETS 2015-2016 01.10.2015 S. EVRARD, EN-MEF, on behalf of the Injector De-cabling Project Team

Contents Scope of the project Status by machine YETS activities @ Booster Identified issues Project Information Sharing

Scope of the Project To identify and remove obsolete cables within the injector complex, until end of LS2. First  priority:  Identification of obsolete cables in the  Booster and SPS BA5  Partial / total removal must be decided by end September 15’ Triggered by LIU needs (room in cable containment) Second priority: SPS (BA3) Third  priority:  Identification of obsolete cables in the PS, TT2, LINACs   RUN 2015 YETS 2015-2016 RUN 2016 EYETS 2016-2017 RUN 2017 YETS 2017-2018 RUN 2018 LS2 BOOSTER Cable identification IDENTIFICATION Cable labelling LABELLING Cable disconnection DISCONNECTION Cable removal REMOVAL SPS BA5 LEFT REMOVAL BA5 LEFT REMOVAL BA5 RIGHT & BA3 REMOVAL PS, TT2 & Linacs TO BE DEFINED

Status by machine BOOSTER: Machine/area Total number of signal and control cables Identified obsolete cables on Sept. 21st Booster 12’000 3’000 (25%) SPS – BA5 ~ 6’500 3’250 (50%) SPS – BA3 ~ 8’000 PS – CENTRE RING ~7’000 963 (14%) TT2 ~3’000 72 (2.5%) BOOSTER: 3000 obsolete cables to be removed (consolidation budget) before LS2 2800 used cables to be removed and replaced during LS2 for LIU (LIU budget) 2 big cable campaigns for EN-EL (EYETS16-17 + YETS17-18 / LS2) Strong commitment from all the equipment groups during identification and disconnection stages  resources to be secured for YETS15-16

YETS activities @ Booster YETS 2015/2016 = 7-8 weeks to complete: Circuit lockout Cable identification Cable disconnection System tests Current proposal: Circuit lockout: 1-2 days (depending on equipment group decision) 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 : 1-2 week in 2 shifts Schedule being prepared Operators might help.

YETS activities @ Booster Access 6.00 am to 22.00 pm Booster Mon 07/12/15 Fri 19/02/16 @ 12.00 PS Wed 16/12/15 Fri 12/02/16 @ 12.00 TT2 Tue 15/12/15 Access Control transfer CCC  CSA Mon 04/01/16 @ 06.00 Fri 12/02/16 @ 06.00 Draft Planning YETS 2015-2016: PS&TT2 EDMS 1510007 PSB soon Simon Mataguez EDMS 1549666

Identified issues: re-commissioning Re-commissioning after disconnection/removal – Common procedure  a dedicated sub-WG has been launched Will address the following topics: List of tests to be achieved after disconnection Procedure for already disconnected cable Procedure for not yet disconnected cable Procedure for orphan cable

Identified issues: Lock-out 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 Removal of the obsolete cables (EYETS 2016-2017) under the responsibility of EN-EL  general lock-out is mandatory.
