Status with crucial LSS5 kicker transmission line cables Etienne CARLIER LIU-SPS Meeting 8-02-2017

- The cable length from the yellow door ECX5-LSS5 ( ) to the platform ( ) is 61m. - Cable end points in LSS5 (magnet) and ECA5 (generator) defined

Kicker transmission line cables   MKDV1 MKDV2 MKDV3 MKDH1 MKDH2 MKDH3 Cable type CLP50 4x7.0L/10.4 Diameter [mm] 31.5 48 Bending radius [m] 0.6 0.75 Weight [kg/m] 1.25 2.5 Physical length [m] 124.7 119.3 118.7 114.8 115.1 115.5 Normalised length [m] 130.0 120.0 Number of cables 78 15 Total length [m] 10140 1800 Cost per meter [EUR] 45 75 Total cost [EUR] 456300 135000

Purchase status 4x7.0L/10.4 (MKDH) – 150 kCHF CPL50 (MKDV) – 485 kCHF We hope to go for single source, replacement of existing cables. Delivery in 2017 still feasible CPL50 (MKDV) – 485 kCHF Market survey in preparation (> 200 kCHF) Delivery 2017 questionable* MKP LSS1 cable replacement as an option. FC required once option activated (before LS2) Draka was at CERN yesterday and confirmed that they have the capacity to produce the full quantity (10 km) in 3 / 4 months. Order to be placed before 07/2017 at the latest for delivery in 12/2017 * The ? is at CERN with purchase procedure (Spec committee + MS + IT).

Transmission line routing Critical area for integration Transmission line routing

Integration Transmission routing via the upper ECX5-ECA5 level as preferred option Routing via the ECX5-ECA5 ground floor level not possible due to cable bending radius and reduced space available at the level of the elevator Detailed integration study ongoing Scan ECX5-ECA5 gallery done Physical closure of ECX5-ECA5 windows after transmission line installation (closure must be air tight for protection of the shaft against smoke in case of fire)  Under discussion with SPS Fire safety project & HSE Access to the technical shaft from Level 0 via existing crinoline after closure of the 2 windows (Technical shaft is not an evacuation path)  Under study with HSE Removal of sector doors YDPS01.556=PT55 & and doors YDPS01.516=PT51  New SPS sectorisation under study (SPS Access System Project) Cable ladders integration and cable routing Under study by EN-EL

Kicker platform in ECA5

EYETS17-18 - Strategy Install kicker platform in ECA5 Cable start / additional cable length will be stored under the platform Install cable ladders from kicker platform in ECA5 up to magnet location in LSS5 Work over Christmas CERN probably required if cable available in order to be ready beginning of 2018 to start cable pulling If cable available: start pulling cable from ECA5 to LSS5 Cable pulling campaign duration ~8 weeks (2 shifts) MKDV transmission line must normally be installed first. Transmission lines will be installed on the top of the tunnel and first magnet is a MKDV (before QD.51710 ). Connectors mounting (both sides) to be scheduled during LS2 (2 x 8 weeks) If cable not available: start cable routing at the beginning of LS2 during LSS5+ de-cabling campaign (MKDV)
