EN-STI activities in LHC during EYETS 2016-2017 edms 1714656 Sven De Man + Inigo Lamas Garcia

Activities in LHC and TI Pt 7/Pt 5 Collimator + Goniometer Installation. Assets available from 15/02 Commissioning collimators end of EYETS Main dump consolidations beginning 2017 – as soon as radiation level is stable (ALARA) Replacing TIM Replacement RadMon v.5 by v.6 Installation LSS7 No actions on TDI

EYETS 2016-2017 Collimation Point 5: new “compensation wire” collimators Slot TCTPH.4R5.B2 -> TCTP to be replaced by TCTW#1 Slot TCL.4L5.B2 -> TCL to be replaced by TCTW#2 Point 7: Slot TCSM.D4R7.B2 (empty) -> install TCSPM proto Slot TCSM.A5R7.B2 (empty) -> install TCPCH (crystal goniometer) Slot TCP.C6L7.B1 -> Replaced by TCPP proto A6R7.B2 -> Slot to be created for TCPCV (crystal goniometer), system from TCSM. The services are supposed to be already prepared for the new slot Inigo Lamas Garcia

Procedure: EYETS 2016-2017 New slot: 6L7 Removal: Marking beam axis and collimator origin by Survey Collimator support and plug-in installation (EN-ACE-COS) Main water connections installation (pending inspection) Cable installation Removal: Removal of the collimator from slot with Palfinger by HE Transport to RP storage in dedicated box Installation: as from 15th of February Transport to LHC location on dedicated trolley Installation of the collimator to slot with Palfinger by Transport team Collimator alignment by Survey team Collimator bake-out by Vacuum team Collimator commissioning

Preparative @ Technical Stop 2016 Check Presence of all systems: Water connections Electric cabling Collimator base/plug-in or survey mark (new slot case) Space free - Interference risks 5th axis for TCSPM At following locations: Slot TCP.C6L7.B1 Slot TCSM.D4R7.B2 Slot TCTPH.4R5.B2 Slot TCL.4L5.B2 Slot TCSM.A5R7.B2 New slot in A5R7.B2

EYETS 2016-2017 In summary: New slot creation: Marking of the floor by Survey team Collimator support and plug-in installation Main water connections installation Electric cabling Collimators Uninstallation: Removal of the collimator from slot by HE Transport on dedicated trolley to surface Transport to RP storage on dedicated box

Installation: available from 15-02-2017 EYETS 2016-2017 Installation: available from 15-02-2017 Collimator Installation: Transport to LHC location on dedicated trolley Installation of the collimator to slot with Palfinger by Transport team Collimator alignment by Survey team Collimator connection bake-out by Vacuum team Collimator commissioning

Maintenance work EYETS 2016-2017 RadMon maintenance Replacement by approx. 100 RadMon v.5 by v.6 essentially LSS3 and LSS5 Inspection of TED recommissioning of all collimators near the end of EYETS

EYETS 2016-2017 HCTDE__001 Consolidation of dumps in caverns UD62 and UD68

EYETS 2016-2017 Main dumps Venting in order to exchange the joints and gaskets on the two dumps, as foreseen.  [VSC & STI] Reduction of the nominal Nitrogen pressure to 1.1 bar in order to avoid the opening of the relief valve during high intensity dump. [VSC]

EYETS 2016-2017 Main dumps Exchange seals and gaskets on both dumps.  [VSC & STI] Modification of the flanges. [STI] Test of the spare in the UD. [STI, VSC]

EYETS 2016-2017 Main dumps Open the dump shielding in order to access the downstream TDE window for a leak detection. (UD62 and UD68)

Replacement of the first TIM series unit EYETS 2016-2017 Replacement of the first TIM series unit Installation in CMS Bypass (TIM garage) TIM 3 will run from IP2 to IP5 TIM 2 will run from IP5 to IP8 4 hours needed + test runs
