Note for the end of 2014 LHC will restart with beam in autumn 2014 It is not planned to have a stop of LHC beam operation at Christmas 2014 – 1 week of standby for LHC & Injectors – Consequences for maintenance activities??? – FT programs will have a normal stop from December 2014 to April LS1 Day: The Injectors8

9 What will run in 2013? EN/MEF Coordination teams

What will run in 2013? Main constraint is CV maintenance – PS Complex water off in May, June & July LINAC3 – Test with new ions for NA operation – Mid-January for 13 weeks (Argon) – Early August for 13 weeks (Xenon) CTF3 – March to November – Stop 3 months in summer ISOLDE – REX-IBIS 3MeV test stand – February to April – August to December with a new source LS1 Day: The Injectors10

Reminder: What will not be done… LS1 Day: The Injectors11

Reminder: What will not be done… SPS Cable clean up around BA5 Replacement of irradiated cables BA1 Replacement of all irradiated cables TCC2 & TDC2 – Look at replacing a limited number of cables to avoid duplication of work and reduce overall dose? All preparations for the connection of Linac4 to the PSB before LS2 PSB cable clean-up (requested but never formally agreed) – Some preparatory work to at least identify cables? EAST Area cabling NA62 ventilation in NORTH Area – Must be done in the 2014/15 NORTH Area stop LS1 Day: The Injectors12

What will be done Consolidation and maintenance work – all groups Replacement of PS Complex access system – 28 access points, 100 doors – Both systems to run in parallel during 2014… – The time critical activity New PSB Interlock system Replacement of the PS tunnel ventilation system – Requires sealing of PS tunnel & TT2 (not a trivial exercise!) New PS beam imminent warning system (BIW) Addition of shielding over the Route Goward at the PS – Major Civil engineering project which will complicated access to the PS area. Removal of 4 PS main magnets TT2 magnet renovation LS1 Day: The Injectors13

Vertical re-alignment of SPS between 5 & 6 – Needs displacement of the support jacks Full re-alignment of all machines Replacement of the SPS main power supply transformers Replacement of approximately 15 SPS main magnets Change of 12 additional SPS main magnets for e-cloud vacuum chamber coating LS1 Day: The Injectors14 What will be done

How are we organised Now we have the list of things to do – Aim to produce a first resource loaded realistic schedules for Injectors – Planning and Coordination meetings – Detailed discussions with Groups (dedicated contact people) Machine Coordinators = the Usual suspects – AD & PSB: Nicolas Gilbert – (PSB: D Hay handover date to be defined) – PS: Ray Brown – SPS: David McFarlane – Other problems concerns: Vinod Chohan or Simon Baird LS1 Day: The Injectors15

How are we organised? We will start from the information already collected and all the approved activities entered into the PLAN database Please inform us about new activities Major new activities must also be entered in PLAN – Management approval IMPACT tool will be used as part of the planning once we have the baseline schedule – Access Control – Activity completion – Documentation control ECR’s etc LS1 Day: The Injectors16

How are we organised? LS1 Day: The Injectors17 A situation to avoid….

A few outstanding questions to be addressed No cable clean-up in BA5 – Is there an issue for cabling for new installations around BA5 (SPS) – BI requests…. No cable clean-up in PSB – Again is there an issue for cabling for new installations – BI equipment – EPC new power converters – Interlock systems – New ABT equipment… Renovation of TT2 magnets – Can we really remove renovate and re-install up to 39 magnets?? – Can we do this work in situ? LS1 Day: The Injectors18

AD (on top of “standard” activities) RF and Stochastic cooling consolidation Removal of a main dipole – Preparation of a magnet consolidation program for AD Removal of unused transfer lines (7000, 8000, ATP) and general clean up to prepare for ELENA A delay of AD shutdown 2014/15 is under discussion to allow for a delay of… – Additional works for ELENA & Gbar installation – New building (kickers storage etc…) LS1 Day: The Injectors19

NORTH Area NA62 ventilation separation is delayed until 2014/15 North area shutdown – 2014 run for NA62 will need RP mitigation measures – Reduced beam intensity – Long flushing periods before access to experimental cavern GIF++ installation in H4 NORTH Area long-term consolidation – Prioritized plan starts in 2013 and continues … – In 2013 TCC2 & TDC2 works (with a limited replacement of irradiated cables t.b.c…) LS1 Day: The Injectors20

EAST Area DIRAC will be removed to make way for a new irradiation facility This is the first step in the EAST Area renovation as presented at the EAST Area Day LS1 Day: The Injectors21

Conclusions Now we can get started – Business as usual = Coordination meetings… – PS Complex access system is the time critical item – SPS: Two major activities have been removed – Please inform us of changes to your needs (MEF Coordinators and PLAN) Some questions – BA5 and PSB: Will we install equipment without new cables? – TDC2/TCC2 Can we make a limited cable replacement campaign? – TT2 magnet renovation? – Is non-stop operation from early 2014 to the end of 2015 a concern? – …..
