  2. Technical Coordination 3-fold mandate • - assure the provision of host lab technical support to the experiment • (≥ provisions guaranteed under “General Conditions for Experiments”) • surface assembly buildings and underground caverns • primary infrastructure and services (eg power, water, parking) • core expertise (eg safety advice and oversight) • -manage the provision and operation of common elements of the technical project and • identify and coordinate additional common programmes. • eg solenoid, shielding, cooling system, detector power, BRM, common cabling teams..... • assure safe design, fitness for purpose, timely and cost-effective delivery and coherent, • safe, installation + operation of detector systems • including compatibility with: • existing detectors and detector infrastructure • CERN host infrastructure, • accelerator complex • CERN rules & host state regulations.

  3. TC and upgrade Boundaries are blurry: “technical operation Technical Coordination “maintenancc” “construction” “upgrade” “consolidation” Common TC structure and reporting lines cover all types of activity TC defined “consolidation & upgrade” as: ALL changes of configuration after Sept 2008 (ES, UPS, farm cooling, Gazprom, mag shields, BRM, ZDC, etc etc)

  4. TC essentials for upgrade (from May 08 upgrade workshop) • -Consolidation & Upgrade common fund (additional to M & O A and CERN as host funding). • -Safety team (+ subsystem links) • -Engineering + technical teams for infra & common systems, plus general elec & mech support • -Mechanical, Electrical and Electronic Integration Team (homogeneous) • -Planning and logistics teams (includes full ALARA dose planning) • -Recognised review process, including external referees, as applied to CMS so far. • (TP-TDR) -PRR-EDR/ESR(several)-MPR(several)-ECR-POR-TIP etc • - As-built engineering model and the Equipment Management Database, • (the essential starting points of any intervention on the detector). • Subsystem “field coordinators” • -Collaboration teams with detector expertise as common resource for subsystems

  6. Technical Reviews Principle defined in Constitution of the CMS experiment, Section 6.7: "Before launching the construction (or modification) of major parts of any CMS sub-detector or sub-system, or engaging in major related expenditures, the Technical Coordinator, with the agreement of the relevant sub-project manager, organizes reviews to confirm the soundness and completeness of the chosen design including the coherence of all interfaces with respect to neighbouring sub-detectors or other parts of CMS; the aim being to minimize risks in cost and schedule". review types: PRR, ECR, ESR, EDR : (follow-ups usually needed) In addition: “Each subdetector will undergo one or more MPRs (Manufacturing Progress Reviews) at strategic moment(s) of the production process. The Technical Coordinator will decide which production processes merit MPR's. The MPR committee will ascertain whether the manufacture is going as planned, whether the quality requirements and milestones are likely to be met and whether the resources (financial and human) required to complete the production are available.” And in practice we also introduced “installation EDR’s”, prior to installation of items in CMS. The same review process is being applied to consolidation and upgrade

  7. Consolidation & Upgrade Reviews and workshops 2011 Done and reports complete or in final editing: PLT MPR 17 Jun 2011 CASTOR ECR 30 Jun 2011 ME1/1 ECR/ESR 08 Jul 2011 BSC upgrade workshop 22 Jul 2011 YE4 assembly & installation 15 Sept 2011 ZDC crane 28 Sept 2011 (Inst rev still reqd) Imminent: PLT MPR follow-up 17 Nov 2011 RPC4 EDR 24 Nov 2011 CASTOR “ show & tell EDR” 14 Dec 2012 Shielding Dec 2012 ??

  8. Host lab & Common Project progress Brief update on some selected projects: Common facilities (Surface buildings 678,904,892,SX5) Common systems (Magnet, RP shielding) Endcap Muon (YE4) Tracking (45mm o/d beampipe)

  9. Surface facilities: 678 : 500m2 storage “tent” Critical to the logistics sequence of liberating ISR and re-equipping SX5 Nov 2011: another tent will be needed to clear tooling in ISR

  10. Surface Facilities: 904 zone A.Sharma, D. Hay

  11. Surface Facilities: 892 Duplicate workshop & ECAL labs displaced from 867 by LHC machine Cryo equipment removed. Floor pits filled. Platform refurbished. 867 released for LHC radiation w/shops Outer shell/door still requires work. ECAL test stations + ETHZ workshop available again. 867 released for LHC radiation w/shops Party imminent!

  12. Surface Facilities, Pt 5: SHL 1’st floor nearing completion Delivery of pixel cold/clean(ish) lab not possible in time for YETS 2011-12. Contingency plan in case of BCM/pix removal was to transport to TIF. Blockages due to RP shielding & quake tolerance issues Will be ready for LS1 for 18 deg operation. 16/03/2011 Martin.Gastal@cern.ch David.Hay@cern.ch 13

  13. Common Systems, Infra & Facilities: Magnet Benoit Cure Magnetic field off: ~ no useful physics Magnet on-off-on: limited number of such cycles in lifetime (200-300?) Highest priority: Redundant Helium compressor pair - critical single point failure : 7 mo recovery! - replacements now only built to order, but provision for redundant pair foreseen - identified pre-purchases (effectively compressor spares: rotors, bearings etc) to reduce downtime to 1 mo. - Order placed (CERN funds: contribution or loan) 14

  14. Common Systems, Infra & Facilities: RP shields A.Surkov, Wolfram Zeuner Finalising design of RP shielding from Tracker Bulkhead to 11m . Single set of tooling, supporting shield from below, compatible with all activities. -Aim to complete design by early autumn. -EDR this year if possible. -Start manufacture 2011. -Full test in LS1 (before needed for ALARA)

  15. New CMS central beampipe Ball, Bacchetta, Schaefer, Zeuner, EIC, TE-VSC 3120 support Issues: Impedance, HOM etc: shape OK Vacuum impedance: OK . Support collar on cone at 1630 mm: OK Aperture OK : approved by LEB, LMC Materials and Construction: Cones 1450 -->1948 machined from AlBe Considering replacing SS conical section (up to bellows junction with Endcap pipe at 3.12m) with AlBe. AlBe to Be braise to be studied Lighter pipe, as strong, reduces sag, activation and backgrounds, eliminates transition piece. CMS E & I, for C. Schaefer

  16. Beampipe upgrade: simulation Moritz Guthoff – Staus: CMS BRM • New geometry implemented in FLUKA • Changes: • Radius of cylindrical part smaller • Conical part changed from stainless steel to AlBeMet. • Pixel layer 1 at smaller radius • Simulations use beam background simulated by N.Mokhov PIXEL OLD Conical BP & flange St.steel->AlBeMet Cylindical BP (Smaller) Moritz Guthoff - Staus CMS BRM

  17. Moritz Guthoff - Staus CMS BRM PIXEL OLD NEW Charged hadrons BEAM Preliminary neutral hadrons electrons 18 Moritz Guthoff - Staus CMS BRM 6.10.2011

  18. Endcap Muon Upgrade YE4 shielding disk: material qualified, first steel sector cases being assembled Complex assembly tooling designed and in purchase procedure. “push-back” system nearing completion. Assembly EDR held in Sept CSC4, RPC4, ME1/1 front end: Review process ongoing .

  19. YE4 shielding disk: milestones NB Date format !!!!!

  20. Tracking (Pixel/beampipe) upgrade timing Milestones for new beampipe • Mechanical params for aperture calc Jun 2011 Complete • Material (!) and integration studies July 2011 Complete • LEB approval Aug 2011 Complete • LMC approval Aug 2011 Complete • Call for tender Sept-Nov 2011 Complete • FC approval Dec 2011 • Finalise design Jan 2012 • EDR Jan 2012 • Place order: Feb 2012 • Delivery at CERN: mid 2013 • Testing complete Nov 2013 leaves time for 1 weld re-work. • Ready for installation Dec 2013 milestone in common with LHC

  21. LHCC Milestone Level definitions from LHCC meeting, 15 June 2004, updating 15 Mar 1999 Level 1 milestones: are derived from the overall planning for CMS assembly & usually represent changes of dominant activity on the critical path towards readiness for beam operation. Level 2 milestones: are defined by sub-system managers and represent key benchmarks in sub-detector progress towards the relevant level 1 milestones. Level 3 milestones: are defined by sub-system managers to complement the level 1 and 2 milestones by providing a more detailed breakdown of objectives and a mechanism for intermediate monitoring of major tasks in progress. L2 “ready for installation” milestones and “schedule float” - L2 “ready for installation” milestones mark the date from which a major section of the detector is intended to be ready be used in the master assembly sequence. - They allow flexibility in tuning the master assembly sequence without impacting subdetector planning. - The target float from the critical path is 3 months (usable as contingency during last year of construction, by agreement with Technical Coordination).

  22. Example: v34.2 UX schedule overview Level 1 milestones mark major activity changes on CP Level 2 RFI milestones show the latest date where an item is "on the shelf " ready to use on CP.

  23. YETS 2011-12: Focus now P-spikes 18.3m R5 • Suspects: physical aperture problem • desorption instability due to adsorbed gas • TC CONSIDERS THIS THE DOMINANT KNOWN RISK TO 2012 OPERATION • YETS 2011-12 planning is therefore being re-designed to give priority to: • Radiography of both ends around this region and survey check from 13m to 50m. • Bakeout –z end beampipe for 18  3 m ( same for +z end if radiography reveals no fault) • Activate a so far unused NEG cartridge to double the pumping speed • (increased threshold for desorption instability) • Install additional instrumentation in the 18  3 m region. • THIS ACTIVITY IS INCOMPATIBLE WITH OPENING THE YOKE • but the planned programme with yoke closed can still be done – with added difficulty

  24. YETS 2011-12 main activities Survey, radiography and bakeout of 18  3 m region Installation of the much-delayed ZDC crane (last chance - activation) Validate CASTOR calorimeter insertion with beampipe at vacuum. Install PLT demonstrator on CASTOR table at +z end (subject to MPR 17 Nov) Remove BSC to preserve for heavy ion programme provide for tests of BSC 2 technology (focussed on beam-halo) Replace components in one HF RBX’s Install CSC4/RPC4 posts and RE4 demonstrators Re-work Muon Barrel DT system LV connectors New crane in CV room Obligatory & advisory annual maintenance of services Tests of AUG, Diesel backup, Evacuation etc Re-verification of alarm action matrix (minimising collateral damage risks) Input from Divonne TC workshop: 17 weeks needed to justify opening detector. Including vac work, 20 weeks would now be needed. --> Little prospect of getting a head start on LS1 work (such as Tracker humidity seal)

  25. Draft LHC baseline planning LS1 24 months physics to physics, 20 months beam to beam Input from CMS: need 20 months, starting no earlier than Dec 2012 • Sequencing & • Co-activity being • understood. • Timeframes • less convincing • LHC preferred start • date 17 Nov. • Many resources • from Institutes • Interference with • expt resources?

  26. CMS draft planning LS1 Martin Gastal: for detail see his talk Nominal BP RFI Await tender discussions to see if it could work Beampipe installed Tracker --> cold operation is given priority : leads to complex logistics CMS need 24 months beam to beam to be comfortable: working on alternative sequences

  27. LHC plan post-LS1 & phase 1 pixel insertion Case made to LMC for beampipe approval Aug 2011: Unless we think there is a possibility of phase1 pixel being ready in late 2014, we should stick with this message: synergy with LINAC4 connection is likely.

  28. Concerns: there are many! -Cash needed in 2011- 2014 -Likelihood of a chaotic year for finances in 2012 -Maintaining the base of technically competent personnel eg common systems experts field coordinators -Draft LS1 plan: beampipe rfi is late HO HPD —> SiPM on YB0 is high risk and lengthy contingency for re-opening after CRAFT has started insufficient --> 24 months beam-to-beam needed to be comfortable -YE4 delivery: assembly pushes RP area completion in SX5 into LS1 -SX5 (OSC+ SL53) facility progress slow/blocked -Completing retreat from ISR

  29. Host Lab & Common Project 2012-14 As in other projects, will need to decide what’s essential? • Facilities: • 904, SX5 (OSC) completion, additional buildings to house remaining ISR equipment. • Magnet & Common Systems • RP shielding, Opening system consolidation. • Cryo compressor redundancy. • UPS system extension in USC. • Endcap Muon • YE4, YE4 pushback • YE3 manifold mods for RE4, • (YE1 cooling manifold accessibility?) • Tracker • Beampipe, • Humidity Control (seal), N2 high capacity, CO2 cooling integration. • h>3 • CASTOR insertion with bp at vacuum, beampipe support consolidation
