New organization CERN – Detector cooling. Transfer of activity to PH (i.e. most likely DT) under discussion – TS/LEA gas supply: Transfer of activity to PH/DT (will possibly happen). – TS/LEA EAM. Will merge with some people from AB/ATB (Gatignon, EFTHYMIOPOULOS, etc.) + a LHC planning group (?) to engineering dept (EN). – TS/SU: will become a section in AB/ABP – IT/CO: will be merged with some people from AB/CO and then form a group in engineering department, GL Roberto Saban. PH would like to preserve JCOP, and also Wayne as coordinator. DT structure – Allain Gonidec stays Dep. Dep. Leader (DDL) throughout 2009 – 2nd DDL position (currently M. Doser) will be suppressed – Linear Collider / CLIC detector study L. Linssen in charge, together with W.D. Schlatter + some fellows/students – A. Gonidec will from 2009 on be in charge of White Paper R&D WPs. There will be a review committee set up to assess progress and objectives. Yearly reviews. – Detector Cooling  See slides. White Paper R&D WP being created. A technical student, Joao Noite (PT), selected (supervision by Antti, prel.). Starts 1 of Jan – Discussion with A. Ceccucci on NA62 (Ferdi present). Several possible involvements of DT: e.g. straw tracker, gas systems (straws, RICH), RICH vessel, controls, Gigatracker mechanics. Approval by RB expected. Then search for funding. Draft MOU exists.

Safety matters In the new CERN organigram Safety commission seems to be located similarly as today… 4 December 20086DT coordination meeting, A. Onnela Here !

Safety matters Building repair status: – Building 25 roof being re-worked right now with heavy equipment Removal of an old concrete layer. Is the building safe during the operation? We, e.g. TSO, not too much informed … 7DT coordination meeting, A. Onnela

Workshop matters DT gluing service / succession plan for D. Fraissard: – 13 Nov: Visits to TS/MME Polymers & Resins workshop (Paolo Chiggiato) and to DT gluing lab (Daniel Fraissard) TS Polymer lab: ”Material science oriented”, electrical insulations, feed- throughs, several ovens and vacuum chambers for resin preparation and curing. ~2 technicians quasi- permanently. DT gluing lab: ”Assembly gluing oriented”, one big oven, space for lamination work and large assemblies. <1 person part-time. – Preserving and promoting the DT gluing lab seems justified, needed in our projects and complementary to what TS/MME has. – Next step: Choosing of successor(s) for Daniel Fraissard Diego Perini, Hans Danielsson, Andrea Catinaccio, Antti Onnela to meet and select candidate(s) Check with Daniel Fraissard + Christian + Ferdi + possible project leader before asking the candidate(s) 4 December 20088

PH Department / Detector Technology Group PH/DT 10 Future of Detector Cooling 1. The new detector cooling project in PH-DT Initial Mandate (preliminary) Build up theoretical and practical expertise for future ‘advanced’ detector cooling systems (PFC, CO 2, not H 2 O) Supports consolidation efforts for existing detector cooling systems Develop thermal management solutions for detector upgrades Contribute to standardization (equipment, controls) If this approach is successful it is expected that CERN can reinforce this team to a central unit, which can undertake the construction and maintenance of the future detector cooling systems. Foreseen resources 1 engineer a 2 nd cooling expert should be hired during FTE of technicians, one PJAS working on controls (already working with MB) 1 tech. Student, 1 Fellow Lab space and Mechanical support Synergies with DT gas systems and magnet controls PH will create a R&D WP (White paper funds, theme 3) for cooling.

PH Department / Detector Technology Group PH/DT Set up a Cooling Working Group (CWG) Initial Mandate (preliminary) Consolidation: ( ) -Understand shortcomings of present systems -Examine present running experience and future operation requirements (e.g. radiation aspects) -Support technical groups and experiments in improving the present systems -Define activities of common interest for the DT Cooling team LHC upgrade phase 1:Pixel Detector Exchange (B-layer in ATLAS, Pixel replacement in CMS) (2009 – 2011) -Define and examine the present requirements of the cooling systems for the new Pixel Detectors in ATLAS and CMS -Work out cooling system proposals for the pixel detectors (where possible these systems should be prototype cases for the upgrade detectors). LHC upgrade phase 2: ( ) -Define and examine the present requirements of the cooling systems for the upgrade Trackers of ATLAS and CMS. Follow up changes in the requirements (and their consequences) in a transparent and traceable way. -Work on a consensus for a common cooling technology for these systems and propose coherent and costed design layouts. The design proposals should include the control system and exploit at best standardizations between ATLAS and CMS. -Steer and rationalize the R&D projects and the construction of selected prototype systems -Work out a QA plan for the construction, installation and commissioning of the future systems.

PH Department / Detector Technology Group PH/DT 12 Experiments 3. Configuration A EN/CV DT Cooling Project TE/CRG Experiments Experiments define clear interfaces and internal structure for all cooling related issues. EN/ICE Cooling Working Group EN/CV-DC  Scope of Detector Cooling WG  The CWG mandate should extend over all parts of the detector cooling systems (including heaters or heat exchangers inside the experiments). The CWG has no executive power. The final technical choices remain the responsibility of the experiments. Foreseen composition Experiments (consolidation + future) DT Cooling Project EN/CV-DC EN/CV EN/ICE Chair  ~ 12 external groups

PH Department / Detector Technology Group PH/DT 13 Experiments 4. Configuration B EN/CV DT Cooling Project (incl. ex- TS/CV-DC section) TE/CRG Experiments EN/ICE Cooling Working Group DT manpower and TS/CV-DC merge to a DT Cooling project avoids doubling of infrastructure and resources avoids artificial split between M&O (CV-DC) and future systems (DT) efficient training of new DT personnel efficient integration of new DT personnel in consolidation efforts simplification for CWG (deals with a single cooling team) external groups

PH Department / Detector Technology Group PH/DT Organisational aspects for configuration B 5.1 Integration in DT group DT intends to split its DI (Detector Infrastructure) section into two sections Detector Cooling Gas systems Magnet controls Irradiation facilities Silicon facility / bond lab Thin Film lab SL: F. HahnSL: NN ~ 25 staff + 2 FSU B-field measurements ~ 12 staff 7 projects with project leaders.

PH Department / Detector Technology Group PH/DT Lab and office space, access to workshops B187 PH/DT Cooling B155 PH/DT Gas B166 PH/DT Mech. workshop B187 is a high quality work area (air conditioned) of about 300 m 2. It is in direct proximity to the gas systems team (welding, electrical and small mech. workshop) and to the DT main mech. workshop B166. Office space is available in B20/21.

PH Department / Detector Technology Group PH/DT Transition During the LHC shutdown period 08/09, consolidation work on the cooling systems of ATLAS and CMS is of highest importance. It should not be compromised by removols of offices and labs. Proposal: CV-DC personnel remain in their offices and labs In parallel, office space and lab space in 187 is prepared Removal around mid 2009 The formal transfer of CV-DC to PH could take place as soon as formal aspects (budgets, maintenance contract, quota for fellow and students) are clarified, ideally on 1 Jan Computational Fluid Dynamics The CFD activities, which rely currently on student and fellow manpower, supervised by M. Battistin, should be continued as a service for the whole of CERN. The service could be part of the PH cooling team or remain in EN/CV.

General approach for new projects Avoid fragmentation into too many mini projects (~1-2 FTE) Collaborate with experiment’s CERN group Try to apply available expertise and infrastructure (DSF, bond lab, thin film lab, irradiation facilities, mechanical workshops, gluing lab...) Find interesting projects to keep phys/eng/tech up to date in new technologies  Aim for ~2-3 main projects with major hardware deliverable + a couple of smaller projects. + engineering/integration/installation support First discussions took place… ATLAS upgrade: pixel endcap,  -strip tracker endcap CMS upgrade: cooling (see next slide), muon RPCs, beam monitoring, humidity measurement ALICE upgrade: HMPID LHCb upgrade: VELO upgrade (40 MHz) TOTEM upgrade: Large GEM (T1), part of WP5 NA62: Giga tracker, Straw tracker, gas systems, controls, (RICH ?) 19

13 Nov Engineering R&D (discussion forum, all LHC experiments + DT participating, moderated by L.Linssen) We expressed interest to participate in a couple of common engineering R&D activities, e.g.  Detector cooling o DT/CMX/AT-CRG intend to study suitability of CO2 cooling for large scale detectors. Pilot case: New CMS pixel det.; Timescale 18 months. o Could be extended...  Reverse engineering = 3D models for high accuracy reconstruction of built structures. DT/TS-SU. 1 shared fellow requested. Time scale 2 years.  Material for future detectors (structural, thermal, radiation hard, pipework and joining techniques).
