Joint Meeting ATLAS-CERN Detector Group / PH-Detector Technology Group Overview of the PH-DT group: Group Structure Current Projects Services White Paper R&Ds Future Projects Christian Joram 21 April TA1 TA2 TA3 DT1 DT2 DT

2 Mandate of DT group The mandate of the PH/DT group comprises development, construction, operation and maintenance of particle detectors for the experiments at CERN. The group clusters common services and infrastructure which are at the benefice of all experiments at CERN, i.e. gas system support, thin film lab, silicon facility with bond lab, irradiation facilities, magnet support, B-field mapping, instrumentation and controls. 1 meeting/year a meeting / every 3 weeks

Campbell) A. Honma White Paper R&D project

Engineering R&D (discussion forum in 2008, 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 CMX/DT/TE-CRG team has started to study suitability of CO 2 cooling for larges scale detectors. Pilot case: CMS pixel det. upgrade; (≠ CO2 cooling plant development). Timescale 18 months. o is now part of WP11 / DCP.  Reverse engineering = 3D models for high accuracy reconstruction of built structures. DT/BE- ABP. 1 shared fellow. Has started. Applied to ATLAS Inner Tracker services.  Material for future detectors (structural, thermal, radiation hard, pipework and joining techniques). Not yet really started. Overlaps a bit with WP7.

9 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 Current involvement + vague options in LHC upgrade projects … (<2 FTE) ATLAS upgrade: participation to PO / engineering + … CMS upgrade: engineering, cooling study for upgraded pixel, pixel luminosity telescope, humidity measurement LHCb upgrade: VELO upgrade (40 MHz), RICH ALICE upgrade: VHMPID, pixel (cooling) TOTEM upgrade: Large GEM (T1), part of WP5 … we would like to start soon! … has already started

10 Detector cooling Autumn 08, DT proposal: Launch a common detector cooling activity in PH-DT (in analogy to our gas systems activity), preferably merged with EN/CV-DC section. Many discussions took place, on various levels. In the end, the merger was refused by EN management. A CERN wide Detector Cooling Project (~Working Group) was recently created, chaired by M. Battistin. DT is represented by P. Petagna. Current DT situation – not 100% clear -We contribute (modestly) to consolidation of CMS C 6 F 14 system (leak testing, rack assembly) -We are involved in a CO 2 cooling feasibility study for a future CMS pixel det. How to continue ? -We still think that detector cooling is of highest importance for upgrade -We still want to contribute to detector cooling: on-detector thermal aspects, piping, joining techniques; to a lesser extent but not excluded: cooling plant design/construction -We still see synergies with our gas systems and magnet controls activities

11 Detector cooling Near future plans -PhD project: Dynamic performance and process modeling for the future cooling systems (A. Moraux) -Recruitment of 2 engineers, directly related to detector cooling (incl. consolidation, operation of existing systems). -Look for projects and opportunities to gain expertise and apply our resources
