  1. Summary of WG5 activities (Engineering, Layout, Solenoid, Cost) K. Elsener, LCD meeting 21 February 2011

  2. Note: last WG5 summary was given in July 2010 However: update on activities given at the IWLC, October 2010 H. Gerwig: MDI Integration at CLIC http://ilcagenda.linearcollider.org/getFile.py/access?contribId=229&sessionId=83&resId=0&materialId=slides&confId=4507 Gaddi: Passive isolation: Pre-isolation for FF quads http://ilcagenda.linearcollider.org/getFile.py/access?contribId=232&sessionId=83&resId=1&materialId=slides&confId=4507 B. Cure: Study of a 5 Tesla large aperture coil for the CLIC detector http://ilcagenda.linearcollider.org/getFile.py/access?contribId=91&sessionId=83&resId=0&materialId=slides&confId=4507 Herve: General Detector Motion System Issues (Push-Pull @ ILC) http://ilcagenda.linearcollider.org/getFile.py/access?contribId=161&sessionId=29&resId=1&materialId=slides&confId=4507 Today: some words on “what happened” since IWLC2010

  3. WG5: one of the “CDR preparation Working Groups” Draft of chapter 9: Superconducting solenoids and magnet systems http://indico.cern.ch/getFile.py/access?subContId=0&contribId=1&resId=0&materialId=1&confId=115032 Draft of chapter 11: Very forward calorimeters http://indico.cern.ch/getFile.py/access?contribId=1&resId=0&materialId=slides&confId=118318 Draft of chapter 13: Interaction region and detector integration http://indico.cern.ch/getFile.py/access?subContId=1&contribId=1&resId=1&materialId=2&confId=115032 Draft of chapter 16 : Cost methodology for a CLIC detector http://indico.cern.ch/getFile.py/access?contribId=1&resId=1&materialId=2&confId=115041 + MDI sections of CLIC accelerator CDR (now Vol. 1) in chapter 2:http://indico.cern.ch/getFile.py/access?contribId=4&resId=2&materialId=paper&confId=113417 in chapter 5: http://indico.cern.ch/getFile.py/access?contribId=4&resId=3&materialId=paper&confId=113417 + several LCD Notes

  4. Reminder: Layout and Integration NB. will write a note on differences in geometries between GEANT4 and the Engineering Layout

  5. Update: FF quads pre-isolator support Reminder of passive support “block” in layout:

  6. Update: FF quads pre-isolator support Reminder of test set-up in point 5:

  7. Update: FF quads pre-isolator support Reminder of test set-up in point 5: 40 ton dead-load Support beams 4 tapered steel beams

  8. Update: FF quads pre-isolator support Detailed calculations and proposed improvements (F. Ramos et al.) new measurement series to start 23 February 2011 1.1Hz 57.2Hz Initial design 17.8Hz 6.7Hz 1.3Hz 31.5Hz New design 72.7Hz 8.7Hz Isolation

  9. Update: anti-solenoid CDR model is now “frozen” Ferromagnetic disc (Permenorm 5000 s4) Low current superconducting coils 12 – 0.1 – 3.5 – 15 – 28 A/mm2 Improved shape winding 80 A/mm2

  10. Update: anti-solenoid CDR model is now “frozen” Bzfield profile along beam line (CLIC_SiD)

  11. Rutherford SC cable Pure Al stabilizer Reinforced Al stabilizer AA reinforcement Update: SC conductor R&D – main detector magnet Conductor overview 5T, 5 layer 18kA, 40 strand cable Atlas CS Atlas BT CMS Atlas ECT B. Curé - A. Gaddi / CERN Physics Dept.

  12. Update: SC conductor R&D – main detector magnet Preparations under way (in collaboration with KEK) Collaboration with industry Schedule depends on “them” -> first tests foreseen second half of 2011 B. Curé - A. Gaddi / CERN Physics Dept. Co-extrusion press at Nexans

  13. Update: Detector Costing and Costing Tool • “mini-meetings” on CLIC detector costing : • list of agreed unit costs • draft chapter on detector costing • critical analysis of CLIC costing tool -> feedback • -> new version, will starting using it 22 February • Goal: internal cost estimate, not part of CDR Vol. Phys. & Det. • (but get relative contribution of costs – cost drivers, • and an analysis of sensitivity to e.g. cost for steel, etc.)

  14. Update: Detector Costing and Costing Tool agreed unit costs (CLIC and ILC detectors will use same costs)

  15. Update: Detector Costing and Costing Tool
