  1. SCE EC Design & Manufacture Jason Tarrant (RAL) • Progress of SCT EC • Support Structure (Required for Disc Assembly 2004) • Services (Required for Disc Assembly 2004 / Integration 2005) • Thermal Enclosure (Required for Integration 2005) • PPF1 (Required for Integration 2005 / Some parts for Disc Assembly 2004) CCLRC

  2. SCE EC Design & Manufacture • SCT EC Discs CCLRC

  3. SCE EC Design & Manufacture • SCT EC Support Structure - Complete CCLRC

  4. SCE EC Design & Manufacture • Support Structure Fit Check CCLRC

  5. SCE EC Design & Manufacture • Support Structure Fit Check CCLRC

  6. SCE EC Design & Manufacture • Support Structure Fit Check CCLRC

  7. SCE EC Design & Manufacture Load 250kg -Predicted Deflections 223um-508um -Actual Deflections ~40% higher on average but within 2x safety factor = good correlation • Load Test CCLRC

  8. SCE EC Design & Manufacture • Metrology, Disc Fixing Inserts & Assembly prep. ^125 – 150um from end to end (500um max. tol.) CCLRC

  9. SCE EC Design & Manufacture • SCT EC Services – Being delivered / In manufacture CCLRC

  10. SCE EC Design & Manufacture • Services • Flexible (LMT, Optical fibre, DCS) • Lengths determined using spreadsheets, computer simulation & physical Mock-up + independent review • Rigid (Disc Cooling, LMT Cooling, N2 Purge) • Lengths determined in CAD, prototypes in process of manufacture (RAL / QMUoL) CCLRC

  11. SCE EC Design & Manufacture • SCT EC Thermal Enclosure – Final Design CCLRC

  12. SCE EC Design & Manufacture • Thermal Enclosure Parts • Inner Thermal Enclosure (ITE) • Same Design but no heaters • Outer Thermal Enclosure (OTE) • Single piece, different mounting (no mechanical force) & no cooling circuit • Rear Thermal Pad • Same design but no cooling circuit • Services Thermal Feed Through (STFT) • Same Design • ITE – Rear Support Cover • Same Design • N2 Purge • Same design • Heaters • Final designs being tested then ready for manufacture • LMT Cooling • New, using spare ways from disc cooling CCLRC

  13. SCE EC Design & Manufacture • Thermal Enclosure • Analysis / Audit • Peter Ford ATL-IS-EA-0006 • Manufacturing issues • Detail design after FDR (29/09/04) CCLRC

  14. SCE EC Design & Manufacture • PPF1 – Manufactured / Final design CCLRC

  15. SCE EC Design & Manufacture • LMT / Optical Fibre / LMT cooling Type 2 Cable clamp LMT cooling connectors Optical fibre compartments Back-plate for connection to Raphael’s Curved plate Rigid back-plate Sides to be covered with aluminised Kapton sheet Space for Type II wires Housing for PCB trays LMTs Connection to Cryostat cable tray CCLRC
