  1. SCT Production Status ‘Snap-shot’ of the status of the SCT production (May 2003) • Barrel Modules • Barrel Opto-harnesses • Barrel support structures & cooling • Endcap Modules • Endcap Opto-harnesses • Endcap support structures & cooling • Power & Cables • Off-detector readout • Assembly & Integration

  2. Barrel Modules • Modules • Barrel module PRR May 01 • Detector production May 03 ( I.e. complete) • Hybrids target end date Aug 03 1214/2500 (49%) • Baseboards target end date Oct 03 1481/2530 (59%) • Modules-Japan 356/ 786 (45%) • Modules-UK 79/ 549 (14%) • Modules-US 48/ 483 (10%) • Modules-Scand (qualification soon) 16/ 404 ( • Total (2112+5%) 499/ 2218 (22%) • Modules target end date Apr 04

  3. Barrel Optoharnesses • Opto-harnesses • Production now underway after slow start-up • Main problem was ESD damage to DORIC ASIC • First 2 harnesses fully evaluated • Schedule can be recovered • B3 Jun 03 • B6 Jul 03 • B5 Sep 03 • B4 Oct 03

  4. Barrel Structure & Cooling Support structures • All 4 CF cylinders delivered • …but there are ~40000 small parts! Cooling • Design is finalised • Production of cooling circuits underway • On critical path

  5. Endcap Modules • Modules • Endcap module PRR Aug 02 & Nov 02 • Hybrid design was validated as suitable for production • Hybrid production & assembly transferred to industry • Thermal performance validated • Production • Hybrids • Pre-series of 200 in production – some delivered • Full order for 2500 placed • Spines • 200 in production by Protvino/MPI • Contract in place for 2500 • Module assembly • All 3 clusters have started ‘qualification’ process • 1rst modules within specification • Aim is to have all sites qualified in 2 months • Goal is to complete module production in Sep 04 • Very ambitious – will require extra resources

  6. Endcap Optoharnesses, Structure & Cooling • Opto-harnesses • Simpler as the electronics is incorporated in the hybrid • Production can start as soon as fibre lengths finalised • Cooling • Design is finalised & prototyped • Production of cooling circuits ready to start • Support structures • CF disks & support cylinders ordered • First 4 delivered; complete by Dec 03 • Again many small parts • 4 first disks & Stub cylinder delivered • Expect delivery of cylinders by Aug 03 • Disk PAR MAY 19 • Critical issue is to complete disc machining by July

  7. SCT Power, Cables, Readout, Assembly & Integration • Power & Cables • System designed & all elements prototyped • FDR/PRR scheduled for May 28 • Early production necessary for macro-assembly • Cable tender in June • Readout • System designed & all elements prototyped • FDR/PRR May 13 • Early production necessary for macro-assembly • Assembly & Integration • B3 is at RAL to be equipped with services • B3 will go to Oxford to have modules added Jul 03 – Nov 03 • SR building at CERN now available • Program of work underway to commission cooling, power & readout
