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

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

ATLAS ATLAS SCTSCT

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

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
