ATLAS ATLAS SCTSCT
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
M. TYNDEL 4 LHCC Interactions May 2003
ATLAS ATLAS SCTSCT
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
M. TYNDEL 5 LHCC Interactions May 2003
ATLAS ATLAS SCTSCT
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
M. TYNDEL 6 LHCC Interactions May 2003
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
