The first few months of 2006 saw the delivery to CERN of the final components of the ATLAS semi-conductor tracker (SCT), namely the completed SCT end-caps.

The SCT barrel arrived in sections in 2005 and was assembled later that year. And as reported in this issue of the eNews, the barrel SCT has recently been integrated with the barrel Transition Radiation Tracker.

The end-caps were constructed in Liverpool (side C) and NIKHEF (side A), using components manufactured at many different sites across the world.
