The ATLAS SCT (semiconductor tracker) is a major component of the inner detector being built for the ATLAS experiment at LHC. It comprises 2112 barrel modules mounted on four concentric barrels of length 1.6m and up to 1m diameter, and 1976 endcap modules supported by a series of 9 wheels at each end of the barrel region, giving a total silicon area of 60m2. At The University of Oxford, a pair of custom robots has been used to mount modules onto each of the barrel structures. After a few rows have been completed, the modules are electrically tested using a subset of the data acquisition and power supply hardware that will be used in the final experiment. The evaporative cooling and detector control systems used throughout are also similar to those that will be used in ATLAS. This presentation highlights the electrical performance of the SCT barrels, the largest of which has an instrumented silicon area of approximately 10m2.
