The University of Geneva was responsible for the barrels structures and integration with all the corresponding tooling. All the barrel design and associated parts as well as the integration stands were made at the University.

The University of Geneva was responsible for the production of a large part of the outer forward SCT modules now mounted on the two endcaps A and C that are now installed in the Inner Detector of ATLAS. In total 655 modules were produced with a yield of 97.7%.

This production which started in 2003 was preceded by several years of development phase mainly for the assembly tooling, the testing, the debugs and the QA tuning.

The University of Geneva was largely

involved in the commissioning of the

endcap and the barrel in the surface building at CERN which was followed in 2007 by the installation in the cavern.

The University of Geneva was responsible for the implementation and the on-site maintenance of the environmental Detector Control System (DCS) which monitors the temperature and the relative humidity of the SCT together with the interlock.

The University of Geneva led the barrel sector reconstruction at CERN SR1 in 2008. This sector is permanently used at CERN for the SCT shift training and for the DAQ development.
