IBL Module Loading onto Stave and Quality Check

During the long shutdown between Run 1 and Run 2 of the LHC, a fourth, innermost, Pixel Detector layer has been installed in the ATLAS experiment: the Insertable B-Layer, IBL. The purpose of the new layer is to add redundancy against radiation damage of the B-layer, to ensure high quality tracking and improve the flavor tagging performance. New pixel silicon detector modules have been produced and loaded onto support structures known as staves, the building blocks of IBL. A total of 20 staves have been assembled. Procedures and results of the stave loading process are presented in this note.
