Description
The ATLAS experiment will upgrade its Pixel Detector with the
installation of a new pixel layer in 2014. The new sub-detector,
named Insertable B-layer (IBL), will be installed between the existing
Pixel Detector and a new smaller radius beam-pipe at a radius of 3.3 cm.
To cope with the high radiation and pixel occupancy due to the
proximity to the interaction point, a new read-out chip and two
different silicon sensor technologies (planar and 3D) have been developed.
Furthermore, the physics performance will be improved through the
reduction of pixel size while targeting for a low material budget
should be imposed, pushing for a new mechanical support using
lightweight staves and a CO2 based cooling system.
An overview of the IBL project as well as the present experience in its construction will be presented, focusing on the staves production,
qualification of the assembly procedure, integration of the staves
around the beam pipe and commissioning of the detector.
