  With the LHC collecting data at 7 TeV, plans are already advancing for a
series of upgrades leading eventually to about five times the LHC design
luminosity some 10 years from now in the High Luminosity LHC (HL-LHC) project.
The upgrades for ATLAS detector will be staged in preparation for HL-LHC. The
first upgrade for the Pixel Detector will be the construction of a new pixel
layer, which will be installed during the first shutdown of the LHC machine
foreseen in 2013-14. The new detector, called the Insertable B-Layer (IBL) will
be installed between the existing Pixel Detector and a new, smaller radius
beam-pipe at the radius of 3.2 cm. The IBL will require the development of
several new technologies to cope with increased radiation and pixel occupancy
and also to improve the physics performance through reduction of the pixel size
and more stringent material budget. Two different and promising Silicon sensor
technologies (planar n-in-n and 3D) are currently under investigation for the
IBL. An overview of the IBL module design and the qualification for these
sensor technologies are presented in this proceeding. This proceeding also
summarizes the improvements expected to the ATLAS detector at the HL-LHC.
