Description
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 (HI-LHC)
project. The upgrades for the ATLAS detector will be staged in preparation
for HI-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 a 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 a 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 with particular emphasis on irradiation and beam tests will
be presented. This talk will also summarize the improvements expected to
the ATLAS detector at the HI-LHC.
